Large vessels sometimes use electrical propulsion motors, the electrical power being provided by a diesel generator. Noise and vibration of electric motors include, besides mechanical and aerodynamic sources, an electromagnetic source due to electromagnetic forces which is responsible for the "whining noise" of the motor.
Air-independent propulsion (AIP), or air-independent power, is any marine propulsion technology that allows a non-nuclear submarine to operate without access to atmospheric oxygen (by surfacing or using a snorkel). AIP can augment or replace the diesel-electric propulsion system of non-nuclear vessels.
The electrical power requirements of vessels are expanding as systems are expected to support power converters capable of integrating alternative sources and storage systems – including wind and solar power – and battery storage with a range of voltages, frequencies and power levels.
While smaller vessels tend to have a single screw, even very large ships such as tankers, container ships and bulk carriers may have single screws for reasons of fuel efficiency. Other vessels may have twin, triple or quadruple screws. Power is transmitted from the engine to the screw by way of a propeller shaft, which may be connected to a ...
A brushless alternator is composed of two alternators built end-to-end on one shaft. Until 1966, alternators used brushes with rotating field. [20] With the advancement in semiconductor technology, brushless alternators are possible. Smaller brushless alternators may look like one unit, but the two parts are readily identifiable in the large ...
For certain types of electric motors or generators to function, the coils of the rotor must be connected to complete an electrical circuit. Originally this was accomplished by affixing a copper or brass commutator or 'slip ring' to the shaft, with springs pressing braided copper wire 'brushes' onto the slip rings or commutator which conduct the current.
The Ship-to-Shore Connector (SSC), also known as the LCAC 100 class, [6] is a system proposed by the United States Navy as a replacement for the Landing Craft Air Cushion (LCAC). [7] It will offer an increased capacity to cope with the growing weight of equipment used by the United States Army and Marine Corps. [5]
Arab Shipbuilding and Repair Yard Company (ASRY), [1] (Arabic: الشركة العربية لبناء وإصلاح السفن) is a Multinational Arab company based in Al Hidd, Bahrain. [2] The company was founded in 1977, by seven OAPEC member countries: Bahrain , Kuwait , United Arab Emirates .
