WÄRTSILÄ CLEANS UP FOUR KUWAITI VLCCS

Wednesday, May 13, 2020 

Wärtsilä has been contracted to upgrade the performance of four very large crude carriers (VLCCs) owned by Kuwait Oil Tanker Company (KOTC), a subsidiary of Kuwait Petroleum Company (KPC), by retrofitting the Wärtsilä Fuel Efficiency Boost solution to the ships’ main engines.

The modification will reduce fuel consumption, and correspondingly lessen the environmental impact, by lowering greenhouse gas emission levels. KOTC and other major ship owners who have taken a proactive approach towards environmental protection have been actively looking for ways to reduce fuel consumption and carbon footprint, thus paving the way for reduction of greenhouse gas emissions. As a result, Wärtsilä says its Fuel Efficiency Boost initiative has attracted considerable interest.

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 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.

“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 Riad Belaid, Area Sales GM, 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,” said KOTC Acting CEO, Ali Shehab.

The Wärtsilä Fuel Efficiency Boost 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%. The pilot installation showed around 10 to 12 t/day lower fuel consumption than a sister vessel operating the same route, and resulted in 1195t of fuel savings over the nine month pilot period.  

In 2019, Wärtsilä successfully installed the company’s Intelligent Combustion Control and Fuel Activated Sacless Technology (FAST) upgrades on these same four vessels.
