Study on spm mooring system for side-by-side two vessels
Additional Document Info
In this paper, a new side-by-side mooring bay designed by Keppel Offshore & Marine Technology Centre is investigated, and its global performance and dynamic stability are compared against those of the traditional SPM-mooring system. The multi-body systems include SPM buoy with a turntable and mooring system, a VLCC FPSO, oil tanker, and the hawsers/fenders and yokes between them. A time-domain vessel-mooring-coupled dynamic analysis computer program is used to simulate their respective responses and relative displacements in collinear, relatively mild random wave and current environment assuming that the system is to be operated in a protected bay area. In the analyses of both systems, time-domain results of the responses, the corresponding spectra, and the summary of statistics are presented. It shows that the newly-designed SPM mooring system experiences smaller relative motions between vessels and is more stable in the same environment compared to the traditional SPM mooring system.
