- PostA Feasibility Study on LPG as Marine Fuel(2012) Kjartansson, Sveinbjörn; Chalmers tekniska högskola / Institutionen för sjöfart och marin teknik; Chalmers University of Technology / Department of Shipping and Marine TechnologyWith the upcoming stricter emission rules fast approaching and the requirements for higher quality fuel, it is inevitable that there will be a change of fuel from HFO to cleaner options. These changes are driven by the knowledge of the health problems associated with emissions from ships in coastal areas. One viable option for meeting these demands for reduced emission is to utilize LPG as a marine fuel. This thesis investigates the harmful chemicals that are present in the exhaust gases, followed by introduction of LPG. Transport options for LPG and existing motor technology is presented and the feasibility of LPG as a fuel option on the European / Swedish market is studied. The conclusion from this study is that sufficient infrastructure for distribution of LPG is in place to serve potential marine market demand. Motor technology for using LPG as fuel has been developed for a wide range of power output. The economic incentive in the fuel price difference alone is likely to attract ship owners to invest in LPG fueled fleet.
- PostA study of strategy within the shipping business(2015) Lutteman, Anders; Eriksson, Victor; Chalmers tekniska högskola / Institutionen för sjöfart och marin teknik; Chalmers University of Technology / Department of Shipping and Marine TechnologyThe offshore industry is a volatile and financially demanding industry. The Black Gold is the single most important factor for the offshore industry. Having a strategy on paper and deliver it in reality are two different things. This thesis tries to link strategy from an academic perspective with how an expanding shipping company in the offshore segment delivers upon their strategy. The purpose is not to try and fill a gap between the worlds of academia and business. The aim is instead to describe the strategic difficulties connected with running a business in a volatile shipping industry. The method used is a Single Case Study of the company Offshore AS, backed up by four in depth interviews with relevant people in the organization management. The concept of going back and forth between the empirical and theoretical results gives content to the discussion and analysis which has been created in a simultaneous process defined by the methodological concepts called Systematic Combing and Generation of a Research Question Through Problematization. From a theoretical perspective, not only literature from the field of strategy and shipping has been used but also from the organizational, as well as psychological field. The choice of literature has been governed by what interviewees chose to put weight on during the interview process. Findings show that Offshore AS has a desire to pursue strategic work and develop its business further as it grows. The company is constantly facing change and new arising tasks means that they constantly find themselves putting out fires. The strategy of Offshore AS does not follow a clear path from A to Z. Instead it emerges over time. This could be described metaphorically- they have a short period when they are in a still, wide part of the river where they can think and reflect upon their strategy and be proactive. Occasionally they find themselves in a narrow, much stirred part of the river where the strategic work is set aside and changed into putting out fires. Within the organisation views of strategy and its implementation are not aligned nor shared across the organisation and the more they expand the more complex the situation becomes. This reality is being described in a model where Porters and Mintzberg different takes on strategy have been used to both support and challenge the normal view of what strategy is in reality as well as within academia. To conclude, Offshore AS evidently has two different views on the best strategy to reach these goals. There is no congruence between middle and top management's view of strategy and how important it is. These paradoxes are presented through the model and the authors conclude that the assumed room to maneuver based on the concept of “time” is dependent on what angle or perspective the viewer, researcher, or executor of strategy is choosing as their point of reference. Nevertheless, Offshore AS has an interesting period ahead and its major challenge is to better formulate and share its strategy throughout the whole organization.
- PostA teaching incentive(2012) Lindmark, Olle; Chalmers tekniska högskola / Institutionen för sjöfart och marin teknik; Chalmers University of Technology / Department of Shipping and Marine TechnologyThe change in maritime legislative demands, both national and international, has had a significant impact on the training and education within the maritime domain. The STCW Convention is the statutory text that regulates the training, certification and watchkeeping for seafarers. During the last few years, the STCW Convention has been revised to include updated group of tasks, duties and responsibilities as well as specification on the type and extent of training and education and subsequently on the training equipment used. This update is called the Manila amendment and has entered into force as of January 2012. Some parts of the maritime sector can be considered as high-risk areas and the transportation of petroleum and chemicals in bulk can be one of them due to the impact on health and environment those substances have unless handled properly. Specific demands on personnel competencies will call for a need for specific training and education as well as specific types of training equipment. Quality efforts in education and training should include parts of assessment and evaluation to monitor how well the training objectives have been met. The Manila amendment opens up for an extended use of simulators for the assessment of competency. A simulator can be a powerful tool in the learning process, but it is still very important to measure the effect that the tool has in reaching the goals outlined in the curriculum. This Master’s Thesis will show the impact of changed legislative demands in tanker education and how a cargo-handling simulator can be used to enhance student learning. It will also look into how a cargo simulator will perform in the ability to measure students’ competence in tanker handling in the light of the goals stipulated in the STCW Code.
