Support across the full life of an offshore asset

From the first concept sketch to the day a platform leaves the field, offshore assets need engineering that is careful, practical and safe. We offer five connected service lines. Use one, or bring us in across the life of a project for continuity from start to finish.

Our service lines

  • Engineering and Design

    Good offshore design balances safety, cost, constructability and decades of operation. Our engineers bring field experience to the drawing board, so the decisions made early hold up when steel meets sea.

    • Concept and feasibility studies
    • Front-end engineering design (FEED)
    • Detailed engineering across structural, mechanical, piping, process and electrical disciplines
    • Brownfield modifications and life-extension studies
    More about engineering and design
  • Subsea Services

    Subsea systems are expensive to reach and costly to fix. We help operators get them right first time and keep them running for as long as the field needs them.

    • Subsea system and field layout engineering
    • Pipeline, riser and umbilical engineering
    • Intervention planning and procedures
    • ROV and diving support engineering
    More about subsea services
  • Inspection, Maintenance and Repair

    Many of the world’s offshore platforms are operating well beyond their original design life. Keeping them safe and compliant takes a disciplined, data-driven approach to inspection and maintenance. That is what we provide.

    • Risk-based inspection planning
    • Structural and topside inspection
    • Corrosion monitoring and integrity assessment
    • Maintenance strategy and planning
    More about inspection, maintenance and repair
  • Offshore Installation Support

    Offshore installation leaves little room for error. Weather windows are short, vessels are expensive and every operation has to be engineered in detail. Our team helps operators and contractors plan and execute these campaigns with confidence.

    • Installation engineering and method statements
    • Lift, transport and sea-fastening engineering
    • Marine operations planning and weather window analysis
    • Hook-up and commissioning support
    More about offshore installation support
  • Decommissioning

    Decommissioning is the final chapter of an offshore asset, and one of the most scrutinised. Regulators, communities and shareholders expect it to be done safely, on budget and with care for the marine environment. We help operators meet that expectation.

    • Decommissioning strategy and options studies
    • Regulatory and environmental planning support
    • Well plug and abandonment engineering support
    • Removal engineering for topsides, jackets and pipelines
    More about decommissioning
