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

Abstract

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 during its launching from ship in rough sea. This is a complex model which accounts for sea conditions as well as elasticity and damping properties of davit’s elements and mechanisms, rope and boat hull. Also, are presented results of example calculations for an assumed set of technical parameters of davit and boat as well as sea conditions.

Keywords:

ship in rough seas, life saving appliances (LSA), lifeboat launching, lifeboat motions, lifeboat launching simulation
