Clean, renewable electricity from onshore means that Stena Line’s vessels Stena Germanica and Stena Scandinavica now can shut off their diesel generators during their stay at Port of Gothenburg. This pioneering project has gained a lot of interest among shipowners, ports and power utilities all over Europe.
“One important reason behind this interest is that we at ABB are pioneering a connection technology that converts 50 Hz – the standard AC frequency in Europe – to 60 Hz, which most vessels use as their system frequency, by the use of frequency converters. Furthermore, this is the largest shore-to-ship connection in terms of effect capacity in Europe ever so far,” said Ismir Fazlagic, product responsible for onshore connections at ABB.
The Gothenburg solution can therefore, also from an international perspective, imply a large-scale breakthrough for environment-friendly shore-to-ship power supply.
“The benefits are so obvious. As the diesel generators are shut off, CO2 emissions are reduced to zero when the electricity is generated from renewable sources like water, wind or solar power. During a 10-hour stay in port, the diesel generators of one single ship can produce 60 tons of carbon dioxide. In addition to this, onshore power supply means less noise in the port with surroundings and allows a more efficient maintenance of onboard equipment.
In many parts of the world, preparations are now at hand to make ports more environment friendly by using onshore power. A vital part of this process is to develop a common international standard for shore-to-ship connections.
“ABB is fully prepared with ready solutions according to the standard that is expected to come in 2011. Our conversion technology for high-voltage connection of ships with system frequency of 60 Hz is unique, now providing completely new possibilities for both ship owners and ports,” said Ismir Fazlagic.
The ABB delivery included, apart from design and commissioning, power transformers, frequency converters, medium-voltage switchgear, building, ventilation equipment as well as monitoring and safety equipment.
“We supply complete systems, optimized for efficient and sensible onshore connection of ships and based on module-based solutions. This means that they can easily be expanded, step by step according to the needs,” added Fazlagic.
In addition, the modular substations provide improved security as well as wind and weather protection. The design of the substation buildings can also easily be adapted to the surroundings and furthermore, the complete infrastructure requires minimal footprint on the dock.
ABB was the world pioneer in providing high-voltage power to ships via cable from the grid onshore. It was actually here in Gothenburg that the very first installation was made in 2000, which later helped Port of Gothenburg win two environmental awards: EU:s ”Clean Marine Award 2004” och Lloyd´s Lists ” Clean Seas Award 2008.”
