In present work, a simplified methodology able to provide a sufficiently accurate assessment of wave drift forces is presented, with the aim of providing a procedure which may be applied in the preliminary stages of the design, when the technical data of the ship (such as the hull forms) are not yet available, and only main hull parameters are...

A simulation model of the DP system for a conventional naval configuration is presented. A complete mathematical description of the dynamically positioned vessel is developed, including distinct models for low- and wave-frequency ship motions, slowly-varying wind and wave forces, and mechanical constraints on the actuators. A specific...
