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 ...
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.
A new plan to manage the waste must be found and ships must be encouraged to use the port reception facilities rather than to discharge waste anywhere in the ocean. [4] As a response, the European Community adopted the Directive 2000/59/EC on port reception facilities with the goal of eliminating discharges of ship-generated residues into the ...
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 ...
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.
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.

A cruise home port is the port where cruise ship passengers board (or embark) to start their cruise and disembark the cruise ship at the end of their cruise. It is also where the cruise ship's supplies are loaded for the cruise, which includes everything from fresh water and fuel to fruits, vegetables, champagne, and any other supplies needed ...
