Effect on Ship Maneuvering Motion under Strong Tidal Current

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...

Speed Planning for a Maneuvering Motion

Collision-free motion among dynamic moving objects is an on-going research topic. Based on the concept of modified path-velocity decomposition, a strategy, the interface propagation method, is proposed for path planning in this paper. Since all global navigation paths are assumed to be planned already without any static obstacle in their paths. Each sub-task along the global path of each contro...

Tidal Effect on LNAPL Mobility

The tidal influence on LNAPL movement is a subject poorly studied with limited literature available. Tidal fluctuations along shorelines create a unique condition where the migration of LNAPLs is buffered and often mitigated from discharging into an open water body. A site investigation has been conducted in an area with presence of LNAPL located close to a major tidal river. The objective of t...
