In recent years, concerns about severe environmental pollution and fossil fuel consumption
has grabbed attention in the transportation industry, particularly in marine vessels. Another …

The control algorithm hierarchy of motion control for over-actuated mechanical systems with
a redundant set of effectors and actuators commonly includes three levels. First, a high-level …

Marine vessels with dynamic positioning (DP) capability are typically equipped with
sufficient number of thrusters to make them overactuated and with satellite navigation and …

For many offshore activities, including offshore oil and gas exploration and offshore wind
farm construction, it is essential to keep the position and heading of the vessel stable. The …

A dynamic positioning (DP) system on a diesel-electric ship applies electric power to keep
the positioning and heading of the ship subject to dynamic disturbances due to the winds …

In offshore maritime operations, automated systems capable of maintaining the vessel's
position and heading using its own propellers and thrusters to compensate exogenous …

Modern ships and offshore units built for dynamic positioning (DP) are often powered by an
electric power plant consisting of two or more diesel-electric generators. Actuation in any …

Abstract The Dynamic Positioning System is responsible for the station keeping of the vessel
in a variety of offshore operations. The thrust allocation algorithm distributes the required …

In this paper, a thrust allocation algorithm for marine vessels based on model predictive
control (MPC) theory and a nonangular vector formulation is presented and studied. The …

This paper is focused on the thrust allocation algorithm, which is a part of a Dynamic
Positioning (DP) system in marine vessels with diesel-electric power system. In this paper …
