Twelve tankers delivered to Maersk Tankers between 2005 and 2008 are planned to be equipped with 'blend on-board' (BOB) cylinder oil systems from Maersk Fluid Technology.
The upgrade will be carried out under the first volume order for SEA-Mate B1000 units.
Maersk Fluid Technology introduced a new version of its cylinder oil BOB system in the second half of last year. It was aimed at medium-sized two-stroke propulsion engines with a cylinder bore between 420mm and 680mm.
The vessels that will see the new version will include ten vessels equipped with Wärtsilä (WinGD) RTA and RT-Flex engines, with a bore between 580mm and 620mm, and two vessels with medium-bore engines designed by MAN Diesel & Turbo.
Maersk Tankers CTO Tommy Thomassen said: "With the flexibility of the B1000 Blending-On-Board (BOB) system from Maersk Fluid Technology, we get the ability to match our cylinder oil lubrication to the fuel sulphur.
"The BOB system is expected to facilitate up to 40% reduction of current lube-oil consumption, cleaner main engine system oil and fuel savings of at least 0.5% for both MAN Diesel & Turbo and Wärtsilä (WinGD) two-stroke engines. Investing in BOB allows Maersk Tankers to stay flexible and ready for future lubrication challenges."
The company said that retrofitting of on-board existing vessels with the ordered BOB systems will not be complex.
The systems are planned to be installed this year, without changing the schedule of the vessels.
Following the installation, the vessels will gain the capacity to blend between 30 base number (BN) and140BN cylinder oil by using the in-use system oil as a base-oil.
The system is fully approved for the MAN Diesel & Turbo and Wärtsilä (WinGD) engines.
