Hydrodynamic response of a non-ship-shaped FPSO vessel with damping plates

Abstract

Experimental and numerical hydrodynamic investigations were carried out on a 1:45 scale model of a novel non-ship-shaped floating, production, storage, and offloading (FPSO) vessel that has been designed for use in the icy waters of the Arctic as well as the severe sea states of the North Sea. This FPSO vessel has a turret mooring system that is disconnectable during emergencies and inclement weather conditions. Experiments were conducted on a 1:45 scale model of the FPSO with damping plates consisting of skirt plates and different sizes of keel plates in order to study their influence on the response of the vessel. A numerical study of the scale model was carried out using the Wave Analysis at Massachusetts Institute of Technology code, and the results provided by it were compared with those obtained from model tests in the wave basin.

Experimental Study on the Motion Response and Mooring Characteristics of a New Type Deep-draft Multi-column FDPSO

“…Taking into account the ratio of wave length to ship length is 0.5-2.0 and the ratio of wave frequency to wave length is constant, Munipalli [3] carried out the experimental study on the motion response under effect of weather vane for a FPSO with internal turret mooring system, which adopted 1:60 scale ratio. Vijayalakshmi [4] dealed with experimental and numerical computation analysis of the motion response of the FPSO of the floating tank bottom with additional horizontal damping plates. Soares [5] measured six degree of freedoms motion response and mooring force of a FPSO in regular waves and random waves by experiments, and the results calculated by Green function method are in good agreement with the experimental results.…”

Parametric Study on the Hydrodynamic Response of Dsi Polygonal Shaped Fpso

“…Goncalves et al [4] conducted experimental study on Vortex Induced motion (VIM) for monocolumn platform. Shen et al [8] studied the hydrodynamic characteristics of heave plates for Truss Spar; Experiments were conducted by Vijayalakshmi et al [14] to study the hydrodynamic response of the DSI FPSO vessel on a 1:45 scale model with damping plates (skirt plate and keel plates). Bin et al [1] numerically studied the damping effects on the Mathieu instability and the mechanism of Deep draft multi-spar (DDMS), a novel deepwater platform.…”
