An experimental investigation of hydrodynamic forces of cargo oil acting on the transverse bulkheads of oil tanker due to ship motions was carried out by a ship model equipped with oil tanks in waves.The main purpose of this investigation is to examine if the linear superposition principle can be applied or not to the response of hydrodynamic forces of cargo oil on the transverse bulkheads to a seaway.The ship model was a type of T-2 tanker, which was 4.5 meters in length and equipped with two sets of oil tanks, one at fore body and the other at midship. Dynamic forces on the transverse bulkheads and motions of the self-propelled model in regular and irregular waves are measured.From these experiments are reached the following conclusions.(1)It is found that the linear superposition principle is not applicable to the response of dynamic forces on the transverse bulkheads of oil tanker to a seaway. It seems, however, that this conclusion is premature, because the experiment procedure was not satisfactory enough to accomplish the purpose.(2)Either in regular waves or in irregular waves, dynamic forces on the transverse bulkheads are larger at bow than at midship.
