20 Essential Items Every Planned Maintenance System (PMS) Should Include

The world of maritime operations is highly dependent on well-planned and efficiently executed maintenance systems. A ship’s machinery, systems, and structure face constant wear and tear due to harsh environmental conditions and continuous operation. To mitigate the risk of equipment failure, prevent costly breakdowns, and ensure crew safety, a well-structured Planned Maintenance System (PMS) is absolutely essential.

A robust PMS not only keeps critical tasks on schedule but also ensures compliance with regulatory standards and the smooth day-to-day functioning of a vessel. This blog explores 20 key elements that should form the backbone of your PMS.

What is a Planned Maintenance System (PMS)?

A Planned Maintenance System (PMS) is software that provides a structured approach to managing maintenance activities onboard a ship. It tracks what needs to be done, when it needs to be done, and allows items to be rescheduled if necessary. First introduced decades ago, PMS has become a standard tool across the shipping industry, revolutionizing how preventive maintenance is carried out.

The primary goal of PMS is to ensure equipment reliability, minimize unexpected downtime, and help the crew operate the vessel smoothly. By including key tasks in your PMS, you’re effectively reducing risks, enhancing efficiency, and ensuring compliance with industry standards.

Why Is PMS Crucial for Ships?

  • Prevents Equipment and System Failures: A reliable PMS ensures timely maintenance, helping prevent critical failures that could disrupt operations.
  • Ensures Regulatory Compliance: PMS helps maintain documentation and audit preparedness, ensuring compliance with maritime regulations.
  • Improves Operational Efficiency: With properly maintained systems, the crew can focus more on effective operations rather than reacting to emergencies.
  • Enhances Safety: A well-maintained ship is a safer ship—for both the crew and the environment.

20 Things to Include in Your Planned Maintenance System

Here’s a detailed breakdown of 20 critical elements every PMS should include. These help ensure smooth operations, extend machinery life, and provide peace of mind.

1. Flow Meter Filters

Regular cleaning of generator and main engine flow meter filters is essential to avoid malfunctions. Some blackouts have occurred because of clogged flow meter filters, which could be mitigated with scheduled cleaning.

2. Steam Return Line Filters

Often overlooked, steam return line filters play an essential role. Regular maintenance ensures efficiency and avoids system breakdowns.

3. Viscotherm Maintenance

Viscotherm ensures efficient combustion in marine engines. Include regular cleaning and checks in the PMS to maintain optimal performance and reduce exhaust emissions.

4. Funnel and Drain Inspections

Reduced crew sizes often lead to neglecting funnel maintenance. Regular inspections of structural strength, cracks, and drain clearance should be scheduled.

5. Emergency Equipment and Spare Parts

From lifeboat engines to emergency fire pumps, all emergency equipment should be maintained, with spares stocked as part of the PMS.

6. Calibration of Tools and Equipment

Ensure calibration and functionality of torque spanners, hydraulic tools, and electrical devices. Maintain logs of calibration certificates, which will also aid in audits.

7. Bow Thrusters

Bow thrusters, including bilge alarms, are crucial for maneuverability and must form part of the PMS to prevent costly breakdowns.

8. Deck Air Lines and Fog Horns

These systems are often ignored until a breakdown occurs. Maintenance schedules should include forward whistle air filters and fog horn solenoid checks.

9. Stern Light Maintenance

Despite being a vital safety feature, stern lights are often neglected. Include regular inspections in the PMS.

10. Ship’s Telephone System Maintenance

Ensure the ship’s communication systems, such as the telephone network, remain functional by scheduling regular maintenance tasks.

11. Bridge Equipment

Maintenance of bridge equipment, including radar, scanners, and batteries, ensures navigation safety and operational efficiency.

12. Evac Sanitary Systems

Particularly on car carriers, this system is often overlooked. Evac systems require routine checks and maintenance due to frequent usage.

13. Mist Box

Mist boxes on funnels should be checked periodically to avoid operational inefficiencies caused by clogging or damage.

14. Valve and Filter Box Bodies

Hidden under lagging, these components tend to be neglected until failures occur. Regular inspections can prevent catastrophic breakdowns.

15. Exhaust Fans in the Steering Room

Often neglected, exhaust fans are vital to maintaining safe temperatures. Include them in the PMS to ensure proper ventilation.

16. HotWell Maintenance

Regularly inspect the hotwell structure, filters, and stub connections. Collect and clean oil leaks using reusable sponges to maintain cleanliness.

17. Domestic Fridge Filters

The liquid suction line and return line manifold filters of fridges are often forgotten. Regular cleaning can prevent costly refrigeration issues.

18. Hot Water Circulating Pumps

Neglected due to being out of sight, these pumps require regular inspections to avoid long-term inefficiency.

19. Main Engine Air Coolers

Moisture in the air coolers can reduce efficiency. PMS should include drainage system checks to ensure performance.

20. Spare Parts Management

Regular audits of spare solenoids, relays, and other critical components can prevent delays during emergencies.

Common Pitfalls in PMS Management

Even with a robust PMS, issues can still arise if tasks are not tracked or completed properly. Here are some common mistakes to avoid:

  • Dishonest Reporting: Be transparent about incomplete tasks so that relieving crew can address them diligently.
  • Inefficient Use of PMS Software: Allocate time wisely when using software, focusing on actionable tasks rather than administrative overhead.

Enhance Your Fleet’s Efficiency with a Stronger PMS

A comprehensive PMS bridges the gap between preventative maintenance and operational excellence. By integrating these 20 elements into your system, you can ensure smooth sailing through enhanced machinery performance, crew safety, and regulatory compliance.

Remember, your PMS is only as effective as the effort put into its management. Keep it updated, transparent, and inclusive of all critical tasks.
