The sea is a part which can not be separated from the life of human beings and other living beings, for it to be a great concern for the whole of the institution in the world to make a regulation related to all activities that interact directly with the sea.
How To Prevent Oil Spills
With the increasing demand for oil as the energy source to prevent the occurrence of oil spills at sea by the tanker then issued legislation or international regulations approved by the IMO. MARPOL 73/78 is the International Convention for the Prevention of Pollution from Ships, 1973 as modified by the Protocol of 1978. (“MARPOL” is short for marine pollution and 73/78 short for the years 1973 and 1978.)MARPOL protocol with 73/78 where not allowed to dispose of oil into the sea so that its implementation arises the provision of prevention, among others:
Procurement of ballast tank Separated or COW (Crude Oil Washing) on a particular tank ship size coupled with ODM (Oil Discharge Monitoring and control system), oil Separator equipment, and so on.
- Limit the amount of oil that can be dumped into the ocean.
- The area of the disposal of oil.
- Necessity of special oil ports to provide shelter slop tank.
To prevent pollution by oil that comes from the ship mainly tankers in Annex I contained the regulations of prevention with emphasis as follows:
Regulation 13, Segregated Ballast Tanks, the Dedicated Clean Ballast Tanks and Crude Oil Washing (SRT, CBT and COW).
According to the results of the evaluation of the IMO, the best way to reduce the Oil Spills because the operations are complete the tanker with one the following precautions systems:
Segregated Ballast Tanks (SBT)
Special water ballast tanks are completely separated from the cargo of oil tanks or oil fuel tank. The system must also have separate pipes, water pipes shall not pass through ballast tanks of the oil charge.
The Dedicated Clean Ballast Tanks (CBT)
The former tank charge is cleared to filled with ballast water. Ballast water from the tank, if disposed of into the sea would not seem the former oil over the surface of the water and when discarded via the controller tool oil (Oil Discharge Monitoring), oil in water should not be more than 13 ppm.
Crude Oil Washing (COW).
The charge of crude oil that was circulated as media of auxiliary tanks that are being disassembled charge to reduce the deposition of oil remaining in the tank.
