Wallenius Wilhelmsen has signed a letter of intent for four methanol-capable and ammonia-ready car carriers as part of its aim to offer zero-emission voyages for customers by 2027.

The LOI is for four 9,350-ceu vessels, plus individual options for an additional eight ships, to be delivered from mid-2026 by Jinling Shipyard in Jiangsu, China.

The car carriers will be build to a Deltamarin design and it is hoped that the LOI will be converted to a contract by the end of this year.
