Moonpools are the openings through the hull of ships and offshore structures from deck to keel for safe and easy access to water. The large water column oscillation inside the moonpool affects the structure's motion and impacts workers' safety and the condition of equipment. DNV-recommended practice (2010) suggests that the fluid motion in the moonpool can be calculated by a radiation or diffraction panel program, but the viscous damping should be introduced.
