SUBSEA RISER HIGH-PRESSURE RISER SYSTEM
Maersk Drilling required support with their abandonment program in the central North Sea, for eight wells on the Leadon Field and two wells on the James Field. Following a successful tender process, Aquaterra Energy delivered a complete subsea high-pressure riser system, the associated equipment and a detailed riser analysis report to the Maersk Gallant by February 2017.
The rig was initially deployed to the James Field in March 2017 where the subsea high-pressure riser system was run, allowing for the successful re-entry into the wells for the abandonment program to begin.
Key modification work was required in order to accommodate the running of a subsea high-pressure riser system, as well as the associated abandonment equipment.
Handling and storage of the subsea high-pressure riser and its associated equipment was possible due to the development of project specific procedures
