American Bureau of Shipping, CALAMCO, Fleet Management Limited, Sumitomo Corporation and TOTE Services, LLC have executed an April 2024 Memorandum of Understanding to jointly conduct a feasibility study to establish a supply chain for the provision of clean ammonia ship-to-ship bunkering in the US West Coast.

The study will be conducted at the Port of Oakland, Benicia and nearby major ports in U.S. West Coast.

CALAMCO is a California based cooperative composed of grower members, as well as the largest ammonia distributer in California. The study aims to explore possibility to utilize CALAMCO’s existing ammonia storage terminal at port of Stockton for a pilot demonstration project of ammonia bunkering for car carriers calling at port of Benicia and container vessels calling at port of Oakland as a first step toward wide adoption of ammonia as marine fuel in the US West Coast.
