en.Wedoany.com Reported - On June 2, the first vessel of the Seaspan 10K series methanol dual-fuel retrofit project, the "SEASPAN YANGTZE", was completed ahead of schedule at Shanghai COSCO Shipping Heavy Industry and successfully delivered for operation. This project is the world's largest independent container shipowner's first methanol dual-fuel EPC (Engineering, Procurement, Construction) turnkey project.
This marks another industry benchmark set by Shanghai COSCO Shipping Heavy Industry, following the delivery of the world's first methanol dual-fuel main and auxiliary engine retrofit project. According to the project manager at Shanghai COSCO Shipping Heavy Industry, the challenge of this retrofit lies in constructing a safe and reliable fuel tank. Utilizing the original ship's structure, a methanol storage tank with a capacity of 9,098.8 cubic meters was built through block construction by converting the original cargo hold. Additionally, by upgrading the original main engine components, the original fuel-oil-burning main engine was modified to burn both fuel oil and methanol.
Environmental benefits are one of the core highlights of this retrofit project. Using methanol as a clean marine fuel, the retrofitted "SEASPAN YANGTZE" achieves an EEXI (Energy Efficiency Existing Ship Index) approximately 55% lower than the Phase 0 (minimum energy efficiency standard) requirement, significantly surpassing baseline standards. Its energy efficiency level and carbon emission reduction potential have reached internationally leading levels, providing a replicable practical model for the green transformation of the shipping industry.
Compared to the 5- to 6-year construction cycle for new large dual-fuel container ships, the retrofit model of Shanghai COSCO Shipping Heavy Industry offers significant efficiency advantages. From contract signing to delivery, it takes only about 18 months, with approximately 15 months for major equipment procurement, during which the vessel can operate normally. The actual in-yard retrofit time is less than 3 months, greatly reducing downtime and lowering operational costs. This not only maximizes benefits for the shipowner but also provides an efficient and feasible "China solution" for the low-carbon transformation of global shipping.
As the first and only enterprise in China capable of implementing "ship-to-ship" bunkering of both LNG (Liquefied Natural Gas) and methanol, two green fuels, within a shipyard, Shanghai COSCO Shipping Heavy Industry has established a mature series of green energy retrofit solutions in the new energy field, with the capability to provide one-stop delivery services to shipowners worldwide. Through systematic retrofits of multiple series of methanol dual-fuel vessels, including 20,000 TEU (Twenty-foot Equivalent Unit), 13,800 TEU, and 10,000 TEU, as well as gas-in special survey repairs of several 23,000 TEU LNG dual-fuel container ships, Shanghai COSCO Shipping Heavy Industry has covered mainstream international LNG and methanol dual-fuel retrofit and repair scenarios, forming a replicable and scalable standardized model. This marks that China has acquired the capability for batch, standardized green retrofitting of large vessels.
