Japan’s MOL is among several Asian owners working with oil companies to jointly fund the ­installation of scrubbers to time-­chartered VLCCs, to comply with 2020 emissions regulations.

The moves, which involve retrofits of vessels already on the water, could provide a blueprint for owners that have long-term charter arrangements with local oil firms.

An agreement has reportedly been struck to retrofit several younger tankers in MOL’s fleet of 31 VLCCs, and the company is working closest with Japan’s leading refiner, the JXTG Group, market sources said.
