Grieg Maritime signs contract for ammonia vessels

Grieg Maritime Group has contracted CSSC-affiliated Huangpu Wenchong Longxue yard for up to four ammonia-ready 82,300 dwt open hatch vessels.

No price has been revealed for the order, which includes two firm vessels with an option for a further pair. The first of the four vessels will deliver in the spring of 2026, with the following three throughout the year. All ships will be Norwegian-flagged, DVN-classed and meet the EEDI Phase 3 requirements.

Grieg Maritime Group said the 225 m long newbuilds will dwarf the 50,800 dwt L-class, previously the latest and largest vessels in its fleet. The units will be equipped with MAN B&W 5S60ME engine and prepared for tanks holding 3,000 m3 of ammonia on deck.

Internally dubbed “PulpMax”, the ship’s design has been developed with input from Grieg Shipbrokers and G2 Ocean, a joint venture between Gearbulk and Grieg Star.

Grieg Maritime Group is committed to the Norwegian Shipowner’s Association‘s climate targets, which include new ship orders only with zero-emission technology from 2030.
