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 convention pertains specifically to a ship's load line, a marking of the highest points on a ship's hull that can safely meet the surface of the water; a ship that is loaded to the point where its load line is underwater and no longer visible has exceeded its draft and is in danger because its capacity has been exceeded.

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. [1] The ship can use electric power for its consumption of energy. They are mostly used in the cruise ships which dock for longer time and hence save ...
The Electric Reliability Council of Texas (ERCOT) manages the flow of electric power on the Texas Interconnection that supplies power to 26 million Texas customers – representing 90 percent of the state's electric load. [3] ERCOT is the first independent system operator (ISO) in the United States [4] and one of nine ISOs in North America. [5]
This externally sourced power serves the ship's internal cargo handling machinery and hotelling requirements. [jargon] Effectively, all the power generating sources are shut down and the ship is hence cold-ironed. This brings immediate relief from pollution by shipboard emissions and allows a more holistic maintenance schedule to be followed by ...
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.
Texas electricity generation by type, 2001-2024. This is a list of electricity-generating power stations in the U.S. state of Texas, sorted by type and name. In 2022, Texas had a total summer capacity of 148,900 MW through all of its power plants, and a net generation of 525,562 GWh. [2]
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 ...
