Step Delivers Drilling Fluid, Well Control System to Rolls-Royce Marine

Aker Solutions' wholly owned subsidiary STEP Offshore has delivered a drilling fluid and well control system to Rolls-Royce Marine, which will be used on the Yme field in the North Sea.

The Aker Solutions unit made a fast and efficient delivery of an ultra compact skid mounted system for drilling fluid circulation and well control to the customer. Pal Eriksen, President of STEP Offshore, says: "Yet again STEP Offshore has taken on a complicated project with a tight deadline, and has delivered according to the customer's expectations. We are proud to have successfully delivered this project to Rolls Royce Marine."

The system is designed for a light work-over unit to the Talisman Energy-led Yme oil field project in the North Sea. The unit is designed for easy transportation to and from the well-head platform, with instant easy hook-up to the work-over unit for well intervention operations in already drilled and completed wells.

System delivery

The system includes trip tanks, pumps, remote controlled valves, stand pipe manifold, choke and kill manifold, HPU, instrumentations, control system.

The main functions are:

  • Continuously monitoring the drilling fluid volume in the well by the dual trip tank system while tripping in and out of the hole
  • Routing drilling fluid from seawater pumps or water injection system to standpipe (hole), trip tank system or choke & kill manifold
  • Performing choke & kill operations

The control of the trip tank system is performed from the drillers control desk, while the chokes are controlled from a stand-alone choke control panel in the driller's cabin. The choke control panel utilizes a 19" touch screen for easy and clear control of the choking process.
