In recent years, the International Electrotechnical Commission (IEC) has created a new standards suite for "Digital interfaces for navigational equipment within a ship". This is known as IEC 61162 and included NMEA 0183, NMEA 2000 and LWE. Additionally, different suppliers of marine electronics have their own communications protocol.
A submarine power cable is a transmission cable for carrying electric power below the surface of the water. [ 1] These are called "submarine" because they usually carry electric power beneath salt water (arms of the ocean, seas, straits, etc.) but it is also possible to use submarine power cables beneath fresh water (large lakes and rivers ).
The reduced weight and footprint of the installed electrical equipment will vary depending on the ship type and application. One comparison using the DC distribution system instead of the traditional AC system for a Platform Supply Vessel (PSV), reduced the weight of the electrical system components from 115,520 kilograms (254,680 lb) to 85,360 ...

Marine propulsion. Rolls-Royce Marine Spey, a gas turbine developed by Rolls-Royce Holdings in the 1960s for marine propulsion. Marine propulsion is the mechanism or system used to generate thrust to move a watercraft through water. While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical ...
Sustainable energy. Marine energy or marine power (also sometimes referred to as ocean energy, ocean power, or marine and hydrokinetic energy) refers to the energy carried by ocean waves, tides, salinity, and ocean temperature differences. The movement of water in the world's oceans creates a vast store of kinetic energy, or energy in motion.
