Sapura Energy said in a press release that the campaign was part of the Shell Prelude Floating LNG Project and was the first job for Shell in Australia under its five-year call-off service agreement for LWI equipment and services provision awarded in June 2016.
The work involved the retrieval of eight suspension plugs from seven wells in the Prelude field and was performed by the Sapura Constructor, its intervention vessel whose state-of-the-art Riserless Light Well Intervention system (RLWI) including the recently upgraded Subsea Intervention Device and Intervention Compensation System, was deployed for the project.
The company noted that its Australian unit is also currently working on Shell Australia’s Light Well Intervention Campaign – Wellhead Retrieval Activity which involves the severance and retrieval of seven wellheads. The decommissioning work is being executed with the AXE severance system, a high-pressure water jet cutting system designed for the environmentally friendly removal of subsea wellheads that removes the need for explosives or rig-based mechanical cutting tools. The project is scheduled for completion in July.
