HOUSTONDelta SubSea LLC and Optime SubSea AS have entered into an agreement to provide combined service solutions to their clients’ deepwater control needs, whether it is XT control for installation, interventions, testing, SCM diagnostics or other subsea XT test or controls applications.

This enhanced capability will be supplied via their small and light deepwater Intervention Workover Control (IWOC) system for 3,000 m (9,843 ft) waters.

Scott Dingman, CEO of Delta Subsea LLC, said: “This system provides great cost and operational benefits for our current customers, but also opens up new opportunities for reducing costs and complexity, and increasing the functionality of XT control operations. The IWOC system combines the stringent requirements from traditional subsea control systems developed to operate permanently installed subsea equipment with the modularity, flexibility, and low cost traditionally seen in the ROV industry.”

The companies say that the benefits of this light IWOC’s system are in the reduced footprint obtained by moving the hydraulics subsea. This removes the need for larger and heavier topside hydraulic umbilicals, reels or designated containers. This, in turn, reduces the cost of mobilization/demobilization; reduces operational time required; and increases safety by avoiding handling and clamping topside.

They also note that with a lighter and smaller system also comes the benefit of increasing subsea operations to a traditional support vessel.

“This IWOC system will potentially free up the drilling rig and allow installation to be carried out by one of our fleets IMR vessels,” Dingman added. “This system can be utilized for installation and testing of subsea trees as well as operating and overriding of the same subsea assets. The IWOC system is supported subsea via the Delta SubSea ROV system(s) and associated intervention tooling as required. By using this system, we estimate that customers can achieve a 60% cost savings directly on installation cost in many of their projects.”
