Development and design of a ship model for use in education and research at Chalmers

Abstract

In 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.
