ジャッキアップリグ用脚固定装置の設計について  [in Japanese] On the Design of a Leg Fixing Device for Jackup Rigs  [in Japanese]

Abstract

A leg fixing device, which connects together the leg and the hull of a jackup rig, is indispensable when the jackup rig develops oil and gas in harsh environment such as the North Sea, and it takes severe load through its several teeth in contact with the several teeth of the opposite leg rack. Accordingly, a design procedure for the leg fixing device is strongly needed. Nevertheless, classification societies do not supply adequate design guidance, nor report most of previous papers sufficient results. In this paper, based on the previous element strengths researches and newly added analytical results, a design procedure of leg fixing device, a simplified estimation method of load distribution among several teeth, a simplified estimation method of elasto-plastic root strain of a tooth with including the effect of friction and an optimization result of leg fixation device are reported.
