Computational model for simulation of lifeboat motions during its launching from ship in rough seas

This paper presents a computational model which describes motion of an object of six degrees of freedom(DoF), intended for simulation of spatial motion of one- or two- rope-sling lifeboat or rescue boat duringits launching from ship in rough sea. This is a complex model which accounts for sea conditions as wellas elasticity and damping properties of davit’s elements and mechanisms, rope and boat hull. Also, arepresented results of example calculations for an assumed set of technical parameters of davit and boat aswell as sea conditions.
