Navigational Improvements Through the Use of Maneuvering Propulsion Devices

Abstract

it is becoming increasingly difficult to maintain navigational control of large ships when they are maneuvering at low speeds. These difficulties stem from the pressures of increased channel traffic, the desire to reduce transit time, and the increasing physical dimensions of ships in relation to their waterways. In order to help alleviate these operational problems, many operators are increasing their interest in the application of bow thrusters or maneuvering propulsion devices (MPD) to both new and existing ship types. This paper aims to demonstrate the potential improvement in navigational maneuvering control possible by the application of maneuvering propulsion devices.
