Finland: Wartsila to Deliver Design and Propulsion System for Trawler Gitte Henning

Wartsila has signed contracts for delivery of ship design and complete propulsion system for a large trawler, Gitte Henning, which the shipyard Western Baltija Shipbuilding in Lithuania is to build for the Danish fishing company Gitte Henning A/S.

The design contract includes all drawings and calculations that the shipyard requires to build the vessel. The propulsion equipment package include a Wärtsilä 9L32 main engine with new design, gear, controllable pitch propeller (CPP), HR Nozzle, Wärtsilä 8L26 auxiliary engine, as well as related equipment – including NOx reducers for both engines.

In addition to this Wärtsilä will also provide new building site supervision for the ship owner during the complete construction period for the vessel.

Compliant with IMO Tier II

To lower the emissions of nitrogen oxides (NOx), both engines are fitted with Wärtsilä’s NOx reducers (NOR). These are based on Selective Catalytic Reduction (SCR) technologies, reducing the NOx emissions by 85-95%. The NOR units are able to lower the NOx emissions to a level of 1.5 g/kWh. This is compliant with the requirements in IMO Tier III, which is expected to come into force in 2016

“One of our demands was that the new vessel would pass the IMO Tier III requirements. So with this new vessel we oblige future legislation and it fits our policy to be a sustainable company. Furthermore we save fuel with the total propulsion package”, says Henning Kjeldsen, owner of Gitte Henning A/S.

“We are very pleased that Gitte Henning A/S has chosen Wärtsilä as supplier of both design and propulsion system for the company’s new vessel. By combining our expertises we were able to offer a highly efficient and environmental friendly solution to meet the owner’s demands. This, in combination with a short delivery time, enabled us to win these contracts”, says Johan Hansten, Director Segment Sales, Wärtsilä Finland.

The fishing vessel is scheduled to be handed over to the customer at the end of July 2013. In operation the new Gitte Henning will fish in Danish and EU waters. The vessel is equipped to perform mid-water pelagic trawling, and has double trawl ways and 13 cargo holds that can carry a total of 3200 cubic metres of fish. The vessel will become the largest pelagic trawler in the Danish fishing fleet, and the third vessel with the same name that is owned and operated by the Danish fishing company. The previous Gitte Henning was also designed by Wärtsilä Ship Design, back in 2008.

“The next Gitte Henning will be a modernized and larger version of the ship the owner has today. The vessel is designed after specific requirements from the ship owner. In the new design both hull design and solutions on board are improved, with an overall goal to raise the environmental profile by reducing fuel consumption and harmful exhaust emissions. Wärtsilä has also optimized the ship design and propulsion solution to provide the fishing vessel with maximum bollard pull and best possible energy efficiency during trawling operations”, explains Ove Wilhelmsen, Managing Director Wärtsilä Ship Design Norway.

“Besides lower emissions and fuel consumption we have a top performing fishing vessel especially designed for mid-water pelagic trawling. Environment and performance are in balance “, says Henning Kjeldsen in Gitte Henning A/S.
