A ship equipped with tunnel thrusters, indicated by the circled "X" markings above the water line. Manoeuvering thrusters (bow thrusters and stern thrusters) are transversal propulsion devices built into or mounted to either the bow or stern (front or back, respectively) of a ship or boat to make it more manoeuvrable.
Repairs being performed on the bow thruster of the Bro Elizabeth. Positioning thrusters come in applications, Bow thrusters at the forward end of the vessel, and stern thrusters mounted aft on the boat. Their purpose is to maneuver or position the boat to a greater precision than the propulsion device can accomplish.
Azimuth thruster, pod underneath a ship, instead of a propeller and rudder; Bow thruster, or stern thruster, at the bow or the stern of a ship or boat; Rim-driven thruster, electric motor and propeller combined in single unit; Underwater Thrusters, electric motor or hydraulic motor and propeller combined in single unit to propel the ROV, AUV or UUV
A "ram" bulbous bow curves upwards from the bottom, and has a "knuckle" if the top is higher than the juncture with the hull—the through-tunnels in the side are bow thrusters. [1] A bulbous bow is a streamlined flaring or protruding bulb at the bow (or front) of a ship just below the waterline.
Hydraulic thrusters are mainly used on larger work class ROVs, mainly because they take up a lot of space and weight due to the extra components such as valves and pipes. [3] Hydraulic thruster technology is older than the electrical one, they are more rugged and their weight-to-thrust ratio is higher than electric thrusters, but maintenance ...
The Voith Schneider propeller was originally a design for a hydro-electric turbine. [2] Its Austrian inventor, Ernst Schneider, had a chance meeting on a train with a manager at Voith's subsidiary St. Pölten works; this led to the turbine being investigated by Voith's engineers, who discovered that although it was no more efficient than other water turbines, Schneider's design worked well as ...
Transverse Thrusters are installed in the bow or stern of a vessel in order to improve maneuverability. Depending on the type of vessel, the range of application for Transverse Thrusters extends from harbor maneuvering to positioning tasks offshore. The units can be installed either with a horizontal or vertical motor flange. [6] [10] [11]
Vertical transom and stern of a modern cargo ship. In some boats and ships, a transom is the aft transverse surface of the hull that forms the stern of a vessel. Historically, they are a development from the canoe stern (or "double-ender") wherein which both bow and stern are pointed. Transoms add both strength and width to the stern.
