A historic milestone in Qatar: the first locally fabricated platform successfully installed by Aegir

Qatargas’ North Field Bravo Expansion

The original North Field Bravo (NFB) accommodation, installed in 1995, was designed for the operational needs of Qatargas Trains 1 and 2. The existing North Field Bravo complex contains an existing Living Quarter (LQ) facility, which is insufficient for the present workforce on the complex. The objective of the NFB expansion is to provide additional accommodation to the NFB facility to cater for changes in the operational requirement. This will be achieved by a new living quarter platform designed for 90 persons adjacent to and bridge linked to the existing quarters.

Installation by Aegir

On February 13, Aegir picked up the 2,200 metric ton jacket and piles from the Ras Laffan quayside at sunrise and then sailed to the offshore site, upended, and positioned the structure by midnight. In the subsequent days the main piles, consisting of a lead section and two add-ons, were installed and driven to target penetration. Then Aegir returned to the NKOM yard to pick up the topside, lifting the 2,800 metric ton structure from the quayside and setting it onto the vessel's deck on February 22. The following morning Aegir sailed to the offshore construction site, where the deck was successfully installed around midday on February 23.

Both mobilizations were completed within a combined 18 hours, and were executed safely with zero recordable HSE cases.
