Effects of buoyancy tanks on offshore vessel stability

Siemens Digital Industries Software solution enables Twin Marine Heavy lift to predict complex phenomena. The Marine contractor uses Simcenter STAR-CCM+ to analyze the effects of buoyancy tanks on vessel stability. The presence of the buoyancy tanks, large blunt bodies at the side of the ship, would have a significant influence on the resistance and course stability during transport. Vortex shedding was certain to be an issue for flow analysis. In addition, the interaction between the buoyancy tanks and the ship’s hull was another problem to consider.
