Offshore CMMS software is a Computerized Maintenance Management System configured for the technical requirements and operational environment of offshore support vessels — including platform supply vessels (PSVs), anchor handling tug supply vessels (AHTS), construction support vessels, pipe-laying barges, well intervention vessels and emergency response vessels. It manages planned maintenance schedules, corrective work orders, running hours tracking, spare parts inventory, class survey compliance and DP system maintenance in a single integrated system that functions reliably in the low-bandwidth, high-latency connectivity environments typical of offshore operations.
Offshore CMMS software must address a maintenance management challenge that is significantly more demanding than for merchant shipping. Offshore support vessels operate complex, high-value equipment — thrusters, DP control systems, deck handling equipment, subsea deployment systems, firefighting systems, well control equipment — under sustained high utilisation in harsh marine environments. Equipment failures offshore carry higher consequence than equivalent failures in port: emergency repair logistics are expensive, client contractual obligations may be triggered, and operational safety risks are elevated in the offshore environment. A well-implemented CMMS that enforces preventive maintenance discipline is the most effective tool available to the Technical Superintendent for managing this risk.
Dynamic positioning is the central technical capability of most modern offshore support vessels, and DP system maintenance is the highest-priority maintenance programme on a DP-classed vessel. The DP maintenance programme covers azimuth thrusters and tunnel thrusters, the DP control computers and software, position reference systems (DGPS, acoustic positioning, taut wire), gyrocompasses, wind sensors and the vessel’s power management system. Classification society rules require that DP-related maintenance be completed on schedule and documented to a standard that supports the annual DP proving trial. Offshore CMMS software that integrates the DP maintenance programme with the broader planned maintenance schedule — with the same work order structure, completion documentation and history tracking as other equipment maintenance — ensures that DP maintenance receives the priority and documentation quality it requires.
Construction support vessels and pipe-laying vessels carry specialised deck and subsea equipment — cranes, winches, A-frames, moonpools, ROV hangar and deployment systems, tensioners and carousel systems — with complex maintenance requirements tied to both manufacturer schedules and classification society rules for lifting appliances and offshore equipment. Offshore CMMS software must accommodate the equipment hierarchy of these specialist vessels without requiring the Chief Engineer to manage a separate maintenance system for deck and subsea equipment outside the main CMMS.
Offshore support vessels operating in deepwater fields, remote offshore installations or Arctic environments may have limited or intermittent satellite connectivity. An offshore CMMS must function fully in offline mode — allowing the vessel crew to create work orders, record completions, update running hours and manage spare parts without connectivity — and synchronise reliably with the shore system when connection is available. Data integrity during synchronisation is critical: maintenance records created during an offline period must upload without overwriting concurrent updates made by the shore team.
STAR Suite™ provides offshore support vessel operators with a CMMS that covers the full equipment complexity of OSVs, with DP maintenance integration, offline-capable operation, class survey tracking and spare parts management in a single platform. Chief Engineers manage the vessel’s complete maintenance programme; Technical Superintendents monitor compliance from shore.
OSV fleet management software — the fleet-level platform above the vessel CMMS, providing fleet-wide oversight.
PSV maintenance management software — maintenance management specifically for platform supply vessels.
AHTS vessel maintenance system — maintenance management for anchor handling tug supply vessels with specialised deck equipment.
