Claxton has won a contract to provide high-pressure riser and abrasive jet cutting services to the Deep Panuke decommissioning project offshore Canada.
The gas field is about 250 km southeast of Halifax, Nova Scotia, on the Scotian Shelf. Deep Panuke field ceased production in May 2018 and the operator has begun planning facility and well decommissioning activities.
For this major project, Claxton is supplying a high-pressure subsea drilling riser system with associated services in a shallow-water programme to connect the surface blowout preventer stack on the rig with subsea horizontal trees. Claxton’s SABRE subsea abrasive jet cutting system will then perform well severance 3 m below the mudline.
The work will be undertaken on five subsea wells from the harsh environment offshore, jackup drilling rig Noble Regina Allen, which has been engaged by the project operator.
The well plug-and-abandonment programme is expected to start in January 2020. The running, operation and pulling of the riser on each well will take about 25 days and will be followed by the cutting phase. The campaign is expected to finish in mid-July 2020.
