Accredited operators for safety-critical marine work
Here is how MMS Marine Services Ltd keeps every operation compliant, insured, and audited — on the tidal Thames and around the South East coast.
MMS Marine Services Ltd delivers towage, safety boat standby, workboat charter, marine engineering, and coded welding across the River Thames and South East coast. Because this work is safety-critical and tightly regulated, every job is planned and executed within a documented compliance framework — from passage planning and risk assessment through to crew certification and insurance.

Qualified Crew (BML & MCA)

A documented SMS underpins every operation, supported by job-specific Risk Assessments and Method Statements (RAMS).

£10M public liability, plus employers and towage liability cover appropriate to commercial marine operations.
Quality Standards
Operations are run to recognised quality and safety management principles aligned with ISO 9001.
Risk assessment & method statements
Every operation is preceded by a job-specific RAMS tailored to the reach, harbour, or structure involved — accounting for:
- Tidal windows
- Air draught and bridge clearances
- Traffic
- The task itself
Movements on the tidal Thames are coordinated directly with Port of London Authority Vessel Traffic Services (VTS).
