On June 10, 2020, Sinopec Corp. announced that the Jiangsu Rudong H5# offshore wind power project, undertaken by Shengli Oil Construction Company, had completed the 1250-ton offshore booster station jacket and successfully shipped to sea.

At the Longkou offshore engineering base, the jacket carrying the weight of the offshore booster station is up to 30.7 meters, with a total weight of about 1,250 tons. It is the "Dinghaishen Needle" in the sea and can bear the weight of the 3900-ton booster platform while supporting the booster station against high-intensity typhoons and tidal surges.

4 inclined leg truss structures, height 30.7 meters, total weight 1250 tons; a total of 4 steel pipe piles, a single height 84.3 meters, a single weight of about 188 tons, which is equivalent to the weight of more than 200 cast adult elephants. To slide this "big guy" onto the ship, it used a 12,000-ton final assembly slipway. The prefabricated modules for offshore steel structures completed over the years were all slipped from this slipway. Prior to this, the tide water level and the docking adjustment of the barge must be accurately calculated. Under the towing of the large hoist, the "tall" "guy" obediently slipped into the ship's track.

However, due to the impact of the new coronavirus pneumonia at the beginning of the year, the overall plan of the Rudong H5# project was greatly restricted. Many professional construction teams such as installation, electrical, anti-corrosion, fire protection, etc. cannot resume work on time, and material procurement and other matters are imminent. In order to break the on-site shutdown situation, the project department took the initiative to attack, on the one hand, it urgently integrated with local and oilfield epidemic prevention and control departments, on the other hand, it communicated urgently with relevant units such as owners, design, supervision, equipment manufacturers, etc., and considered the risk of delay at every level. , Come up with targeted solutions.

In addition to this, it must be foolproof in terms of safeguards. In accordance with the unified deployment of the "100 Days of Attacking and Creating Benefits" action, they actively carried out the labor competition of "Striving for Promoting Production and Management in One Hundred Days" and formulated "Three Major Implementation Plans", "Five Major Goals and Tasks" and "Seven Key Assessment Measures" ", set up an action leadership group and five professional assessment groups, carefully organized and steadily promoted to ensure the high-quality completion of on-site prefabrication.

With comprehensive security programs in place, it is necessary to increase the depth of prefabrication on the land and improve the construction efficiency of all employees. They coordinated and refined the actual situation of the Jiangsu Rudong H5# project, reorganized the construction plan according to the actual use of the Longkou site, and at the same time, the quality and safety management department paid close attention to the construction site and strictly controlled each construction process according to standards and specifications. Try to avoid the occurrence of rework and rework, which greatly improves the construction efficiency and shortens the construction time of the node. When hoisting, it is changed into a whole, which maximizes the use efficiency of various types of equipment, which accelerates the construction speed and saves the construction cost.

Jiangsu Rudong Offshore Wind Farm, where the jacket will be shipped and installed, is expected to begin offshore installation of steel pipe piles and jackets 60 hours after arriving at the installation site. This project is the first wind power project developed by Jiangsu Communications Holdings Co., Ltd. The successful completion of the project will lay a solid foundation for future cooperation with the company and diversify its "transportation + clean energy" and "combination of scenery and scenery" Indicate the direction of the development of chemical development, and promote the construction of "Strong, Rich and High" new Jiangsu process is of great significance.
