Marine technology group Wartsila and Italian classification society RINA have come up with a way to hit International Maritime Organization 2030 targets for cutting emissions.

The system involves using current four-stroke dual-fuel engines.

Installing two of the Wartsila 31DF engines, fuelled on LNG with electric power back-up for when the ship is idle, can lower a ship’s Energy Efficiency Design Index (EEDI) value by up to 50%.

It can also cut CO2 emissions by 40%, in line with the IMO 2030 target, the companies said.
