Generally, Preventative Maintenance is the care or upkeep, regularly executed to an equipment to minimize the possibilities malfunctioning or failing. 


Preventative maintenance or called preventive maintenance is conventionally applied to a lot of areas where machines and equipment are present. In ships, this activity is done after a well-planned decision and schedule. Basically, this is agreed by the officials and crew members assigned specifically to this field.

Whether small or large pieces of equipment, efficient checking and maintenance are implemented even while the machinery is still functioning. By doing so, on a practically regular basis, this can essentially help the ship equipment to have a prolonged life and smooth running condition.

In every vessel, preventative maintenance can vitally help keep the machinery to be up-to-date and gain a favorable outcome. Usually, a number of machines are situated in the ship’s engine room. In this case, the engineers and particular crews responsibly carry out maintenance to promote safe and more effective operation.

Furthermore, each device, machine, or engine in ships requires preventative maintenance that should be accomplished at routine intervals of time.



Undoubtedly, sea-based machinery and equipment are more repeatedly susceptible to unfavorable conditions. Due to defects, failures, or technical faults, preventative maintenance is very much demanded.

As a matter of fact, there are different kinds of maintenance schemes or programs besides the preventive maintenance. Those that are carried out in ships but actually depends on the ship’s condition based monitoring.


  • Planned or Periodic Maintenance System – this is a time-based monitoring program that’s commonly practiced aboard the ship. It basically involves overhauling, inspection at fixed intervals, and replacement of components of a particular equipment. Periodic or planned maintenance system is observed to be expensive and definitely, involves man power.


  • Breakdown Maintenance – when a shipboard equipment fails or when a machinery breaks down, the fixes that follow is called the breakdown maintenance. Generally, this maintenance program is prevented when at sea. This is because of the limited accessibility of resources unless the machinery is crucial and being utilized.


  • Preventative Maintenance – involved in this maintenance system is cleaning, regular checking or inspections, reassembly, and lubrication. All these are performed by following the schedule of maintenance of each equipment. As well, the conditional analysis that aids in keeping the machinery’s healthy working status so as to avoid any future damage to the equipment.


The advantages of Preventative Maintenance system

  • Extends or prolongs the usefulness of machines and equipment, thus, lessens the need for major replacements.
  • Improves the performance or productivity of equipment to keep them operating more effectively and reducing power cost.
  • Develops the competency of machines by boosting uptime.
  • Enhances both internal and external customer service. Basically, because maintenance crews or staff have fewer unplanned maintenance and can reply fast to new issues or problems.
  • Delivers positively to the trustworthiness of associations or companies.


The primary key of applying preventative maintenance is to use an appropriate software aside from the fact that spending sufficient time to train ship crews and staff. The software like the Netwave Seawise “big data” technology is very significant because it can help the ship to have a more realistic and more feasible plan of action.
