NorSea Group and Siemens collaborate on shore power

(Stavanger 10.12. 2015) NorSea Group has signed an agreement with Siemens AG to investigate the basis for the establishment of shore power facilities at 6 supply bases in Norway. A realization of this project would involve significant environmental gains, including CO2 and NOx reductions, reduced noise level from the bases, improved energy efficiency and less burden on ships' power plants.

NorSea Group want to offer our customers an environmentally friendly energy alternative when docked, at our offshore supply bases in Norway. In cooperation with Siemens AS we are now investigating the basis for a standardized, modular concept for shore power which will trigger major environmental benefits locally as well as globally.

-Our shore commitment will, if realized, have substantial environmental benefits for the community and economic benefits for our customers through the reduction of operating expenses of ship machinery, reduction in fuel consumption (emission costs) and improved energy efficiency. We strongly believe that this is the future model for energy supply for ships in ports, says John Olaf Næsheim, Business Development Manager at NorSea Group.

Large environmental gains

For every kilo diesel consumed, emissions of CO2 from diesel can be multiplied by 3.17. If we estimate a consumption of 2 cubic diesel per day ashore for a supply vessel, a land power plant could reduce CO2 emissions by around 6 tonnes per day or more. (This applies in Norway where we have clean hydropower). In total NorSea Group has around 10,000 ship calls a year at their bases in Norway, which could potentially entail a reduction of 10 to 15,000 tonnes of CO2.

Shore power will also have local environmental benefits in terms of noise reduction to the bases vicinities. Noise from ports is a known problem in many communities along the coast and is something that NorSea Group has worked actively to reduce. Connected to shore power, engine noise from ships docked would be eliminated.

Demo Effect, both in Norway and internationally

Project cooperation is already underway and the parties are now working out a detailed design for each of the bases. Based on this design work, NorSea Group will apply Enova for funding for the implementation of shore power projects for all the bases under one. This will provide economies of scale in the development and a rational project from technical partner Siemens. By realization, a shore concept of this magnitude will have the potential of a "full-scale demonstration effect" in Norway and internationally. If we look at major port facilities in Asia or the United States, one might multiply the environmental impact by 20.

The way forward

If established, a shore power plant will involve a significant investment cost for the port's owner, but through public support and interaction with ship owners and operators in the oil and gas industry, NorSea Group hopes to get the project executed. We hope to have clarified the commercial decision-making in spring 2016, but we are dependant on getting Enova onboard with this project. The partners assume about 18 months project period to complete the plants. In the construction phase, Siemens will employ around 20 full-time positions in the Norwegian supplier industry.
