BAKU, Azerbaijan– The Shah Deniz consortium says the quarters and utilities (QU) platform jacket has departed the Heydar Aliyev Baku Deepwater Jackets Factory (BDJF) and is heading for installation in the Azeri sector of the Caspian Sea.
The transportation, launch, positioning, pile installation, and final completion activities of the jacket structure are expected to take around 75 days, depending on the prevailing weather conditions.
The construction of the jacket was completed ahead of schedule on Feb. 20, 2017, and was then successfully loaded onto the transportation bargeSTB-1 at the quayside of BDJF. The second jacket for the Shah Deniz Stage 2 platforms sailed away on March 15.
The QU platform jacket, built by theBOS Shelf, Star Gulf and Saipem consortium, was fully constructed in country at the BDJF, using local construction infrastructure and facilities. About 2,000 people including sub-contractors and specialist vendors were involved in the construction works. Some 90% of the construction workforce was Azerbaijani citizens.
The QU platform jacket weighs approximately 12,084 metric tons and stands 105 m (344 ft) high. It contains 31 J Tubes, seven utility caissons, and three J tube caissons. The jacket will be installed in a water depth of 95 m (312 ft).
Ewan Drummond, vice president, Shah Deniz 2 Projects, said the project is about 90% complete.