- PostAnalysis of implementing information sharing based on maritime-related innovation platforms: a multi-stakeholder perspective(2022) Gu, Xiaohan; Chalmers tekniska högskola / Institutionen för mekanik och maritima vetenskaper; Lundh, Monica; Lundh, MonicaThe maritime industry has been influenced by rapid technological developments for decades which are also increasing the requirements of the industry and the maritime industry needs to rely on technological development and innovation as well. Information communication and te chnologies (ICT) provide various benefits to maritime management, open innovation platform as an effective form of ICT originates from innovation intermediary, playing an increasingly important role in connecting the supply and demand, promoting innovation cooperation and facilitating technological progress. The dissemination of such open platforms and many other similar information systems is still in infancy. Therefore, research is necessary because it enriches the understanding of the maritime sector that influence the communication and information sharing in the cross organizational information systems in this industry. The overall aim of the thesis is to understand the stakeholders’ attitudes to the maritime open innovation platforms especially on the needs and expectations of platforms. Also, to detect the barriers of maritime-related platforms and further give policy implications on the developers of platforms. Based on current research on innovation eco systems analyze a case OIP from a stakeholders’ perspective thereby identifying strengths and weaknesses to recommend general changes to the case OIP, both functional and strategic.
- PostAttaining important ERP upgrade factors: A case study of an offshore company(2010) Martinsen, Håvard; Chalmers tekniska högskola / Institutionen för sjöfart och marin teknik; Chalmers University of Technology / Department of Shipping and Marine TechnologyThe research examines the underlying reasons for a specific ERP upgrade project. Next, it examines the factors that facilitated the project’s success. A case study design was adopted to investigate the ERP upgrade project. Qualitative data collected through seven interviews were coded and analyzed. The findings indicate that the five themes; project management, communication, user involvement, external and internal support are correlated with the project’s success. Furthermore, it proposes that there are several different critical success factors in each project phase. The companies in this study wanted to remain anonymous in order to protect its business interests. The company that conducted the ERP upgrade project has been designated Company X. The company that provided the ERP system has been designated the ERP vendor.
- PostAutonomous and remotely operated service operation vessels in wind farms: A study exploring the practical utilization of autonomous and remotely operated service operation vessels during dynamic positioning operations in offshore wind farms.(2023) Degrell, Fredrika; Chalmers tekniska högskola / Institutionen för mekanik och maritima vetenskaper; Chalmers University of Technology / Department of Mechanics and Maritime Sciences; MacKinnon, Scott; MacKinnon, ScottIn response to the societal pressures for developing green energy sources to address the wicked problems of climate change, the maritime sector has witnessed a rapid development of offshore wind farms, particularly in Northern Europe. Part of the operational strategy to improve the opportunities for exploiting wind-based energy harvesting, are investments in digitalization and increasing levels of autonomous technologies. To maintain a safe and reliable operation and environmental protection it is critical that these technologies can be managed by human operators. This thesis examines the practical deployment of automation-based technology during dynamic positioning operations within wind farms according to dynamic positioning operators. An ethnographic study was conducted to map goal-based tasks during dynamic positioning operations within a wind farm. Dynamic positioning operators were requested to reflect on the practical possibilities of deploying automation-based technology to improve or substitute DP tasks during semi-structured interviews. One researcher and three developers within autonomous and remote steering were also interviewed using a semi-structured approach to obtain their take on human-machine interaction issues. A thematic analysis of the interviews detected the main attributes of tasks that could be allocated to autonomy or remote handling respectively. These findings were compared to previous research and deliberated in the discussion section. When human life is at risk, the response time is limited, and the outcome uncertain a task was considered high-risk. Primarily, these are tasks conducted close to installations and tasks relating to emergency response. There are several methods and aids to improve human-machine interaction issues, enhancing the use of autonomous and remote operations within wind farms. Nevertheless, the specific capabilities of humans in what is defined as high-risk situations should not be undervalued. Therefore, high-risk tasks are only practically deployed to any other party than a human under the circumstance that there is a human on board the vessel, monitoring with sufficient situation awareness and competence to take control when needed.
