NOTODDEN, Norway – Aker BP has contracted Optime Subsea to provide well access system/services on the company’s fields offshore Norway.
Optime’s Subsea Controls and Intervention Light System (SCILS) was used recently for a two-well P&A campaign on the Jette field, reportedly saving on rig time, personnel, and equipment.
Aker BP has now taken the contractor’s new subsea hydraulic pump Intervention Workover & Controls (IWOC) system on a long-term lease, for use with the semisubmerible drilling rig Deepsea Nordkapp.
According to Optime, traditionally IWOC systems have comprised large 20-ft (6-m) topsides containers with equilly large umbilical and reels, carrying hydraulics and electrical power. As a result, they can weigh up to 50 tons in total.
Optime’s SCILS, however, transfers the hydraulic control to subsea, with no need for a topsides container and an attendant reduction in size of the umbilical and reel.
The SCILS’s total weight is 3-7 tons, depending on the reservoir size and configuration.
In preparation for completions on the Skogul field development, Aker BP will perform full interface testing toward the Xmas tree at Optime’s workshop in Notodden.
The goal is to simplify interface issues that would normally come to light on the rig – but in this case its is only possible because of the small size of the SCILS.
The system can mobilize or demobilize within a day, compared to five-seven days for a traditional system, Optime claimed.
