복합환경하중 조건에서의 해저생산플랜트 설치 작업 시뮬레이션 연구

Abstract

This study presents an numerical study on deep-water installation operation of subsea equipments under combined environmental conditions. Three simulation elements, that is vessel, body and link, are numerically modelling. The present numerical method is validated by comparing the simulation results with experimental data from model test. The comparison shows quite good agreement between the present simulation and experiments. In order to study the effect of wave depth and wave conditions, a series of numerical simulations were carried out. The performance of installation operation was checked through the vertical motion of the lifted equipment and dynamic tension on crane wire. The effect of current on equipment offset was also shown using the simulation results.ical method is validated by comparing the simulation results with experimental data from model test.
