Model Test Report of a 50,000 Ton Heavy Lift Ship as a Seabased Intermediate Transfer Station

Abstract

A Center for Innovation in Ship Design model test was conducted to investigate the use of a Heavy Lift Ship as a Sea Base Intermediate Transfer Station (ITS). The ITS provides a platform whereby stores and equipment can be transferred from a large Ro/Ro vessel onto smaller transport vessels. This report describes the model tests conducted and the results obtained while analyzing the suitability of using a Heavy Lift Ship in this role. The testing showed a 30%-60% reduction in wave height within the lee of the HLS, depending on the sea state. No deck wash from the windward side was observed, however, testing in sea state 6 showed some limited 'scooping' of water by the deck edge on the lee-side of the HLS due to the increase in roll motion in higher sea states. Based on these results, it is suggested that the ITS configuration enables unlimited transfer operations in sea state 3 and possible operations in sea state 4.
