Hydrodynamic interactions during launch and recovery of a small boat from a ship in a seaway: D69-46/2014E-PDF

"Wave-induced vessel motions often determine whether launch and recovery operations can proceed safely. For launch and recovery of a small craft from a larger ship, wave-induced motions of the larger ship will influence dynamic loads on the crane. The motions of the small craft will be a major determinant of the safety of onboard personnel. This paper examines wave-induced motions during launch and recovery, including the effect of hydrodynamic interactions between the two vessels. The presence of a larger ship is shown to have a major influence on motions of the small craft. Sample polar plots demonstrate the variation of relevant motion parameters with speed and heading, and can be used as the basis for operational guidance"--Abstract.