- PostBarriers and possibilities for inland waterways in Sweden - The fifth mode of transportation(2015) Arnholm, Maria; Leimalm, Madeleine; Chalmers tekniska högskola / Institutionen för sjöfart och marin teknik; Chalmers University of Technology / Department of Shipping and Marine TechnologyThe society depends on transportation, both for goods and passengers. The future increase of transport volumes in combination with limited capacity of infrastructure can therefore become problematic. The shipping industry has an unexploited capacity and inland waterways can thus contribute to a sustainable transport industry. The purpose of the study was to investigate the possibility of using inland waterways for transports in Sweden. The thesis was built upon an exploratory study in order to identify the barriers and possibilities associated with traffic under the new directive (2006/87/EG) on inland waterways in Sweden. Furthermore, potential benefits that could arise and to whom they could be accrued was investigated. In order to gain understanding and retrieve information on the topic interviews were conducted with different stakeholders. The result of the interviews showed that barriers were related to high initial costs, difficulties in minimizing risk and transport buyers’ resistance to change transport mode. Furthermore it was concluded that the risk of the new directive only becoming a change in theory, and not in practice increased the longer it took for traffic to start. The possibilities were found in the fact that there is increasing transport demand that the current infrastructure cannot handle, thus new solutions have to be developed. Political decisions in terms of competition for different transport modes could also provide incentives for transport buyers to investigate other transport solutions. Further the result showed that the public welfare in, terms of lower socio-economic costs and less impact on the environment, would benefit from a shift to transporting cargo on inland waterways in Sweden. The study does not provide any comprehensive investigation of the new directive on inland waterways. Nor has any calculations regarding profits and costs been performed.
- PostBenchmark for Reduction of Anchored Vessels Emissions Enabling Change of Operations - Research on air pollution management in The Port of Gothenburg, Sweden(2021) Florez, Carlos; Betancur, Valeria; Chalmers tekniska högskola / Institutionen för mekanik och maritima vetenskaper; Salo, Kent; Malmgren, ElinWhile air emission inventories can be calculated for distinct levels of accuracy depending on the availability of primary data versus average data, there are hovering assumptions in the methodologies that lead to uncertainties in assessing CO2 benchmarks for anchoring operational mode. Normally, well-grounded information is neither available for auxiliary engines nor boilers at anchor to estimate the fuel consumption and the CO2 emission that stem from it. However, research can generate primary data, as in the Brave Eco Method for tanker vessels. This case study creates a benchmark of CO2 emission for the vessel at anchor in the port of Gothenburg as well as qualitative information of energy management at anchor. The average CO2 emission rate for vessels at anchor in the port of Gothenburg was approximately 1.84 metric tonnes per hour in 2019. A similar emission rate is calculated for a period of 2021 with 1.54 metric tonnes of CO2 per hour. These emissions are calculated using a bottom-up and fuel-based inventory methodology consisting of estimating fuel consumption for all the port’s calls. Comparisons are made for world-known emission inventory methods in terms of CO2 emissions of the port calls. Spatial distributions of CO2 are shown for the designated anchor areas in Gothenburg. Ultimately, this research suggests a course of action to reduce carbon intensity in the areas adjoining the bay.
- PostBenchmarks and measures for better fuel efficiency.(2012) Wigforss, Johan; Chalmers tekniska högskola / Institutionen för sjöfart och marin teknik; Chalmers University of Technology / Department of Shipping and Marine TechnologyShipping will face an escalating competition in the future, as more stringent environmental regulations will lead to significant higher fuel costs. Today, the cost of fuel stands for approximate 35-70% of total operational cost. Fuel efficiency measures are vital in order to stay competitive in the future. The issue with the study is to examine how AIS data can be used to compare ships against each other with appropriate benchmarks in order to identify measures for better fuel efficiency. A case study of 44 general cargo ships was carried out with AIS data from 2010-2011. These were two sister groups of 7 700 dwt and 12 700 dwt, with 22 ships in each group. Each group of sister ships were selected from their design and configuration in order to eliminate any design configuration differences in the operational analysis. Disturbance in AIS data was corrected and only voyages with coherent data without time gaps were used in analysis. Ships in study show on a significant potential of improvement in terms of fuel efficiency. Short periods at high speed increase the average fuel consumption in total. All ships were operated at a significant higher average speed than the best economic speed, i.e. lowest cost per nautical mile. There were also tendencies of differences between the operators, where some operators tend to run their ships at a more fuel-efficient way than others. Capacity utilization analysis indicated a spare of 10-20% before hitting the optimum span, which show that fuel efficiency can be improved by increasing the output of the ships i.e. more cargo. However, the most important fuel efficiency measure is speed reduction, i.e. slow steam. The theoretical no anchoring strategy calculations confirm that there are great possibilities to minimize anchoring time in favour of speed reduction.
