Propulsion Rolls-Royce goes
electric Roll-Royce, Power Electric Systems Division has formally launched a means of converting existing diesel mechanical propulsion systems so that they can exploit more efficient electrical technology. Te conversion package is designed for the type of
platform supply ships, coastal vessels and offshore patrol boats that operate at low speeds or in standby mode. It uses Active Front End (AFE) frequency converters to control and make the shaſt generators (SG) into motors. Te shaſt generator, when used as an electric motor
will boost the vessel’s performance and energy efficiency. When less power is required, the main engine can be clutched free from the drive gearbox. Te frequency controlled SG will serve as the vessel’s main propulsion. Tis could also be utilised as a take–me–home safety device if the main engine were to fail. Previous installations have proven that zero pitch losses
and idle running of the main engines have been reduced by up to 90%, according to Rolls-Royce, and the return on investment has taken less than two years due to fuel savings and reduced maintenance. Trials of the new system have been carried out onboard the Norwegian Coastguard vessel Harstad.

Coatings Mercator gets
sleeker Mumbai-based Mercator Lines Limited is seeing the benefits of using International Paint’s fluoropolymer foul release coating, Intersleek 900, on the Aframax vessels Prem Pride and Prem Divya. Te vertical sides of Prem Pride were coated with
Intersleek 900 in October 2007. Te owner subsequently recorded a 6% reduction in fuel consumption, leading Mercator .to coat the entire underwater hull of Prem Divya during her second special survey in June 2008 with Intersleek 900. Now, Mercator has reported a 9% cut in fuel consumption for Prem Divya and, as a result, reckons to have reduced emissions to the environment equating to almost 11,000tonnes of CO2
, 100tonnes of SOx and
200tonnes of NOx. Contact International Paint Ltd, Stoneygate Lane, Felling,
