The Effects of Bank and Shallow Water on theflow pattern around hull of LNG Carrier using CFD

Liquefied Natural Gas (LNG) tanker often travels through shallow waters with visible banks for its operations. Manoeuvring of vessel in restricted water is relatively difficult and exposed to higher risk level.Asymmetric flows around the ship when the ship travel close to bank may results in sway force and yaw moment on ship and because of the changing the velocity and pressure contours around the hull, lead to potentially dangerous situations. This research work will consider to behaviour of a LNG carrier in confined water taking into account the ship bank interactioneffects. Hull hydrodynamic forces and moments and ship-bank interaction affected on wake pattern around and behind the ship hull is investigated using computational fluid dynamic (CFD) and further validate by model test experiment that they have been performed in towing tank of Marine Lab. in University Technology Malaysia
