A Nonlinear Ship Manoeuvering Model: Identification and adaptive control with experiments for a model ship [PDF]
Complete nonlinear dynamic manoeuvering models of ships, with numerical values, are hard to find in the literature. This paper presents a modeling, identification, and control design where the objective is to manoeuver a ship along desired paths at ...

Numerical study on the 6-DOF motions of ship turning in waves [PDF]
Ships are often disturbed by waves when they are sailing on sea, and the influence is usually not negligible. When a ship is manoeuvering in waves, the wave will seriously threaten the ship’s navigation safety.

Intelligent Control for Ship Manoeuvering
In ship manoeuvering, the only two actuators are rudder and propeller revolution for the whole system. Therefore, by controlling these two for a designated purpose, automation in ship manoeuvering could be established. Classical control system like PID for track keeping or course changing has widely been used by on-board autopilot system.

Nautical Access Study Based On Real Time Bird’s Eye View Simulations [PDF]
Real time ship manoeuvring simulations are a valuable source of information in the detailed design phase of nautical studies. The feedback of pilots, which is not available for fast time simulations that are carried out by a computerized autopilot, is an

Numerical study on transient four-quadrant hydrodynamic performance of cycloidal propellers
Aiming to investigate the transient four-quadrant hydrodynamics on blades under the circumferential motion of the steering center, an efficient three-dimensional (3D) model with half blades was established in this paper.

Safer and More Efficient Ship Handling with the Pivot Point Concept [PDF]
The concept of the pivot point of a turning ship has been in existence for more than two centuries. It was not, however, properly understood from the beginning, and thus some misconceptions developed.

Risk Analysis on Ship Wreck and Container Cargo to Ship Navigation [PDF]
Wreck of a ship is an incident that must be avoided. Ship accidents are generally caused by a several cases, such as human error, natural disaster, technical errors, missed communication, poor condition of the ship, and many more. Ship wreckage have huge

Neuroevolutionary Approach to COLREGs Ship Maneuvers [PDF]
The paper describes the usage of neuroevolutionary method in collision avoidance of two power-driven vessels approaching each other regarding COLREGs rules. This may be also be seen as the ship handling system that simulates a learning process of a group
