TM Master
All-in-one ship management built for efficiency
TM Master brings planned maintenance, procurement, crewing, and Quality, Health, Safety, and Environment (QHSE) together in one connected system – helping you cut costs, minimise downtime, simplify compliance, and stay inspection-ready.

Every detail counts at sea
Running a safe, compliant, and profitable fleet depends on every moving part working in sync.
Every vessel is unique, with its own maintenance schedules, spare parts requirements, crew assignments, and documents to manage. Yet many operations are still managed through spreadsheets, paper forms, and disconnected systems – creating blind spots
From maintenance and procurement to crewing and compliance, every disconnect adds risk: breakdowns, delays, higher expenses, and pressure during audits. The impact can range from financial losses to endangering people, cargo, and the environment.

One connected workflow
TM Master by OneOcean brings maintenance, procurement, crewing, and QHSE into a single system, giving ship and shore teams one source of truth. Every vessel’s unique maintenance schedule, inventory, and crew assignments can be planned and tracked in one place, reducing downtime and costs.

Always inspection-ready
TM Master keeps records accurate, accessible, and audit-ready. Maintenance tasks, procurement activity, crew data, and safety and environmental processes are securely captured and easy to evidence. With everything up to date and in one place, inspections run smoothly, teams have confidence, and disruptions to operations are minimised.
