TMC Marine

What TMC Marine does

TMC (Marine Consultants) Ltd, trading as TMC Marine, is a London-headquartered international marine consulting firm established in 1979 and operating as a wholly-owned subsidiary of Bureau Veritas Marine & Offshore SAS. The firm delivers specialist marine surveying and consultancy services — casualty response, salvage and wreck removal, marine claims investigation, expert witness work, inspections and audits, design and engineering consultancy, and marine warranty surveys — to P&I clubs, insurers, shipowners, charterers, cargo interests and oil & gas / renewable energy operators. TMC holds three Special Casualty Representative appointments on the Lloyd's of London Panel and is an Associate Member of the International Salvage Union, providing it with eligibility for high-value emergency-response mandates worldwide.

The firm's intellectual property centres on in-house engineering software led by SEAMASTER, a longitudinal-strength, intact-stability and cargo-loading program that has been installed on 250+ vessels trading worldwide and is approved by LR, DNV, BV, ABS, NKK and GL. SEAMASTER is extended by SEADAM (post-casualty residual strength assessment), COMLASH (container stack lashing analysis) and SEAMAN (maneuvering and collision-reconstruction analysis). These tools, combined with a 300+ similar-ship model database and over 11,000 cases completed since 1979, underpin TMC's consulting output across engineering, legal and insurance mandates.

TMC operates through offices in London, Southampton, Medway, Newcastle, Stamford, Singapore, Shanghai and Melbourne, with 24/7 emergency response coordination from London and Singapore. The firm serves enterprise clients through direct engagement and Bureau Veritas group channels rather than through traditional marketing, with revenue generated on a project-based consultancy and software licensing basis. No public pricing, ARR or revenue figures are disclosed in available materials.
