Preventive and Corrective Maintenance for Ships

0 Introduction Ship maintenance is divided into two categories: preventive maintenance and corrective maintenance. Preventive maintenance refers to maintenance performed before failure of a device or machine, the task being to maintain the level of a specific service of the device, corrective maintenance is an action taken after a failure occurs Yes, the task is to fix the defects found. Regular maintenance of cargo handling equipment used on various equipment ships is essential to ensure that the equipment is always functioning in its operating condition for rapid loading and unloading of cargo.

British standard (3811) divides maintenance into two planned maintenance and unplanned maintenance. Planned maintenance includes planned preventive maintenance and planned corrective maintenance including different definitions. Planned preventive maintenance is the work that is done to ensure that the project or facility does not exceed the expected lifespan of the facility and planned corrective maintenance is to restore projects or facilities that will not return to operation It is the work to be done.

Software maintenance can be defined as four separate activities. These activities include corrective maintenance, adaptive maintenance, comprehensive maintenance and preventive maintenance. Fixed maintenance can be explained as including the process of diagnosing and correcting errors. Adaptive maintenance, whether hardware or software, is an activity that changes software to properly connect to changing circumstances. Complete maintenance is responsible for adding new features, changing existing features, and performing periodic enhancements. This accounts for the majority of all the efforts for software maintenance. Preventive maintenance changes software, improves future maintainability and reliability, and provides a better foundation for future enhancements. This activity is rarely used. A new version will normally be released before preventive maintenance is done. All of these activities must be included in the maintenance plan.

There are two types of PC preventive maintenance: plan maintenance and state-based maintenance. Planned maintenance is periodic maintenance to prevent aged deterioration and machine damage. State-based maintenance is maintained as necessary. This is the case if one or more indicators indicate that the performance of the device is degrading. Periodic maintenance (such as data cleanup, data backup, removal of old programs, Microsoft updates, security updates, and optimization) is a necessary precaution when performing preventive maintenance.

Preventive maintenance is routine maintenance work designed to prevent computer failures and failures (Weibull, 2007). The main purpose of preventive maintenance is to prevent equipment from malfunctioning before actually occurring. These include tests, measurements, adjustments, and parts replacement, especially to prevent failures. There are two types of PC preventive maintenance: plan maintenance and state-based maintenance.
