On March 29, “Sanhang Xiang’an”, China’s first 5,000-ton luffing pole dynamic positioning crane vessel invested by CCCC Third Harbor Engineering Co., Ltd., was launched in Taizhou, Jiangsu Province, marking the crane vessel fully into the lifting boom installation, equipment commissioning tasks stage, to provide a solid foundation for the smooth commissioning of the vessel.
In order to cope with the development trend of offshore wind farms and large-scale units, “Sanhang Xiang’an” integrates today’s advanced technological achievements and intelligent means. And it is the first large-scale luffing pole dynamic positioning crane vessel in China with the ability of DP power positioning operation, which can meet the needs of mooring and power positioning lifting operations in the deep sea, and has a broad market application prospects.
“Sanhang Xiang’an” has an overall length of 178 meters, a beam of 48 meters and a depth of 13.5 meters. Its transom is equipped with a 5,000-ton lifting capacity large-scale offshore crane with single jib with double hooks. The main hook has a lifting capacity of 5000 tons with a spread of 95 meters and a lifting height of 133 meters on the deck, while the secondary hook has a lifting capacity of 1200 tons, with a spread of 109 meters and a lifting height of 150 meters on the deck, which is equivalent to the height of a 51-storey building.
The excellent lifting capacity makes this crane vessel has the leading advantage in the same industry in the field of offshore wind power pile foundation construction, large-scale booster station lifting, large-scale offshore component installation and deep-sea wind power field construction.
“Sanhang Xiang’an” is equipped with 3 sets of 2,500kW full rotary electric main propeller on the stern and 2 sets of 3,000kW side propellers at the bow as well as 6 anchoring systems, which effectively improves the efficiency of the crane vessel during the valuable window period by adopting the dual mode of “power positioning system + anchoring system” to carry out the lifting and installation of the large offshore components.
As a new generation of environmentally friendly, energy-saving and intelligent crane vessel, “Sanhang Xiang’an” conforms to the development trend of greening and intelligentization of offshore engineering vessels, and is designed and applied with intelligent motor monitoring system, which can greatly improve the utilization rate of energy. Also, the crane vessel adopts the offline insulation monitoring technology, which further improves the safety factor of the whole vessel through the intelligent monitoring of the important equipments on the whole vessel.
The ship-shore integrated comprehensive information management system configured on this crane vessel can meet the intelligent management of the whole vessel, integrating a number of functions such as checking the vessel’s position, alarm information of important equipments, video monitoring, energy-efficiency management, information of spare parts and certificates, management of personnel and oil information, etc. With this system, the shore-based management staff can grasp the vessel’s operation in real time.
