Japan's K Line is taking a ship-by-ship approach to meeting the IMO's new rules on low-sulphur fuel.

CEO Eizo Murakami said on its website that the shipowner will use a combination of low-sulphur fuel oil, scrubbers and LNG to become compliant by the 1 January 2020 deadline.

Other alternative fuels could also be used.

"We will proceed on a ship-by-ship basis, aware that we cannot limit ourselves to one particular measure," Murakami said.
