Subsea Engineering Support

Elgenio provides engineering support for subsea construction, installation, intervention, recovery and decommissioning projects.

Our experience covers subsea structures, pipelines, flexibles, umbilicals, lifting, recovery, installation analysis, equipment design and offshore project support, with engineering developed around the practical constraints of the vessel, equipment, interfaces and offshore operation.

We can support projects from early concept and installation studies through detailed engineering, mobilisation and offshore execution.

What We Support

Our subsea engineering experience covers a broad range of offshore construction and intervention activities, including:

  • Subsea Structure Installation & Recovery
  • Pipeline, Flexible & Umbilical Installation
  • Manifold, PLEM & Tie-In System Installation
  • Subsea Equipment & Tooling Design
  • Lift Planning & Rigging Engineering
  • Dynamic Installation & Recovery Analysis
  • ROV & Diver-Assisted Operations
  • Subsea Cutting & Decommissioning Support
  • Vessel Deck Layouts & Seafastening
  • Offshore Project Engineering & Mobilisation Support

Engineering Around the Offshore Operation

Successful subsea work depends on more than the individual component being installed or recovered. Vessel capability, lifting arrangements, subsea interfaces, equipment handling, weather limits and installation sequence all influence the final solution.

Elgenio develops the engineering around the complete offshore operation, helping identify interface issues early and ensuring that analysis, equipment, rigging and procedures support a practical execution method.
