Jacket cooling fresh water merupakan salah satu permesinan bantu dan
peralatan penting yang ada di atas kapal. Jacket cooling berfungsi sebagai selimut
silinder liner yang didalamnya berupa air tawar dengan temperatur tertentu yang
digunakan untuk menyerap panas yang dihasilkan oleh pembakaran didalam
silinder. Sebuah penukar panas jenis multitubular digunakan untuk menghilangkan
panas dari pendingin. Jacket cooling. Salah satu bagian penting adalah oring
connecting jacket yang berfungsi sebagai perekat antara jacket cooling dengan
cylinder head agar air pendingin dapat bersirkulasi dalam melakukan pendinginan
mesin induk.
Setelah dilakukan penelitian menggunakan metode Hazop dan USG
(Urgency, Seriusness dan Growth). Penyebab kebocoran pada jacket cooling fresh
water adalah kerusakan pada komponen-komponen sistem pendingnan tertutup
adalah, pipa, air tawar, pompa, oring connecting jacket. Hasil penelitian mengacu
pada kerusakan salah satu komponen tersebut yaitu oring connecting jacket, hal ini
mengakibatkan pendingin air tawar keluar dari sistem pendinginan tertutup.
Oleh karena itu perawatan dan perbaikan yang teratur dan sistematis pada
komponen-komponen tersebut terutama oring connecting jacket sangat mutlak
diperlukan agar sistem pendinginan tertutup bekerja optimal. Semua itu akan
penulis bahas pada skripsi ini.

Jacket cooling fresh water is one of the auxiliary machinery and equipment
it is important that there is on board. Jacket cooling serves as a blanket cylinder
liner which is inside in the form of fresh water with a certain temperature which is
used to absorb the heat generated by combustion in the cylinder. A multitubular
heat exchanger type used to dissipate heat from the refrigerant. Jacket cooling One
important part is the oring connecting jacket that serves as an adhesive between the
cooling jacket with the cylinder head so that the cooling water can circulate in the
conduct of the parent engine cooling.
After the research is done using methods of Hazop and ultrasound (Urgency,
Seriusness and Growth). The cause of the leak in fresh water cooling jacket is
damage to the components of the closed cooling system, fresh water, pipes, pumps,
oring connecting jacket. The research refers to damage to one of the components
namely oring connecting jacket, this results in cooling fresh water out of the closed
cooling system.
Therefore maintenance and repair are regularly and systematically on these
components primarily oring connecting jacket very is absolutely necessary in order
for a closed cooling system works optimally. All of that will be the author discussed
in this thesis.
