Estimation of Position-Keeping Ability of an Offshore Platform for SMS Mining

熱水鉱床開発用プラットフォームの位置保持性能評価

In 2010, National Maritime Research Institute (NMRI) developed an integrated design support system, called "Harmonic Design Tool", to construct offshore platforms that harmonize with safety, economical aspects, and environmental matters. Using this tool in the basic design phase of platform, the authors are able to propose, in consideration of its operation plan, an optimum hull size and the specification of equipment such as mooring system and Dynamic Positioning System (DPS), and to roughly estimate construction cost and other expenses. The safety of mooring system and DPS can be also evaluated with the tool. In this paper, the authors discuss the position-keeping ability of a ship type platform designed in 2009 for mining of SMS (Seafloor Massive Sulfides), and evaluate the safety of its DPS (Dynamic Positioning System) using the "Harmonic Design Tool". At the same time, based on the model test carried out under complicated environmental conditions at Ocean Engineering Basin in NMRI, the authors evaluate DPS capability of the platform, and the accuracy of the "Harmonic Design Tool" is also verified. Because these evaluations revealed that the basic design of the platform could be materialized, the authors report the results in this paper.
