•   Sistem Bilga pada Kapal muatan kering (Clean Bilge System)

Merupakan sistem yang digunakan untuk mengatasi terjadinya kebocora

kapal, khusus pada ruang muat dan void tank untuk kapal cargo.

•

  Sistem Bilga pada Kamar Mesin (Oily Water System)merupakan sistem yang digunakan untuk mengatasi kebocoran di kamar

mesin. Sistem ini terpisah dari sistem yang digunakan pada ruang muat

karena jenis fluida yang ditangani berbeda, yaitu air yang bercampur

minyak. Diatur dalam MARPOL Annex 2 page 18

“Bilge   lines and bilge suction are to be so arranged that the bilges can be co

 pumped even under unfavorable trim condition.”  

“Bilge  suction are normally to be located on both side of the ship. For compa

located fore and aft in the ship, one bilge suction may be considered sufficient p

that it is capable of completely draining the relevant compartment .”

CARA KERJA OWS PADA OILY BILGE SYSTSistem kerja dari bilga di kamar mesin ialah sebagai berikut :1. Oily-waste yang terkumpul di bilge well di alirkan terlebih dulu menuju oily-waste co

2. Setelah terkumpul di oily-waste collecting tank, oily-waste  kemudian di proses denganmenggunakan Oily water separator (OWS). Dimana sistem kerja dari OWS memisahkan aoli yang terkumpul di oily waste collecting tank hingga oily-waste sudah masuk dalam kategodibuang menuju overboard .3. Alat untuk mengukur kandungan oily-waste agar dapat dibuang menuju overboard dincontent monitor (OCM). Sistem kerja dari OCM cukup sederhana, apabila kandungan dariwaste  kurang dari batasan OCM, maka oily-waste langsung dibuang menuju overboard . Sedapabila, oily-waste memiliki kandungan melampaui batas dari OCM maka oily waste dialirkmenuju waste-oil collecting tank.4. Aliran dari OCM menuju Waste-Oil Collecting Tank, dialirkan secara terpisah. Untukke tempat penyimpanan yaitu waste oil collecting tank. Sedangkan air akan menuju ke oily-w

tank. Kedua collecting tank (oily-waste & waste-oil) harus disediakan sistem perpipaan menujusho

connection baik itu di portside / starboard
