Giant Japanese owner K Line is throwing its weight behind an AP Moller-Maersk-led bid to build an ammonia bunker tanker fleet.

The consortium has also brought the Maritime & Port Authority of Singapore (MPA) on board to help develop terminal infrastructure for the zero-carbon fuel.

The study group was formed last year by Danish container line Maersk and the Maersk Mc-Kinney Moller Center for Zero Carbon Shipping, together with Fleet Management, Keppel Offshore & Marine, Sumitomo Corp and class society ABS.
