AbstractThis report describes the experiments carried out on a 1:29.69 scale fully appended model of the Preliminary Design of the Joint Support Ship (JSS) in the Oceans, Coastal and River Engineering (OCRE) Towing Tank in November - December 2011. The purpose of these experiments was to evaluate the performance of this design of the JSS in terms of its sea-keeping and added power in waves. Experiments were done at the End of Life (8.2 m draft) condition. Seakeeping tests in head seas were done at 12, 15 and 18 knots in sea state 5H, 18 knots in sea state 5 and in following seas at 15 knots in sea state 5. Added power experiments were done in head seas at 15 and 20 knots in sea state 3. Probability of slamming and propeller emergence was assessed at 18 knots in sea state 5 head seas. Roll, pitch and heave decay experiments were done to characterize the viscous damping of the ship.
