Recently, the third methanol dual-fuel 15000TEU-class container vessel “CMA CGM CYRANO”, built by COSCO Shipping Dalian Shipbuilding Tianjin for the French CMA CGM Group, was named and delivered 13 days ahead of the contract schedule.
It is reported that the vessel has an overall length of 366 meters, a molded breadth of 51 meters, a molded depth of 30.2 meters, a design draft of 14.5 meters, and a structural draft of 16 meters. It is a mainstream vessel type in the current global trunk liner shipping market, meeting the International Maritime Organization Tier Ⅲ emission standards. It can flexibly switch between methanol mode and fuel oil mode, fully complying with current environmental emission standards for maritime navigation. The single vessel can reduce carbon dioxide emissions by approximately 120,000 tons per year, equivalent to the carbon sink effect of planting 6.7 million trees, making it a flagship product of green shipping.
During the construction of this vessel, Dalian Shipbuilding Tianjin achieved the first “methanol + fuel oil” combined sea trial. Drawing on the construction experience of the preceding vessels, the construction team planned in advance and moved the critical points forward, completing the inspection and acceptance of the fixed water monitor system, the grid connection and power generation of the shaft generator, and tests such as dead ship blackout recovery before the sea trial. All sea trial items were completed three days ahead of schedule, achieving a significant improvement in sea trial efficiency.
As of now, Dalian Shipbuilding Tianjin has completed the construction and delivery of three large methanol dual-fuel container vessels, forming a complete construction system from technology digestion and process optimization to sea trial organization and delivery management. In particular, the mature application of the “combined” sea trial mode marks that Dalian Shipbuilding Tianjin has entered a new stage of “rhythmic, high-efficiency, and standardized” production in the field of batch construction of green vessels.
