On April 27th, CSSC Huangpu Wenchong Shipbuilding Co. Ltd. delivered the 1,600-dwt deep-water semi-submersible crane engineering vessel to Zhengli Ocean Engineering Co. in Nansha, Guangzhou. The new invention of the vessel also turned out to be the best souvenir that marked the ten-year’s anniversary of Huang Wenchong’s entrepreneurship in Longxue.
The detailed design of the specialized vessel is in the charge of Shanghai Merchant Ship Design and Research Institute. The vessel is unique in design and has achieved a major breakthrough in both technological and economical aspects. With many technical indexes reaching the world-top level and the comprehensive operating capacity ranking first in China, the vessel can fully meet the requirements of offshore engineering work such as offshore wind power, bridges, salvage, and etc.
It is reported that the vessel has such strong adaptability to complex marine geological condition on the seafloor that it can perform deep-water submersion work against wind of Beaufort force 9, and maintain good station keeping against a super typhoon of over Category 16, without needing to return to harbor for shelter. The 1,600-ton derrick crane equipped on the ship hoists from the center. The maximum height of the crane is 161 meters from the baseline, which is equivalent to the height of a building of over 50 stories.
The vessel’s main working deck covers a utilization area of about 3,000 square meters. With a variable load of about 4,000 tons, the largest deck can simultaneously load 2 sets of 10 MW fan parts and a complete set of piling equipment.
In recent years, China has witnessed the rapid development of offshore wind power industry. China’s 13th Five-Year Plan for Renewable Energy Development proposed that by 2020, the national offshore wind power capacity will be 10 million kilowatts. According to insiders, equipment products such as wind power installation platforms and engineering platforms for large-tonnage cranes have broad markets.
After the vessel is put into service, it will firstly be applied in the offshore wind power project in Dalian Township, Pingtan, Fujian Province, which will accelerate the construction of the project and improve the construction efficiency. In the future, the vessel is expected to effectively increase the construction capacity of offshore wind power and other offshore projects in China, serving as powerful equipment for China to develop its marine economy and to build itself into a marine power.