- PostBest Practices in near-miss reporting(2012) Erdoğan, Ilknur; Chalmers tekniska högskola / Institutionen för sjöfart och marin teknik; Chalmers University of Technology / Department of Shipping and Marine TechnologyThe ISM Code requires that hazardous situations are to be reported to the company, investigated and analysed in order to prevent future happenings. Near-miss reporting gains importance in this respect, because, near-misses are believed to represent experiences and mistakes that should be shared to learn from in order to prevent bigger accidents. However, the general belief is that near-misses are not reported at the level as expected by the authorities. Some studies have been carried out to find out main barriers to reporting. The main objective of this study is to find out some best practices about near-miss reporting from the companies that are active in Swedish and Finnish shipping industry and believed to have high level of safety understanding within their organization. In addition, external reporting systems such as Insjö and newly developing ForeSea have been investigated in this study. The study is based on interviews with a total of 32 representatives, both shore-based and ship-based, from four different companies. Also, one representative from Insjö has been interviewed. It is found out that the representatives from these companies claim to have progressed in achieving 'No-blame culture' within their organization. Besides, they have achieved to put a reporting system in use and try to make it work as good as possible. The representatives claim that they are interested in having a more international reporting system where they can share experiences. The providers of such systems try to improve their systems. However, the actual current benefit of a such system is unclear. The majority of the participants believe that near-miss reporting in principle has a significant effect creating and enhancing the safety culture. However, the actual benefits of the near-miss reporting are reported as being limited. Further, it seems that the companies are not yet utilizing the reported data for establishing trends to improve the follow-up and the awareness within the organization.
- PostBridging the gap: Aligning culture between ship and shore(2023) May, Philippa; Chalmers tekniska högskola / Institutionen för mekanik och maritima vetenskaper; Chalmers University of Technology / Department of Mechanics and Maritime Sciences; Lundh, Monica; Lundh, MonicaThis thesis aims to find strategies for, and barriers to, cultural alignment between ship and shore. The results of this research show that: (1) to align culture between ship and shore, an organization must adopt a culture based on people‐first values, holistic communication, low powerdistance, and two‐way trust; and (2) the main barrier to ship‐shore alignment is a culture that contains elements of hierarchy, patriarchy, autocracy, and disjointed communication. The cultural elements that were shown to support alignment were also shown to negate the barriers. These barriers were found in a literature review to be common descriptors of ‘how it is to work at sea’. Together these points exhibit the crux of the issue: that seafaring culture itself prevents alignment between ship and shore. In other words, cultural alignment cannot be achieved if seafaring culture is allowed to remain in its current state. The results therefore highlight its tremendously problematic nature. The need for a different style of leadership is growing in the maritime industry as the cultural gap persists between ship and shore. A transformational type of leadership based on trust, holistic communication and people‐first values will serve to both negate the problematic aspects of seafaring culture and align culture between ship and shore. This will make it possible for seafarers to work in a culture that benefits both them and maritime organizations, taking into account the modern world, its challenges of complexity and ever‐increasing requirements for intellectual diversity.
