Shore power or shore supply is the provision of shoreside electrical power to a ship at berth while its main and auxiliary engines are shut down. [1] While the term denotes shore as opposed to off-shore, it is sometimes applied to aircraft or land-based vehicles (such as campers, heavy trucks with sleeping compartments and tour buses), which may plug into grid power when parked for idle reduction.
The Massachusetts Port Authority carried out a study of cold ironing and alternatives in 2016 that pointed out a number of problems, including the high peak power demand (13 MW for a cruise ship, 3 MW for a container ship) and the high cost of providing the necessary equipment and upgraded electrical power infrastructure for Boston Harbor. It ...
A ship connected to the Port of San Diego's high-voltage shore connection, shortly after the port installed the connection in 2014. A high-voltage shore connection (HVSC) is an electrical connection between a ship and an electric grid, allowing the ship to shut off its engine and reduce fuel consumption and carbon emissions.
The port generally mandates a minimum horsepower or bollard pull, determined by the size of the escorted vessel. Most ports will have a number of tugs that are used for other purposes than ship assist, such as dredging operations, bunkering ships, transferring liquid products between berths, and cargo ops.
It can be used for any electrical ship application up to 20 megawatts and operates at a nominal voltage of 1000 V DC. The DC distribution system is simply an extension of the multiple DC links that already exist in all propulsion and thruster drives, which usually account for more than 80 percent of the electrical power consumption on electric ...

Bollard pull is a conventional measure of the pulling (or towing) power of a watercraft.It is defined as the force (usually in tonnes-force or kilonewtons (kN)) exerted by a vessel under full power, on a shore-mounted bollard through a tow-line, commonly measured in a practical test (but sometimes simulated) under test conditions that include calm water, no tide, level trim, and sufficient ...
While a reefer will have an integral refrigeration unit, they rely on external power, from electrical power points (“reefer points”) at a land-based site, a container ship or on quay. When being transported over the road on a trailer or over rail wagon, they can be powered from diesel powered generators ("gen sets") which attach to the ...
