Seakeeping analysis of two ships advancing parallel for underway replenishment

Zhongguo Jianchuan Yanjiu, 2017
Due to the wave and hydrodynamic interaction between two ships advancing parallel on the ocean, their six-degrees-of-freedom motions are much more complex during replenishment. The seakeeping performance of two vessels is analyzed with AQWA. On the basis