- PostBuilding Barriers, but for whom(2018) Cole, Sebastian; Winberg, Philip; Chalmers tekniska högskola / Institutionen för mekanik och maritima vetenskaper; Chalmers University of Technology / Department of Mechanics and Maritime SciencesThe impacts of the terrorist attacks on 11th of September 2001 in New York had a profound effect and the aftermath embraced universal consequences and repercussions. It was perceived by the International Maritime Organization and the European Union that similar attacks could be imminent and both bodies rapidly adopted new maritime and port security regulations to avert further events occurring. On a local level, the Member States of the two bodies had to develop their own national regulations. In this context, the thesis focuses on the barriers that Swedish port organisations have identified in order to comply with the regulatory security framework on a global, international and national level. Using a deductive approach, this explanatory case study is based on a wide electronic survey targeted at public port organisations in Sweden. The survey was based on the theoretical framework constructed. Furthermore, in-depth interviews were conducted with a wide range of special advisers and experts in the field of study. From this research, two main findings emerged; while the current regulatory security framework is sound, this still requires that all parties are actively involved. For all parties to be actively involved, the knowledge-creation and information-sharing must be improved on both an inter- and intra-organisational level.
- PostChallenges of achieving a high accessibility in remote offshore wind farms How will changing operational requirements affect access strategy during the operation and maintenance phase?(2015) Anderberg, Christopher; Chalmers tekniska högskola / Institutionen för sjöfart och marin teknik; Chalmers University of Technology / Department of Shipping and Marine TechnologyThe wind offshore industry has experienced a vast development since the start in the early 1990’s. At the end of 2013 there were 117.3 GW of installed wind energy capacity in the EU: 110.7 GW onshore and 6.6 GW offshore. A natural consequence of development offshore is a need for suitable vessels to undertake the assignments that arise from site development, site construction and further on to site operations and maintenance. During the operation & maintenance phase, which involves various support activities to carry out planned or unplanned maintenance, special designated Crew Transfer Vessels (CTV) conduct the majority of these. The tendency for wind offshore is to develop more and larger farms further offshore. There exists a need from many perspectives to develop and optimizing the access systems and the procedures around it in order to meet new operational demands for future wind farms. This thesis main purpose is to investigate how changing operational requirement in remote offshore wind farms will affect the safe and efficient transfer of personnel to wind turbines. To answer this, a qualitative research approach was selected where a mixed methodology was carried out involving on-bard observation on a real wind farm crew transfer vessel and through semi-structured interviews. Two main conclusions were drawn in the study. Firstly, the ambition for a high availability in remote offshore wind farms is crucial for the development and also to defend that push to be attractive in the future. The level of availability is dependent of an acceptable level of accessibility. Far offshore wind farms will require that the operational margins for crew transfer need to be increased in maintaining that. The limitations of the CTV’s can to some extent cover that and still remain safe and efficient, but an increased transfer time will limit that option. Secondly the SOV (Service Offshore Vessel) or other accommodation concept will cover the duties in working in rougher sea conditions however its efficiency in technician distribution needs to be increased if this should remain a cost effective solution.
- PostContainerized shipping via the northern sea route(2021) Citra, Rika; Ait, Mari-Liis; Chalmers tekniska högskola / Institutionen för mekanik och maritima vetenskaper; Ringsberg, Henrik; Ringsberg, Henrik; Li, ZhiyuanClimate change has enabled Arctic shipping, specifically with the Northern Sea Route (NSR) that connects the Eastern part of Asia with Northern Europe. Providing a shorter distance from Northeast Asia to Northern Europe compared to the Suez Canal Route (SCR), the NSR could potentially become an alternative route to the SCR. The shorter distance additionally brings savings in time, fuel consumption and possibly other areas of costs. The study results showed that with the container vessel voyage via the NSR, there is a reduction of 25.1% in total distance, 25.8% or around 7.4 days in journey time and significant reduction can be seen in fuel consumption (44.2%) when comparing the same port pairs against the voyage via the SCR. However, the potential usage of the NSR for container liner shipping does not come without its own set of disadvantages and challenges. According to the interviews conducted for this study, difficult weather conditions were the most prominent disadvantage that caused doubts for the professionals from the shipping industry. That followed by the concern about the infrastructure along the coast of the NSR, administrative and political issues and extra demands or costs related to the vessel operations. Additionally, the commercial usage of the NSR could be stunted as many major shipping companies and customer goods owners have signed an environmental pledge, i.e., the Arctic Shipping Corporate Pledge. According to the pledge, the signatory parties commit to not use the NSR in their commercial activities because of the sensitivity of the Arctic region, the fragility of its ecosystems and habitat. Regarding different stakeholders, the port authority has expressed a positive attitude towards developing the NSR and making it feasible for commercial activity due to their potential future gains connected to their advantageous geographical location. However, other stakeholders have shown more doubt about the actual practicability and success of the NSR as an alternative route to the SCR.
