The final stage of the project involved hooking upDiamond Offshore Drilling Inc.’s Ocean Victory semisubmersible drilling rig to the preset mooring spread InterMoor had previously installed, marking the completion of the company’s mooring and foundation installation campaign for BP Trinidad and Tobago’s (bpTT) Juniper gas project.
The hookup took less than four days and required 14 InterMoor personnel.
Before the hookup,InterMoor successfully completed a contract with bpTT, which included the initial design of a mooring system, the fabrication of driven piles, and the installation of a preset mooring spread. The company designed and fabricated eight piles (1.2 m in diameter by 39 m long, or 2.9 ft by 127 ft) at its Morgan City, Louisiana facility and provided offshore project management services for the mooring preset campaign. This included installing the driven piles using H-links and 300 m (984 ft) of ground chain per leg from the Boa Deep C construction vessel.
The Juniper project was carried out in a water depth of 100 m (328 ft).
The mooring solution engineering began in 2011 and offshore installation was completed in early November 2014. The hookup was completed in May 2015.
