What we do
Our Service Areas
Specialist engineering disciplines, delivered by a team with deep offshore and subsea expertise.
Asset Integrity Management
Risk-based inspection programs, structural integrity assessments, life extension studies, and condition-based maintenance for aging offshore assets.
Learn moreComputational Fluid Dynamics (CFD)
Numerical simulation of fluid flow around marine structures for drag, vortex-induced motions, green water, sloshing, and ventilation studies.
Learn moreHydrodynamics
Hydrodynamic analysis of marine and offshore structures, including motion response, wave loading, fatigue, and ultimate limit state checks.
Learn moreMooring
Mooring system design, station-keeping analysis, and optimisation for floating offshore assets in demanding metocean conditions.
Learn moreProject Management Consulting (PMC)
Technical project management for marine and offshore engineering projects, including planning, coordination, risk management, and client-side support.
Learn moreRiser and Cables
Engineering and analysis of risers, umbilicals, and subsea cable systems, including fatigue, interference, and global performance studies.
Learn moreStructural Engineering
Structural design and analysis of marine and offshore structures, including fatigue, ultimate strength, and code-based verification.
Learn moreSurveys and Inspection
Planning and execution support for structural surveys and inspections, with reporting, anomaly assessment, and compliance follow-up.
Learn moreLifetime Extension
Engineering assessments and documentation to safely extend the operational life of offshore and marine assets beyond their original design life.
Learn moreWhere we work
