Abstract

Selama pengoperasian kapal, kecelakaan dapat terjadi karena kurangnya perawatan pada peralatan, Perawatan pada sistem perpipaan sangat penting untuk personel keselamatan dan lingkungan. Salah satu sistem di kapal sebagai sistem darurat adalah sistem bilga. Sistem bilga terdiri dari dua yaitu sistem lambung kapal dan sistem lambung kapal berminyak. Sistem lambung kapal berminyak untuk mengambil minyak dari campuran air. Penahanan minyak dalam campuran air minimal di bawah 15 ppm untuk mencegah kerusakan lingkungan. Strategi pemeliharaan diperlukan untuk menghindari risiko kegagalan. Untuk mengidentifikasi mode kegagalan, terdapat Failure Mode and Effect Analysis (FMEA) dan Hazard of Operation Study (HAZOP) yang dirancang untuk mengidentifikasi potensi mode kegagalan peralatan. Setiap penilaian risiko memiliki kelebihan dan kekurangan yang berbeda. Berdasarkan hasil skripsi ini, terdapat 24 tugas perencanaan pemeliharaan dan penjadwalan sistem bilga. Persentase strategi perawatan untuk setiap jenis mode kegagalan adalah Preventive Maintenance (PM) sebesar 38%, Corrective Maintenance (CM) 33%, dan Failure Finding (FF) 29%. Selain melakukan strategi perawatan, perhitungan tingkat kehandalan dan kegagalan peralatan menggunakan software ReliaSoft Weibull juga penting. Hal tersebut menunjukkan bahwa keandalan peralatan dapat menurun, dan tingkat kegagalan peralatan dapat meningkat seiring berjalannya waktu. ==================================================================================================================== During ship operation, an accident may occur because of a lack of maintenance on the equipment. Maintenance on the piping system is essential for safety personnel and the environment. One of the system on the ship as an emergency system is bilge water. Bilge water system consists of two, bilge system and oily bilge system. Oily bilge water system is for taking the oil from water mixture. The oil containment in water mixture minimal 15 ppm to prevent harm to the environment. Maintenance strategies are needed to avoid the risk of failure. To identify failure mode, there are Failure Mode and Effect Analysis (FMEA) and Hazard of Operation Study (HAZOP) that designed to identify potential failure modes of equipment. Every risk assessment has different advantages and disadvantages. Based on this thesis's result, there are 24 planning maintenance tasks and a schedule for the bilge water system. The percentage of maintenance strategies for each type of failure mode is Preventive Maintenance (PM) is 38%, Corrective Maintenance (CM) 33%, and Failure Finding (FF) 29%. Besides doing maintenance strategies, calculation of the reliability and failure rate of equipment using ReliaSoft Weibull software also important. It showed that equipment reliability could decrease, and the failure rate of equipment can increase as time went by
