Japanese shipping giant NYK Line has completed what it says is the world's first methanol bunkering from a barge to a ship.

The Tokyo-listed operator said its owned 50,000-dwt chemical tanker Takaroa Sun (built 2019) took on the green fuel at Rotterdam on 10 May in a project led by the charterer, Canada's Waterfront Shipping.

The tanker is fitted with dual-fuel engines to run on methanol.
