Non-linear dynamic analysis of coupled spar platform
Journal of Civil Engineering and Management, 2013 Spar platforms are treated as cost-effective and resourceful type of offshore structure in deep water. With increasing depth there are significant changes in its structural behaviour due to coupling of spar hull-mooring line along with radical influence ...

Model test of new floating offshore wind turbine platforms
International Journal of Naval Architecture and Ocean Engineering, 2013 This paper presents the model test results of 3 new spar platforms which were developed based on the OC3-Hywind spar to support a 5-MW wind turbine. By changing the shape but keeping both volume and mass of OC3-Hywind spar platform, those platforms were ...
