Gardar engine refit promises NOx and fuel savings
Wärtsilä is due to deliver the first of its new generation Wärtsilä 31 engines to a Norwegian customer, and this is the installation of such an engine to replace an older unit.
Owned by Gardar AS, the 1998-built Gardar has an 18-cylinder V-configuration Wästsilä 32 main engine that has worked hard over the years, and this will now be replaced by the 10-cylinder Wärtsilä 31 engine, which is also in a V-configuration, and which is seen as the world’s most effective medium-speed diesel engine.
As part of the package, Gardar will be installed with Wärtsilä NOx Reducer emission after-treatment system with a compact silencer, and the propulsion layout will also be upgraded.
The refit is expected to result in a reduction to the pelagic vessel’s annual fuel consumption of 200,000 litres, as well as making a significant difference to its environmental footprint with an annual reduction of 88 tonnes of NOx.
Lower fuel costs and NOx fees, combined with the longer service interval of the Wärtsilä 31 engine, is expected to result in significantly lower operating costs. The Norwegian NOx Fund has committed a substantial amount of support for this project, resulting in a very satisfactory repayment period.
“We are extremely happy to be able to make Gardar more ecologically sound. The investment in retrofitting the vessel will quickly pay itself back in terms of reduced fuel costs and NOx fees. We have been very satisfied with Wärtsilä’s engines and propulsions and consider installing NOx reducers to two more of our vessels,” said Christian Halstensen, owner and manager of Gardar AS.
“We could not be prouder of this agreement, as it shows responsibility from the customer and gives us the opportunity to contribute to more environmentally sound shipping, commented Cato Esperø, Sales Director at Wärtsilä Services.
“At Wärtsilä, we understand that a project like this is an investment financially, but it is also an investment in our future. We warmly support every action that goes beyond just meeting the environmental regulations.”
