NYK develops Japan’s first VLSFO bunker fuel additive

24 May 2019

NYK and Nippon Yuka Kogyo Co. Ltd., an NYK Group company, have jointly developed Japan’s first additive for very low sulphur fuel oil (VLSFO) named Yunic 800VLS.

The patent pending fuel-oil additive improves safety by helping to avoid troubles that may be caused by certain contents of VLSFO.

Yunic 800VLS effectively disperses asphaltene and paraffin (wax) specific within VLSFOs to suppress sludge formation.

The effect of Yunic 800VLS has been certified by Nippon Kaiji Kyokai (ClassNK).

“A global sulphur cap will enter into force on January 1, 2020, and one way ships can meet the requirement is by using VLSFO (sulphur content below 0.5%),” explains NYK.

“However, a wide variety of VLSFO is expected to be supplied because the manufacturing process differs from conventional heavy fuel oil, which has a sulphur content up to 3.5%.

“NYK and Nippon Yuka Kogyo thus began examining VLSFO at an early stage and have developed an additive that will lessen the likelihood of the VLSFO causing engine problems, etc.”

Details about the product and certification can be found at the link below:
