A Planned Maintenance System (PMS) is a digital system used to plan, schedule, execute and document maintenance activities for vessels and maritime assets. It helps shipowners, ship managers and operators ensure that maintenance is carried out at the correct intervals, equipment remains in safe operating condition and maintenance records are accurately documented.
Rather than relying on manual planning or spreadsheets, a Planned Maintenance System centralises maintenance information, making it easier to manage work orders, equipment history, maintenance intervals and technical documentation throughout the lifecycle of each asset.
Within a modern maritime organisation, a Planned Maintenance System forms the foundation of technical maintenance. While Fleet Management Software provides operational oversight across the entire fleet, a PMS focuses specifically on planning, controlling and documenting maintenance activities for individual vessels and equipment.
Many organisations also integrate their PMS with Maritime EAM Software to improve asset lifecycle management and maintain complete visibility of equipment condition, maintenance history and long-term asset performance.
Modern vessels contain thousands of maintainable components, each with its own maintenance requirements, operating limits and inspection schedules. Managing these activities manually becomes increasingly difficult as fleets expand and regulatory requirements grow more demanding.
A Planned Maintenance System provides a structured framework for organising maintenance activities, ensuring that routine servicing, inspections and equipment overhauls are completed according to planned schedules rather than after failures occur.
This supports preventive maintenance strategies that reduce unplanned downtime, improve equipment reliability and extend the service life of critical assets.
By maintaining complete maintenance records and providing full traceability of completed work, a PMS also helps organisations demonstrate compliance during inspections, audits and classification surveys while supporting the objectives of Maritime Compliance Software.
A Planned Maintenance System organises maintenance activities based on predefined maintenance plans that are linked to specific equipment and assets.
Maintenance tasks may be triggered by:
When maintenance becomes due, the system generates work orders that guide onboard personnel through the required activities. Engineers can record completed work, document findings, report defects and update equipment history directly within the system.
Most maritime PMS solutions also maintain a complete maintenance history for every asset, allowing technical managers to review previous work, identify recurring failures and support long-term maintenance planning.
Because vessels often operate with limited internet connectivity, modern PMS solutions allow maintenance work to continue offline before synchronising information with shore-based teams once communication becomes available.
Although functionality varies between providers, most maritime Planned Maintenance Systems include a common set of capabilities that support technical maintenance throughout the vessel lifecycle.
The primary function of a PMS is to organise maintenance activities before equipment failures occur.
Maintenance schedules are created using predefined maintenance intervals based on time, running hours or manufacturer recommendations, helping organisations establish consistent preventive maintenance programmes across every vessel.
A Planned Maintenance System automatically generates work orders when maintenance becomes due.
Work orders define the required maintenance tasks, provide instructions for onboard personnel and create a complete record of completed work for future reference.
Every maintenance activity contributes to the equipment's maintenance history.
Maintaining complete historical records enables engineers and technical managers to identify recurring issues, evaluate equipment reliability and make better-informed maintenance decisions over time.
Many vessels classify certain systems as critical equipment because failures could affect safety or operational capability.
A Planned Maintenance System helps organisations identify critical assets, monitor maintenance status and ensure that essential equipment remains available and maintained according to company procedures and regulatory requirements.
A PMS centralises maintenance records, inspection reports, service history and supporting technical documentation.
When integrated with Ship Maintenance Software, organisations gain a connected maintenance environment where planning, execution and documentation remain linked throughout the maintenance process.
Modern Planned Maintenance Systems enable onboard crews and shore-based technical teams to work from the same maintenance information.
Maintenance updates completed onboard can be synchronised with shore offices, improving planning, technical oversight and communication while reducing duplicated work and manual reporting.
A Planned Maintenance System primarily supports preventive maintenance, where maintenance activities are performed at planned intervals before failures occur. Preventive maintenance helps reduce equipment downtime, improve reliability and extend the operational life of onboard assets.
Corrective maintenance, by contrast, is carried out after a fault or equipment failure has been identified. While corrective work cannot always be avoided, an effective Planned Maintenance System helps organisations reduce the number of unplanned repairs by ensuring that routine maintenance is completed on schedule.
By combining preventive maintenance with structured work orders, equipment history and maintenance records, organisations gain greater control over maintenance planning while reducing operational risk.
Maintenance is a fundamental part of maritime safety and regulatory compliance. International regulations, classification societies and company procedures require vessel operators to demonstrate that maintenance activities are planned, completed and documented correctly.
A Planned Maintenance System supports these requirements by maintaining complete maintenance records, inspection histories and documentation for equipment throughout its operational lifecycle.
When integrated with Maritime Compliance Software, organisations can more easily prepare for internal audits, flag state inspections, port state control and classification surveys while maintaining accurate and traceable maintenance documentation.
Maintaining structured maintenance records also supports continuous improvement by providing technical managers with reliable information for planning future maintenance activities and demonstrating compliance with internal maintenance procedures.
A well-implemented Planned Maintenance System provides significant operational, technical and regulatory benefits throughout the organisation.
Key benefits include:
By providing a structured approach to maintenance management, a Planned Maintenance System helps organisations move from reactive maintenance towards a proactive maintenance strategy that improves safety, operational efficiency and long-term asset performance.
A Planned Maintenance System is used by both onboard personnel and shore-based technical teams responsible for maintaining vessels and maritime assets.
Typical users include:
Although responsibilities vary between roles, all users benefit from access to accurate maintenance information, consistent work processes and complete equipment histories.
STAR Suite™ provides a maritime-specific Planned Maintenance System that helps organisations plan, schedule and document preventive and corrective maintenance throughout the asset lifecycle.
Maintenance plans can be configured using calendar intervals, running hours and equipment-specific requirements, ensuring that maintenance activities are performed consistently and documented accurately.
Integrated work order management, equipment history and maintenance records give onboard crews and shore-based technical teams a shared overview of maintenance status while supporting efficient planning and execution.
When combined with Maritime Compliance Software, organisations can maintain complete maintenance documentation for inspections, audits and regulatory requirements. Integration with Fleet Management Software also provides fleet-wide visibility into maintenance performance and technical activities across multiple vessels.
