DOHA, Qatar -- J. Ray McDermott ME has installed the second topside for the QG3&4 project. The QW9 topside was fabricated in Jebel Ali, Dubai along with the QW7 and QW8 decks. The topsides were lifted off the cargo barge by McDermott’s DB101, installed over the pre-drilled wells, and set onto the jacket.
The deck was loaded out and seafastened onto the cargo barge in early August. The offshore lifts included removal of two temporary decks and installation of the topsides, helideck, and flare boom. The two risers for pipelines 9-7 and 9-8 were previously stalked onto the jacket.
Once complete, the QW9 will form one of a trio of platforms that will deliver gas to Qatargas Train 6 and Train 7 through two, 38-in. (97-cm) diameter pipelines.
