Subsea Projects

We contract, manage, engineer, and execute projects using our global vessel fleet, advanced technologies, and highly skilled personnel.

Our integrated teams of project managers, engineers, and technicians collaborate to meet the requirements of your scope of work.

We deliver project-specific, integrated solutions to meet your requirements.

  • Cost efficiency
  • Risk reduction
  • Flexibility in scheduling
  • Streamlined vendor management
  • Application of advanced technologies
  • Regulatory compliance

From Engineering Design to Decommissioning

Focusing on deepwater subsea installations and field developments, we deliver tailored solutions—from the routine to the extreme. We provide fit-for-purpose engineering design through the entire asset lifecycle, including decommissioning.

Our broad capabilities include a wide portfolio of integrated subsea project solutions.

  • Project management and engineering services
  • Inspection, maintenance, repair (IMR), and refurbishment of subsea facilities
  • Deepwater subsea tie-back installation and intervention
  • Subsea inspection and integrity management
  • Design, fabrication, and installation of I- and J-tube clamp systems
  • Procurement and installation of subsea coiled tubing flowlines, flexible flowlines, umbilicals, flying leads, jumpers, pipeline end terminations (PLETs), and subsea structures
  • Flowline pigging and testing programs
  • Deepwater pipeline hot taps and pipeline remediation projects
  • Plug and abandonment (P&A) of subsea trees and infrastructure
  • Manned saturation diving services
  • Subsea development surveys, salvage operations, long baseline (LBL) arrays, ultrashort baseline (USBL) arrays
  • Strake installation to tension leg platforms (TLPs)
  • Hydrotesting and commissioning of subsea field developments
  • Steel catenary riser (SCR) tie-ins
  • Choke and pod change-outs
  • Mattress installations
Project scopes are supported by our fleet of multi-service vessels (MSVs), diving support vessels (DSVs), and research vessels.

We increase safety and efficiency during installation, operation, and recovery.

Our engineers use the latest technology and advanced processes to ensure that your high-value and project-critical flexible and rigid products can be safely installed and retrieved.

We determine the safe envelope by running simulations of minimum, maximum, and nominal offsets for current and wave conditions. We also model initiation, abandonment, and recovery with sophisticated software based on finite element analysis (FEA).