- PostConversion of ferries in the coastal areas: Towards a sustainable, accessible and integrated transportation(2023) Eliasson, Simon; Larsson, John; Chalmers tekniska högskola / Institutionen för mekanik och maritima vetenskaper; Chalmers University of Technology / Department of Mechanics and Maritime Sciences; Ringsberg, Henrik; Ringsberg, HenrikIt is important to consider the ferry transportation of passengers and goods in the rural coastal areas. There is a lack of research in the integration of passengers and goods in the rural areas. This has resulted in the thesis whose purpose is to explore how the integration of passengers and goods in the rural coastal areas in Bohuslän could be improved. This includes the accessibility aspect, both for passengers and the goods. Further, the purpose of the thesis is also to explore the potential renewable fuels that could be used onboard the ferries. The method that was conducted was a multiple case study with a mixed method approach. The case studies were conducted on different islands outside of Tjörn and Orust and were conducted to explore the current situations and the differences. The collection of data was both quantitative and qualitative data collected by observations, interviews and questionnaires. The collection of data resulted in a triangulation that enabled comparisons between the different data collections. The result showed that to increase both accessibility for passengers and goods, a floating pontoon together with hydraulic ramps could be used. It was found that if the accessibility for passengers increased, it could also lead to an improvement in the integration of passengers and goods. The design of the ferries needs to be developed to increase the efficiency of the integration of passengers and goods. Regarding the conversion to renewable fuel, the result showed that the best current solution would be to operate on battery ferries, together with a back-up system operating on HVO. An alternative to this could be to operate on a hybrid system with a smaller battery and HVO.
- PostCritical Success Factors in the Ship Brokerage Sector with emphasis on dry bulk in relation to ongoing trends(2015) Kleberg, Patrik; Dimitrios, Exameliotis; Chalmers tekniska högskola / Institutionen för sjöfart och marin teknik; Chalmers University of Technology / Department of Shipping and Marine TechnologyOngoing trends in the shipping industry have placed mid-sized dry bulk ship brokerage firms in dire straits. For one thing, the market share is divided to a reduced number of ship brokerage firms, in respect of mergers and acquisi-tions (M&A) and, for another thing, the considerable transparency due to the information flow has brought the antagonism a few quarters of a second away. Limited literature and studies exist in relation to this modern matter in the European shipping industry which this thesis makes an effort to cover with a qualitative study. In order for the investigation to have a more repre-sentative result, the investigation involves interviews of ship brokerage firms that are situated in the UK, Greece, and Sweden. In addition, since the main trends and obstacles are related to M&A and considerable flow of informa-tion, the investigation has adopted an angle towards business intelligence and information technology as well as change management. The outcome of this thesis is several critical success factors that could be applied on the dry bulk ship brokerage sector. These critical success factors are related to Kotter’s change management theory and Kelly’s network economy theory together with Bullen & Rockart’s perspective.
- PostDeveloping a KPI system for managing air emissions in a cruise company(2015) Krupp, Swantje; Cierpinski, Laura; Chalmers tekniska högskola / Institutionen för sjöfart och marin teknik; Chalmers University of Technology / Department of Shipping and Marine TechnologyAir pollution from cruise ships is receiving increasingly more attention. However, the management systems for emissions to air within cruise companies are still insufficiently developed, since the focus is on other environmental factors, such as garbage and wastewater. In order to enhance these management systems, this thesis is exploring a number of aspects that are intended to make air emission management in cruise companies more effective. In order to answer the defined research questions, semi-structured interviews as well as an industry benchmark have been chosen. These interviews have been conducted at a cruise company and at several external stakeholders. During the interviews it has been explored who the main stakeholders of air emissions from cruise ships are and what requirements these stakeholders have concerning air emission management. It has been found that the cultural background of a stakeholder is considered to have an influence on the priority with which environmental issues are perceived. Further, NOX, SOX, PM and CO2 have been identified as the most important pollutants, while NOX, SOX and PM being a problem on a regional basis whereas CO2 is considered to be a global problem. Further, the benefits and concerns related to the installations of continuous emission monitoring systems, that measure a variety of exhaust gases directly in the ship‟s stack and have recently been introduced for marine applications, are explored. This analysis has shown that a CEMS is an indispensable tool for effective air emission management in a cruise company, which provides a number of benefits to the company, given the fact that these systems can prove to operate in a marine environment. Finally, this thesis proposes a KPI system that considers the various demands of all stakeholders, in order to ensure that the data, which a CEMS provides is effectively used in order to ensure continuous emission reductions. The proposed KPI system uses a form of abstraction as well as a differentiation between a ship‟s operational modes in order to provide the KPI user with one single air emission KPI. These KPIs have been designed for each functional level within a cruise company.
