해체 중인 고정식 구조물의 유체하중 해석기법 개발

Abstract

The present study considers the development of hydrodynamic solver on fixed platform during offshore decommissioning. The hydrodynamic solver was developed based on API and DNV recommended practices. Empirical formulations for inertial and drag coefficients were applied and corrections due to seabed and free-surface effects were made. The program was verified through several numerical tests and validated with CFD results on a simple structure. Additionally, an application to the jacket platform was presented.drag coefficients were applied and corrections due to seabed and free-surface effects were made.
