Seakeeping qualities of open-top containerships

Abstract

This paper presents the works carried out within the scope of the Applied Research Project entitled„Large Open-top Containerships”. The research and development part of the project was realized by Ship Hydromechanics Division (OHO), Ship Design and Research Centre (CTO) for the benefit of the Szczecin Shipyard. It concerned first of all the hull form optimization taking into account resistance/ propulsion as well as manoeuvring and seakeeping qualities of the ships. Structural calculations and design of certain on-board systems were also included into the project. This paper is focused on seakeeping qualities prediction based on model tests and numerical calculations of two ships. The tests were carried out in regular and irregular waves according to IMO recommendations concerning open-top containerships.
