Ship Motion and the Dangerous Zone of a Ship in Severe Following Seas

Effects of Ship Motion on Ship Maneuvering in Waves

Ship maneuvering performance is typically predicted in calm water conditions. This provides very valuable information at the initial ship design stage. However, since the ship always sails in waves, the maneuvering performance of the ship in seaway may be significantly different from calm water condition. Therefore, if the effect of waves and the corresponding motion responses can be included i...

Ship Roll Motion Control

The technical feasibility of roll motion control devices has been amply demonstrated for over 100 years. Performance, however, can still fall short of expectations because of deficiencies in control system designs, which have proven to be far from trivial due to fundamental performance limitations. This tutorial paper presents an account of the development of various ship roll motion control sy...

Simulation of Ship Motion in Seaway

Accurate modelling and simulation of ship motion in seaway is essential to test applications of ship motion control strategies. In this report, we review the mathematical description of ocean waves, and their effect on the motion of marine vehicles. We present a simple method suitable for accurate simulation that incorporates parameters related to the recommended spectral family and particular ...
