GE Oil & Gas subsidiary, PT. VetcoGray Indonesia, has been awarded a field decommissioning contract with Premier Oil Indonesia, to support the shut-down of four subsea wells in the Anoa field, offshore Indonesia.
The deal will see GE Oil & Gas prepare the field’s subsea production trees for removal, supporting the removal of flowlines and production umbilicals, installation of intervention hot stab assemblies and provision of annulus and flowline flanges. Once the wells have been made ready for decommissioning, the tree caps, subsea trees (XTs) and tubing hangers will be removed, cement plugs set and the seabed cleared to comply with local regulations. The trees were among the first to be installed by GE in the Asia Pacific region in the 1990s.
Prior to commencing the first phase of work, GE Oil & Gas will conduct interface testing with customer-supplied tooling and newly-manufactured tools, ensuring the trees are ROV-enabled for the wider decommissioning campaign, anticipated to begin in Q2 2017.
