Four vessels owned by Kuwait Oil Tanker Company (KOTC), a subsidiary of Kuwait Petroleum Company (KPC), will have their main engines retrofitted with Wärtsilä’s Fuel Efficiency Boost solution.
The modification will reduce fuel consumption and reduce the environmental impact by lowering greenhouse gas (GHG) emissions. The order with Wärtsilä was placed in the first quarter of 2020.
The Wärtsilä solution is based on two-stroke engine optimisation technology for selected Wärtsilä RT-flex and earlier deliveries of X-type two-stroke engines. The four KOTC very large crude carriers (VLCCs) to be retrofitted operate with 7-cylinder Wärtsilä RT-flex82T two-stroke main engines. The retrofitting of the vessels with the Wärtsilä Fuel Efficiency Boost will take place over the coming six months.
The Wärtsilä solution is a combination of an increased compression ratio and modified injector nozzles. Together with optimised engine tuning parameters, it allows fuel savings of up to 4 per cent. The pilot installation showed around 10-12 tons per day lower fuel consumption than a sister vessel operating the same route, and resulted in 1195 tons of fuel savings over the 9 months pilot period.
“Our smart marine approach is dedicated towards raising efficiencies and improving the environmental sustainability of marine operations. The Wärtsilä Fuel Efficiency Boost is completely aligned with this philosophy, while at the same time lowering operating costs,” said Mr Riad Belaid, area sales GM, Middle East & Asia, 2-stroke & specialised services, Wärtsilä Marine Business.
“By modifying the main engines of these carriers, we are assured of operating with the latest technology and having the best operational efficiency. We know and trust Wärtsilä’s high quality products and systems, and we appreciate the excellent support they offer,” stated KOTC’s acting CEO, Mr. Ali Shehab.
