Abstract:

For the purpose of environment protection and energy saving, reducing the ballast water technique was introduced to ship design, which caused the ship has new type section, such as ā€œVā€ type. It is necessary to research the hydrodynamics performance of the new type section ship before putting into use. In this paper, the research of the motion in wave has been carried out by strip method between the VLCC with new type section and the VLCC with normal section, thus a new type of VLCC section shape was optimized.The result of the checking calculations by three-dimensional time domain method based on rankine source and seakeeping model test showed that the calculation outcome and model test results was similar, so strip method can be used as a reliable and quickly assessment means to select the optimal case. The work in the paper supplied technology foundation for the practicability of the VLCC with new type section.
