The dead weight of a power connection cable of a floating green-hydrogen production platform has a significant impact on the cable life. Increasing the floatability of this cable by attaching buoyancy modules to reduce its dead weight can improve its structural integrity. In this study, the effect of attaching buoyancy modules to the power connection cable of a floating green-hydrogen production platform was investigated. To this end, a coupled dynamic analysis was performed using the commercial software OrcaFlex. The production platform comprised a 15-MW floating offshore wind turbine (FOWT) and a floating production storage and offloading (FPSO) unit, connected by a power connection cable; buoyancy modules were attached to this connection cable. The environmental conditions were assumed to be the operating conditions, under which electricity was produced by the wind turbines. First, a static analysis was conducted, which confirmed that when the buoyancy module was attached, the effective tension of the connection cable decreased throughout the line. Next, a dynamic analysis to investigate the dynamic behavior of the effective tension and bending moment of the connection cable was also conducted. When a buoyancy module was attached to the connection cable, the effective tension was observed to decrease.
