Designing a Maintenance System Plan to Increase Effectiveness and Efficiency on The MT Success Altair XLII Ship

The MT Success Altair XLII, an oil tanker with a tonnage of 45,000 DWT, requires regular routinemaintenance to maintain its performance and crew safety. An integrated and structured maintenanceplanning system can increase maintenance effectiveness and efficiency and reduce the risk of accidents.However, implementing the Plan Maintenance System (PMS) on board the ship was not optimal, re-sulting in a fatal accident in 2019. Therefore, the research ”Designing a Plan Maintenance System toIncrease Effectiveness and Efficiency on the MT Success Altair XLII Ship” is proposed to improve shipmaintenance performance. The conclusions of this research emphasize the need for routine mainte-nance of ship safety equipment, structured maintenance planning, and crew discipline in implementingPMS. The suggestion is that disciplined human resources should implement PMS and familiarize thecompany with the help of shipping consultants. Hopefully, this research can help ship managementcompanies improve ship maintenance performance and operational safety in the future.
