Recently, our company successfully completed the roll on/roll off project of Yangxi Shapao Phase 345 offshore booster station, setting a record for the maximum roll on/roll off of a single offshore booster station.
The booster station weighs about 4200 tons and has a size of approximately 51.4 meters x 41.2 meters x 22.4 meters. Our company uses the 136 axis SPMT to transport the booster station from the construction site to the dock front, roll on to the deck barge, and place the booster station on the transportation fixture. The SPMT leaves the barge deck and exits the site. Next, it will be transported by the "Aohai Shenzhou" ship to Yangxi Wind Farm for installation.
The project has a tight schedule, heavy tasks, and a large weight of the booster station. During the roll on/roll off loading process, it is necessary to strictly control the ship's ballast water and combine it with tidal changes to ensure that the booster station can smoothly roll on/roll off onto the ship within the only 2-hour window period; The project department, through scientific planning and reasonable arrangement of preliminary preparation work, successfully loaded onto the ship. Using SPMT for transportation can effectively solve the limitation of manufacturing site size, and the transportation period is short. The transportation mode is flexible, which can ensure the short reverse loading of the dock front while manufacturing in the yard, and meet the construction period requirements for cross operations& The Three Gorges New Energy Yangxi Shaba Phase 345 Offshore Booster Station is currently the largest and largest installed capacity boosting station in China, and also the first boosting station in China to be equipped with three main transformers and three GIS high-voltage equipment. After the project is put into operation, it can save about 884600 tons of standard coal and reduce the emission of greenhouse gas carbon dioxide by about 2.41 million tons per year. This not only helps to achieve the economic benefits of saving coal and increasing electricity, but also promotes the optimization and transformation of energy structure.
