CTV から浮体式変電所への作業員移乗時に関する一考察

This paper presents an assessment of the performance a Crew Transfer Vessel (CTV) in transfer mode to floating substation using P-plot chart and discusses on influence motion characteristics CTV her horizontal fender force. The results suggested that there is almost no shielding effect structure at slip limit substation's small motion. In addition, difference characteristic due berthing direction small, value higher type than fixed substation. Three different joint's torsional stiffness around z-axis has been tried it found based only vertical joint force which implies symmetrical antisymmetrical motions are not coupled even when she berthing. On other hand, clearly appeared antisymmetric spectrum As result, generally considerable considering both forces except for stiffness. wave surface elevation rotation also discussed as factors.
