satamavirtojärjestelmät

Satamavirtojärjestelmät, often translated as port electrical systems or dockside power supply, refers to the infrastructure that provides electricity to ships while they are berthed at a port. This system allows vessels to connect to the shore-side power grid, eliminating the need to run their onboard diesel generators. The primary purpose of these systems is to reduce air pollution, noise, and vibration within port areas and surrounding communities.

When a ship connects to a satamavirtojärjestelmä, it can shut down its auxiliary engines, which are typically a significant source of emissions, including sulfur oxides (SOx), nitrogen oxides (NOx), and particulate matter. This also contributes to a quieter port environment. The technology involves specialized shore-side converters and onboard equipment on the vessel to ensure compatibility between the grid and the ship's electrical system. Various international standards govern the design and operation of these systems to ensure safety and interoperability.

The adoption of satamavirtojärjestelmät is driven by environmental regulations, the desire to improve port air quality, and the increasing focus on sustainable maritime operations. While the initial investment in infrastructure can be substantial for both ports and ship owners, the long-term benefits in terms of reduced fuel consumption, lower maintenance costs for onboard generators, and improved environmental performance are significant. Many ports globally are investing in or expanding their shore power capabilities to meet these environmental goals and enhance their attractiveness as sustainable shipping hubs.
