Numerical Study to Evaluate Course-Keeping Ability in Regular Waves using Weather Vaning Simulation

Since the introduction of mandatory energy efficiency design index (EEDI), several studies have been conducted on maneuverability waves owing to decrease in engine power. However, most used mean wave force during a single cycle evaluate and investigated turning performance. In this study, we calculated external accordance with angle incidence width wavelengths encountered by KVLCC2 (KRISO very large crude-oil carrier) operating at low speeds regular using computational fluid dynamics (CFD). We compare model test results those published other papers. Based CFD, an that varies according phase meets hull was derived, based derived MMG control simulation, maneuvering simulation constructed. Using method, weather vaning performed course-keeping ability waves. The confirmed there difference trajectory wavelength encountered.
