KUALA LUMPUR, Malaysia – Sapura Energy Australia has successfully completed plug removal activity for Shell’s Prelude light well intervention (LWI) campaign in the offshore Browse basin, north of Broome, Western Australia.

The campaign, awarded in June 2016, was part of thePrelude floating liquefied natural gas (FLNG) project.

The intervention vesselSapura Constructor retrieved eight suspension plugs from seven wells on the Prelude field, using a riser-less LWI system and a recently upgraded subsea intervention device and intervention compensation system, was deployed for the project.

Sapura Energy executed the work in collaboration with another of the company’s Australian subsidiaries,Total Marine Technology, which was responsible for managing the equipment used and upgrading it to comply with Shell’s specifications.

Under the same five-year call-off agreement, Sapura Energy Australia is currently working another Shell LWI campaign that involves severance and retrieval of seven wellheads. This involves use of the AXE severance system, a high-pressure water jet cutting tool designed for environmentally friendly removal of subsea wellheads that dispenses with explosives or rig-based mechanical cutting tools. Work is expected to be completed in July.

Earlier this month, Sapura Offshore won a subcontract from PT. Gunanusa Utama Fabricators on behalf of PTTEP International for theZawtika field development in the Gulf of Moattama, 290 km (180 mi) west of Tavoy on the Myanmar coast, in water depths of 120-160 m (394-525 ft).

The work scope covers EPCI of pipelines, transportation, and installation of new offshore wellhead platforms, brownfield modifications to existing platforms, and installation of a telecommunication and control system integrated to existing facilities.

Subcontract works should be completed next March.
