The system is primarily designed for wellbore tubular extraction and conductor pre-installation but can be customised for many other well servicing, decommissioning and construction activities. The system excels where limited space and tight deadlines dictate equipment with a minimal footprint and fast assembly time.

  • Offshore & Onshore
  • Decommissioning
  • Well Abandonment
  • Wellbore Tubular Extraction
  • Conductor Pre-Installation
  • Setting New Casing
  • Downhole Operations

In July 2015 the system was deployed on a North Sea Platform where it was quickly assembled and used to pull 50ft section of conductor as an integral part of the decommissioning project.

The RIS can be adapted for a number of operational needs that replaces the traditional rig approach giving cost and time savings. To discuss your potential project or upcoming needs in more detail please call +44 1224 249355
