..., and then for the combined process. The two vessels were a turret-moored production ship of 230m length, and a four-column deep-draught floater (DDF) , the latter being a very large semi-submersible type structure. This paper concentrates on the analysis of the deep-draught floater. Standing (1990) provides further details...

.... This paper describes the equations of motion, and discusses the importance of the inertia coupling moment for a supply vessel and a production ship. Since their bodies are large compared to the wave amplitudes, the dynamics of these structures is modelled by frequency-dependent hydrodynamic coeffici ents. 1...
