What we do
Six capabilities supporting investors, asset owners, insurers and industrial companies across due diligence, reliability, verification and failure decisions.
Industrial Risk & Condition Assessment
Condition, criticality and risk assessment for operating industrial assets.
Equipment Failure Investigation
Engineering investigation of complex failures using field evidence and analytical methods.
Claims & Loss Technical Advisory
Independent technical support for industrial losses, damage and restoration scope.
Maintenance & Reliability Review
Reliability, maintenance strategy and lifecycle improvement for critical equipment.
Technical Verification & Asset Acceptance
Independent verification of equipment, scope, technical compliance and acceptance.
Across the asset lifecycle
From acquisition and project delivery to operational reliability, major failures and recovery.

Who we work with
Independent technical advisory for industrial sectors where engineering uncertainty directly affects investment, operations and risk.
Mining & Metals
Open-pit and underground operations, mineral processing, heavy mobile equipment and fixed plant assets.
Marine & Offshore
Vessels, offshore installations, dredging and subsea equipment — including complex refits and class-driven work.
Energy & Power Generation
Conventional and renewable generation, grid infrastructure, BESS and distributed energy assets.
Heavy Transport & Logistics
Commercial fleets, freight terminals and specialised heavy-vehicle operations.
Oil & Gas · LNG
Upstream, midstream and downstream facilities, including LNG storage, bunkering and automation systems.
Insurance & Loss Adjusters
Independent engineering support for major industrial losses, claims verification and damage assessment.
Independent. Decision-focused
Three principles that define how we work and why our conclusions can be trusted.
Independent
Conclusions based on engineering evidence, not on equipment supply, repair or replacement.
Engineering-led
Field inspection, operating data, documentation and analytical methods combined where the problem requires it.
Decision-focused
The objective is a clear technical basis for investment, operational, contractual or loss-related decisions.