- PostDevelopment and design of a ship model for use in education and research at Chalmers(2016) Bauge, Kjartan; Voraa, Emilie; Chalmers tekniska högskola / Institutionen för sjöfart och marin teknik; Chalmers University of Technology / Department of Shipping and Marine TechnologyIn this thesis a ship model for Chalmers University of Technology is developed. The model shall be used in research and education at the Department of Shipping and Marine Technology. The purpose was to develop a model that could compliment the courses thought at the maritime department at Chalmers, as well as the research. SSPA is maritime consultant company, ship model manufacturer and a test facility located in Gothen-burg, Sweden. Chalmers arrange yearly study visit to their test facilities as a part of the maritime educational program. These visits should complements the theoretical education and give the students hand-on experience. However, due to that most model tests are made confidential by the owner of the ship model, the students rarely get to participate in the model tests. For the same reason, the data from the tests are inaccessible and cannot be released to the students for further analysis. Therefor, Chalmers want to develop their own ship model. The thesis examines and describes the concept development, design of the hull and the design of the model itself. The report has been divided in three parts. The first part address the development of several concepts. It covers the investigation of the need for a ship model at Chalmers and the desired features the model should obtain. One concept is chosen and further developed in the next parts. The second part consider the design of the hull, and the third part cover the development of the model itself. The final result is 4.35 meter long ship model of a PCTC, which is specialised to do seakeeping and manoeuvring tests. In addition it has a large freeboard which makes it suitable to investigate intact stability.
- PostDigital Tanker Trade(2018) Kaber, Jacob; Kjellberg, Johan; Chalmers tekniska högskola / Institutionen för mekanik och maritima vetenskaper; Chalmers University of Technology / Department of Mechanics and Maritime SciencesThe technical advancements and digitization change the landscape of the shipping industry. An industry that has been considered slow-moving and conservative for ages, but slowly have started to see benefits of technological improvements such as Blockchain from the office side of the business. Money and valuable time could be saved due to improved processes but how does that affect the people within the organisation and the sales process? And what factors in the tanker market may affect the willingness to adopt new technological inventions? By using semi structured interviews to interview industry representatives from the maritime sector in Gothenburg, Sweden, the writers try to understand how the shipping business eventually will change in the five to ten years to come. The results show that Charterers are likely to do more fieldwork due to new technology that replace and change current work roles. Several interviewees emphasize that the business relations between Cargo-owners, Shipowners and Charterers are extremely important in the shipping industry and will likely become even more important in the future. Technology as Blockchain has also the positive impact of reducing financial risks for Charterers and Shipowners because of less need for Letters of Indemnity which has been a branch standard. It also increases transparency in the market, which was both negative and positive depending on where in the world the vessels from the company were trading.
- PostEmperor’s New Blockchain: An Overview of the Technology Adoption within the Maritime Industry(2019) Bunduchi, Doina; Chalmers tekniska högskola / Institutionen för mekanik och maritima vetenskaper; Ringsberg, Henrik; Ringsberg, HenrikPrior research on blockchain implementation in the maritime industry has praised the technology beyond its technical limitations perceiving it as a universal solution to overcome a myriad of problems. This thesis explores the blockchain technology adoption concerning the theory of mindfulness by presenting five blockchain use cases. Mindfulness implies that technology is thoroughly investigated when it comes to local contexts and alternative technologies, and it is adopted as the best task-technology-fit solution. However, the key findings in this thesis reveal that the adopters of the blockchain technology have little knowledge about what they are adopting or consciously adopting only the blockchain term and not much evidence of the technology itself. The findings from this study also contradict many exaggerated benefits previously attributed to the blockchain. This thesis dispels blockchain’s myth and stresses out the importance of adopting the technology deliberately for its merits and not based on its hype.
