Shore power, in the maritime context, is an essential term that references the power supply given to a boat, ship, or any other maritime vessel when it’s docked at the port. This system allows the ship's electrical equipment and machinery to function without using the ship's own generators, minimizing resources like fuel and reducing environmental pollution.

The term shore power is not unique to the maritime industry; it is also utilized in the world of road vehicles, specifically in transport trucks when they are parked. Trucks equipped with a shore power system can plug into an electrical power source when parked, allowing the driver to use electricity without running the truck's engine. In both maritime and transport application, the principle is to provide an external power source to stationary vehicles or vessels, reducing fuel consumption, engine noise, and air pollution.

Shore power can comprise both Alternating Current (AC) and Direct Current (DC). AC shore power supplies are more commonly used as most onboard systems and appliances typically operate on AC power. However, some ships may use DC power systems for certain functions. Regardless of AC or DC, the shore power must undergo a conversion process to ensure it matches the ship's onboard voltage. The goal is to provide a reliable power source that is compatible with the vessel's system, without disrupting the standard operating conditions.

The term Shore Power Only on a dock or port typically indicates that the boat or vessel should only use electricity supplied by the shore power connection, and not the onboard generator. It is often enforced in areas where noise control and air pollution are serious concerns, or at times when fuel conservation measures are in place. This addition to the base term 'shore power' denotes an exclusively external electricity supply to the docked vessel, alleviating any necessity to utilize onboard generators during the docking phase.

In sum, shore power is a critical system to maintain the operation of stationary ships or vessels while reducing the impact on the environment and conserving energy. It has gained significant importance as the maritime industry moves towards more sustainable and eco-friendly practices.
