Offshore piled wharves are usually connected to land area by approach bridge. The approach bridge structure isgenerally of high pile beam and plate type, and the superstructure forms the bridge deck system by erecting prestressed T beams. Due to the characteristics of a large weight and long span, the T beams are usually installed by crane ships. Therefore,the construction cost and safety risk are high. For Indonesia Shenhua Guohua Java 7 Power Plant Project, the maritime nonrotating synchronous double hoisting technology was applied to install T-beam. During the hoisting process, the lifting distance was adjusted by the ups and downs boom to control the installation position of T -beam, which effectively reduced the construction safety risks. It is the first application in the industry, and has achieved good economic and social benefits, which provides a reference basis for similar engineering construction. [ABSTRACT FROM AUTHOR]
