A SEAKEEPING TEST ON A CONTAINER SHIP "AMERICA-MARU" ON THE NORTH PACIFIC OCEAN (PART 2)

In a previous paper, one of the authors reported the results of a seakeeping test on a container ship "America-Maru" of Mitsui O.S.K lines Ltd. on the North Pacific Ocean on her 25th voyage. This paper shows the results obtained on the 26th voyage of the same ship. On the outward as well as on the homeward voyages, the ship encountered rough sea states more than Beaufort scale 8 for three or four days continuously. The maximum amplitudes of pitch and roll were 6.2 degrees and 19.9 degrees respectively, and that of the vertical acceleration at F.P. reached 0.79 g. The average sea margin calculated on the basis of fuel oil consumption on the outward and homeward voyages were 62.7 percent and 60.4 percent respectively. These results seem to validate the correctness of the sea margin (60 percent) estimated at the initial design. In Japanese.
