Electric Marine Propulsion Systems News

Corvus is a manufacturer of proven, high power Energy Storage Systems (ESS). Its field proven battery systems provide power to hybrid and fully electric marine propulsion systems. Founded in 2009, Corvus provides purpose-engineered ESS solutions for marine, oil & gas and port applications. Using a customer’s load profile, Corvus engineers design an ESS tailored to the customer application without the expense of custom engineering. The only purpose designed industrial lithium-ion battery system; it is scalable from 6.5 kWh at 48VDC to multiple Megawatt-hours and 1100VDC.

Rolls-Royce has announced its intention to acquire Scandinavian Electric Holding (SEH), a supplier of system packages for diesel-electric marine propulsion systems, continuing its growth strategy in the marine market. The acquisition, from Borea Opportunity II AS, requires approval from the Norwegian competition authorities, which is expected to be completed within a few weeks. Rolls-Royce will purchase 100 per cent of the equity of SEH for cash consideration of $84m. The company will form part of the Rolls-Royce marine business. The acquisition is consistent with the company's strategy of adding new capabilities and expanding into integrated power systems. SEH currently employs 150 people, in , , and , and recorded sales of £40 million in 2007 and has a current order book of £100 million.

Schottel ended the year 2003 with record sales. With 550 employees worldwide, the company continued the previous year’s trend, achieving sales in the new systems and service sectors totalling 90 million euro (2002: 81 million). Sales for the group were thus increased by 11%, and once again exports accounted for some 80% of the total. The extremely satisfactory volume of incoming orders in the last 12 months, amounting to some 88 million euro, means that 42 million euro of orders are on hand for the year 2004. Of particular significance are the latest worldwide sales successes in the areas of tug propulsion systems, offshore supply vessels, cruise ships, research vessels, ferries and military vessels.

After more than two years of development and successful performance trials at Howaldswerke-Deutsche Werft AG in Kiel, the Siemens-Schottel Propulsor (SSP) consortium was granted approval for the new SSP marine propulsion system. Classification society Det Norske Veritas was responsible for technical acceptance of the propulsion system for worldwide service. The SSP is the result of a successful cooperation between two German marine industry stalwarts, Siemens Marine Engineering Subdivision and Messrs Schottel of Spay. Work began in 1997 on the development of a marine propulsion "pod" system that would be offering not only economic advantages, but superior technological performance.
