The ABS-class suezmax tanker is being built at New Times Shipyard and complies with ABS Ammonia Ready Level 1 requirements indicating it is designed to be converted to run on ammonia.
It is one of a potential order for three tankers, and all three vessels, if built, was also meet ABS LNG ready requirements.
Patrick Ryan, ABS senior vice president, global engineering and technology, said: “Ammonia is a promising zero-carbon fuel that can help meet the IMO’s GHG reduction target for 2050. It offers shipowners and operators a zero-carbon tank-to-wake emissions profile but is not without challenges, not the least of which is the greater prescriptive requirements for containment and equipment than most of the other alternative fuels under consideration.”
Michael Androulakakis, technical manager of Avin International, said, ““The shipowners, seeking early carbonation of their fleet, which LNG fuel operations alone are not enough to fully achieve, have additionally invested in making the vessels ready for ammonia fuel. This currently appears to be one of the most widely available and most promising carbon neutral fuels for the future.”
Stena Pro Patria will be the first of three methanol vessels to be built by the joint venture between Swedish Stena Bulk and the Swiss-based Proman Shipping.
The steel cutting for Stena Pro Patria took place at China’s Guangzhou Shipyard International (GSI), with the shipyard set to further build two more sister ships for the joint venture firm: Stena ProMare and Stena Prosperous.
“The steel cutting for Stena Pro Patria is the first step in a fascinating series of projects that will further strengthen Stena’s commitment to sustainability excellence and with spearheading shipping’s fuel innovation and wider decarbonization journey,” said Erik Hanell, president and Ceo of Stena Bulk.
As a new methanol-ready tanker, Stena Pro Patria will benefit from several design and technical improvements to optimize energy and fuel efficiency. Additionally, the vessel’s latest generation MAN dual-fuel engines will also feature revolutionary new water and fuel emulsion technologies to significantly reduce nitrogen oxide (NOx) emissions.
Stena Pro Patria will use approximately 12,500 tonnes of methanol as fuel per year, which will significantly reduce the volume of carbon and greenhouse gas emissions resulting from the vessel’s commercial operations, especially compared to the use of conventional marine fuels.
Anita Gajadhar, managing director of Pro-man Shipping, said the new vessel signifies a “step closer towards reaping the benefits of methanol as a future-proof marine fuel and, in doing so, driving the transition towards more sustainable shipping worldwide.”
