On February 26th, Shanghai Zhenhua Port Machinery (ZPMC) held the delivery ceremony for the 3,600-ton full rotation crane vessel “Dianjian Zhigao” and the 1,600-ton self-propelled jack-up offshore wind power installation platform “Dianjian Zhiyuan”.
The 3,600-ton full rotation crane vessel “Dianjian Zhigao” has a length of 182 meters, a width of 49 meters, and a depth of 15 meters. It boasts a maximum lifting capacity of 3,600 tons (fixed stern crane) / 3,000 tons (full rotation) and a lifting height of up to 130 meters above the deck. It is suitable for the construction of 25 MW offshore wind power foundations (including jackets), installation of booster stations, and lifting of large marine structures.
The vessel’s hull adopts streamlined design and is equipped with an eight-point mooring and positioning system, which can realize high-precision operation in waters up to 100 meters deep and has the ability to navigate in unlimited navigational zones.
The vessel is independently developed by ZPMC from ship design to core equipment. It adopts an integrated information management system, which realizes the functions of unified portal system, ship and shore data synchronization, fuel monitoring and management, ship dynamic monitoring, equipment health assessment, ship management and crew duty behavior analysis, etc. The vessel is equipped with DP-1 power positioning system, which supports the vessel to adjust the position independently under complicated sea conditions, and improves the operation safety and efficiency. It also reduces energy consumption and meets Tier III emission standards.
The 1,600-ton wind power installation platform “Dianjian Zhiyuan” has a length of 123.95 meters, a width of 48 meters, and a depth of 9.5 meters, with a variable load capacity of 5,000 tons. The vessel is fully electric-driven, equipped with DP-2 dynamic positioning, and meets Tier III emission requirements, allowing for navigation in unrestricted international waters.
The front section of the platform features a helipad, and it is equipped with four truss-type legs, each 125 meters long, allowing a maximum working depth of 70 meters. The platform boasts high operational efficiency and precise positioning, making it suitable for installation operations in deep offshore wind farms and capable of accommodating the installation of wind turbines with capacities of 16 MW and above.
The successful delivery of the two vessels marks a significant collaboration between ZPMC and PowerChina in the field of offshore engineering vessels. The deployment of these vessels will greatly enhance PowerChina’s offshore engineering installation capabilities, providing crucial equipment support for China’s offshore wind power ventures into deep and distant seas.
