摘要

The objective of this paper is to make clear the difference of maneuvering characteristics of a VLCC in standstill from those of her in running.The authors made mathematic models to calculate maneuvering motions of a VLCC in standstill using various ahead engine with full rudder angle and calculated their motions in each case and compared the calculated values with those of the same vessel running in sea trial tests.The difference of motions between them is great.For example,a VLCC in standstill can achieve a great alteration of heading over 90 degrees within the distance of 0.2L advance while she advances 3.0L for 90 degrees turning in full running sea trial tun'ring test.Therefore whenever a VLCC in standstill meets a vessel approaching in collision course situation in near distance,it is better and recommendable that she should use her ahead engine with full rudder to avoid collision.So "maneuvering trial tests in standstill conditions" should be added to the content of sea trial tests when a newly built VLCC commence to take sea trials,that has not been included until now.
