dc.description.abstractToday, the natural gas consumption is substantially increasing and the forecast for the future indicates that the consumption will keep on increasing. The result of this is that new innovative solutions are introduced to satisfy the demand from the customers. One of the latest ideas is to use a so-called FSRU GTW-unit, which is a floating unit that contains all the necessary process steps to produce electricity from LNG. This means that the unit will import LNG from a shuttle tanker and export electricity to shore. The objective with this thesis is to identify the hazards relevant to an FSRU GTW-concept and present requirements and recommendations. The hazards in question are those that can risk the safety of personnel, operability and structural integrity. The requirements and recommendations are based on an evaluation of how the hazards are addressed in existing rules and regulations provided by DNV and IMO. This can then be used as input to future rule development. In order to present relevant requirements and recommendations, it is essential to study existing rules in order to find what is applicable on an FSRU GTW-unit, and if there are any gaps or contradictions that need consideration. The rules and regulations that are thoroughly analysed are those provided by DNV and IMO. This analysis is preceded by a thorough study of related technologies and an evaluation of what hazards that are explicitly related to an FSRU GTW-unit. This is done according to IMO’s FSA-methodology with the aid of experts in the fields of electrical equipment, rotating machinery and offshore gas projects at DNV in Hövik, Norway. The FSA-methodology is a risk-based approach used for developing rules and the parts used in this work are those concerning the identification of hazards. It is concluded that there are contradictions and gaps in DNV’s present rules and regulations when applying these on an FSRU GTW-unit. It is, for example, stated by IMO in the IGC Code that boilers, machinery and such should be segregated from the storage facilities. This imposes a problem since the power plant, which consists of such equipment, will most probably be mounted on top of the storage tanks. Furthermore, there exist no explicit rules or design guidelines concerning electrical transmission through a turret. These kinds of contradictions and gaps show that there is a need for assembling various applicable rules and design guidelines together with additional requirements in a Classification Note for regasification vessels with power generation.
