Ship maintenance is ship maintenance and repair activity carried out alone or by other parties, either during the operating period or outside the ship’s operational period, to maintain the ship’s feasibility so that it can operate optimally. Currently, ship owners are scheduling ship maintenance using a system called the Planned Maintenance System.
A planned Maintenance System is a paper or software-based system that allows ship owners or operators to carry out ship maintenance within a certain period based on the requirements of the manufacturer and ship classification agency.
The Purposes of Using the Planned Maintenance System include:
1. Ensure all ship maintenance is carried out at appropriate time intervals and according to the schedule created by the system.
2. To maintain and keep all machinery and components in good working order.
3. To avoid any disturbance when the ship is operating.
4. To minimize downtime from possible damage.
5. To provide clear boundaries between maintenance on board and land.
6. To improve the safety and reliability of the ship.
The ship’s maintenance is supervised by personnel on board, which are then recorded as inspection items for the ship’s periodic survey. Plans and schedules of ship maintenance are documented according to a system approved by the ship classification agency. A Planned Maintenance System or a Planned Maintenance System is currently mandatory following the ISM (International Safety Management) Code.
Software-based Planned Maintenance System is currently very developed, and various programs for ship maintenance appear more and more. Ship owners or operators can choose modules in the Planned Maintenance System software according to their needs. The current Planned Maintenance System program is not only about ship maintenance but also covers all needs on and off the ship.
The Planned Maintenance System program ship maintenance (maintenance) must meet the requirements of the ISM (International Safety Management) Code. The database must include all vital equipment on board, and all such equipment must have a clear maintenance plan. The ship classification agency gives special status to ships implementing the Planned Maintenance System correctly.
Surveys for onboard machinery are usually carried out concurrently with surveys carried out by classification bodies surveyors and based on the schedule given in the Continuous Machinery Survey. In addition, machining inspections are scheduled every five years to ensure the machining system is functioning correctly. The ship classification agency allows the use of the form created by the Planned Maintenance System for conducting surveys.
In general, the inspection of the Continuous Machinery Survey, except for the steering gear and pressure vessel, can be carried out by the Head of the Engine Room, based on the Planned Maintenance System work program.
The following are some of the requirements for the Head of the Engine Room in the Continuous Machinery Survey, including:
• Have a valid ATT II diploma
• Has experience as Head of Engine Room for ships with the same central engine for at least one year
There are several types of ship maintenance activities, including:
1. Planned Maintenance System
2. Maintenance to deal with Internal or External Audit
3. Maintenance to face inspection by Port State Control
4. Maintenance and repair following the Continuous Machinery Survey (CMS) determined by the ship classification board
5. Maintenance and repairs while the ship is docked
