Abstract [en]

This is a Master of Science thesis in Naval Architecture (course code SD271X). It was conducted at KTH Centre for Naval Architecture in collaboration with Wallenius Marine. The main objective of this master thesis project have been to evaluate the vulnerability for parametric rolling for 3 generations of Pure Car/Truck Carriers (PCTC's) from the Wallenius eet. This has been done by using IMO's current version of the second generation intact stability criteria for parametric rolling. The criteria is currently in a developement stage so focus has also been on evaluation of the criteria itself. The theory behind parametric roll and the IMO criteria is briey explained followed by results of assessment using the current criteria on the Wallenius ships.

When comparing the ships under similar loading conditions the conclusion is that the third generation PCTC is the most sensitive, the second less sensitive than the third, and the rst the least sensitive. This is shown through the results from the IMO evaluation and simulation results. After doing calculations on PCTC's the conclusion is that the present 7 speed methodology in the criteria for level 2 C2 is unable to capture sensibility ranking in a correct way.
