Seabed Trenching, Burial, and Route Preparation

We provide unmatched experience and innovative technologies to deliver solutions for the global offshore fixed and floating wind, tidal, wave, and interconnector projects.

From site investigations to cable lay and foundation installation support, we provide full life of field solutions that safely de-risk operations, increase reliability, and enable a lower total cost of ownership.

FAT, SIT, and Offshore Execution

Our highly experienced teams work to ensure the suitability of your infrastructure by completing factory acceptance testing (FAT) and systems integration testing (SIT). We execute project-specific testing and generate required reports, and are well equipped to complete immediate intervention and troubleshooting in the unlikely event that testing reveals a nonconformity.

Tie-In, Hook-Up, and Commissioning (HUC)

We help you achieve first production on time and within budget, regardless of installation type. Our extensive experience positions us well to meet your requirements for solutions and support ranging from deepwater gas fields and floating production, storage, and offloading (FPSO) units to onshore facilities.

Deepwater Operations

We deliver leading solutions for deepwater operations—from routine to extreme. We meet your requirements for global support in commissioning and operating subsea systems in the harshest and most challenging of environments.

Interventions, Workovers, and Decommissioning

We meet your needs for global subsea intervention, work over, and decommissioning using ROV- and diver-based methods. Using our experience and expertise in subsea engineering and project management, we develop subsea intervention and abandonment procedures and complete rig capability assessments.

Our innovative and practical designs provide tailored solutions to improve efficiency of well interventions and activities.

  • Light workovers
  • Subsea control module and pod replacement
  • Buoy and mooring system repairs
  • Well abandonment
  • Final field abandonment

Inspection, Maintenance, and Repair (IMR)

We ensure you are able to maintain uptime and mitigate the effects of unplanned repairs with our comprehensive inspection, maintenance, and repair programs. We develop fully-integrated subsea project solutions using the latest standards and risk-based methodologies. Our services cover the full life cycle model of production monitoring, inspection execution, engineering criticality assessment (ECA), maintenance planning, and scheduling.

We provide turnkey solutions tailored to meet the requirements of your scope of work.

  • Vessel and equipment charter
  • Offshore integration of inspection, digital video, ROV, survey, and NDT
  • Engineering, procedures, and design
  • Production of inspection data sets
  • Generation of final reports

Asset Refurbishment

We use our experience working with assets to offer services to complete the refurbishment, modification, and testing of subsea equipment including risers, subsea trees, and subsea manifolds.
