A study on the simulation-based design technology of the subsea equipment using DIMS toolkit

Abstract

This paper concerns on the simulation-based design study for the subsea equipment using DIMS toolkit developed by KRISO & VM (Virtual Motion, Inc.) in Korea. Researches on the subsea equipment and system including deep-seabed integrated mining system are very difficult due to influences by high water pressure, extreme ocean environment and hydro dynamics. To tackle this problem, simulation-based research and engineering technologies are being actively studied and utilized inthese subsea R&D fields. Especially, dynamics-based simulation technologies are very important because the subsea equipment composed of several objects are installed and operated under various load conditions. For these reasons, Korean research team have developed the DIMS toolkit using multibody dynamics for the simulation-based research and engineering of the subsea equipment and system. The DIMS toolkit is developed as an add-on toolkit in ANSYS/Motion software. The DIMStoolkit can simulate not only the dynamic analysis of the equipments and systems but also the structural analysis, thermal analysis, and eigenvalue analysis of the equipments and systems because it shares the various analysis functions of the ANSYS software. So, we have used this toolkit for design of the subsea equipments in deep-seabed integrated mining system and various subsea systems such as offshore riser systems and ROVs.
