ABB Helps Stena Cruise Ships Use Shore Power at Home Harbor

A shore-ship power supply facility in the port of Gothenburg will use a substation provided by ABB, which, together with the facilities of Processkontroll Elektriska, will become the shore-powered infrastructure for Stena Line’s ships. Installation of the facility (reported to be the largest of its kind) has been completed and is jointly owned by Stena Line and the Swedish port.

ABB is responsible for the design, engineering, supply and commissioning of shore-based substations that provide 3MVA/11kV of power at 50Hz or 60Hz to the vessel. All equipment will include power transformers, frequency converters, medium voltage switchgear and monitoring/safety equipment.

During the 10-hour stay in Hong Kong, the cruise ship’s diesel generators can consume 20 tons of fuel and emit 60 tons of carbon dioxide (equivalent to the total daily emissions of 25 European midsize cars). In addition to reducing local carbon dioxide emissions, shore-ship power supply also helps reduce emissions of sulphur oxides, nitrogen oxides and particulates, lowering low-frequency noise and vibration in the port area, and the maintenance of the engine block while the ship is parked in Hong Kong. Maintenance work.

Oleg Aleinikov, head of ABB's substation facilities business, affirmed that "ABB is uniquely positioned to provide customers with turnkey projects for shore-ship power solutions by combining its ground-based power supply equipment and marine products and systems. We can provide a wide range of equipment in both power and automation, which allows us to provide the most optimized solutions for port authorities, shipowners and electricity users."

ABB provides onshore and onboard electrical equipment and systems for shore-ship electrical installations, including frequency converters, high- and medium-voltage switchgear, transformers, control and protection systems, as well as integrated systems and services ranging from the soon-to-be-started substations. Installation to the power system of the converted vessel to enable it to use shore-based electricity.

In 2000, ABB provided the world's first shore-ship power supply system to Gothenburg. The port was awarded the EU Maritime Cleaning Award for environmental responsibility in 2004 for reducing noise and gaseous pollutant emissions in Hong Kong.

The shore-based power supply of a ship or "cold-ironing", in order to be able to use shore-based power, the ship must invest in installing an additional power distribution screen, and the cable connecting the distribution board to the main power distribution screen, in most cases You also need a step-down transformer. The port needs to add a set of transformer devices, including high-voltage switchgear, a set of protection systems, a transformer, frequency converters, and communication equipment for contacting shore ships. In addition, cable handling systems are also required.

The general standard for shore electrical connection was jointly drafted by IEC ISO IEEE and approved in 2010.
