Ship electric motor can be directly connected to the network, and such direct-on-line (DOL) motors are normally three-phase asynchronous, or induction motors. The ship asynchronous... Read more
The ship electrical motor is the most commonly used device for conversion from electrical to mechanical power on ship and is used for ship electric propulsion, thrusters for propul... Read more
The purpose of the ship transformer is to isolate the different parts of the electric power distribution system into several partitions, normally in order to obtain different volta... Read more
The main (or generator) switchboards are usually distributed or split in two, three, or four sections, in order to obtain the redundancy requirements of the vessel. According to ru... Read more
The majority of new buildings and all commercial vessels have an AC power generation plant with AC distribution. The generators are synchronous machines, with a magnetizing winding... Read more
The source for power is most often a generator set driven by a combustion engine which is fueled with diesel or heavy fuel oil. Occasionally one can find gas engines, and also gas... Read more
The main difference between the marine and a land-based electrical power system is the fact that the marine power system is an isolated system with short distances from the generat... Read more
Despite the great interest in the application of electric propulsion to warships, there are quite few conventional surface warships with pure electric propulsion, but more are bein... Read more
Diesel electric propulsion and station keeping facilities are also used in vessels for operations in more shallow waters, such as dredgers and construction vessels, wind mill insta... Read more
For vessels with dynamic positioning (DP) as the main operating mode, such as diving support vessels, crane ships, and pipe layers, electric propulsion was early taken into use, fi... Read more
