ABSTRACT

In this paper, 2D and 3D green water on fixed ship in head-sea condition without forward speed are investigated numerically based on a parallel MPS solver, MLParticle-SJTU, developed in Shanghai Jiao Tong University. Two cases are considered: first, green water on 2D FPSO exposed to regular wave is analyzed. The shipping wave and impact pressure on a deck mounted structure are calculated and compared with experimental results obtained by Greco (2001) and numerical results computed by Nielsen (2004). Qualitatively and quantitatively, the agreement is good. Second, a 3D green water case is considered, where the incoming wave is a solitary wave with a large height, representing an extreme sea condition. Evolution of wave shipping on the deck is analyzed. Severe shipping water is observed. Under such circumstance, the structure on the deck is largely wetted and endures a large impact pressure. This 3D simulation suggests that the MLParticle-SJTU solver is capable of handling such 3D green water incident.
