The high of oil demand as a fuel causes the
demand for supply to the community is also high.
Therefore, the intensity of Indonesia's tanker shipping
vessel also increased. Ship accidents can cause oil spills.
Polluted seas and loss of lives are the result of oil spills.
To tackle shipwreck accidents that result in oil spills,
IMO issues related rules to prevent damage, including
the HNS Convention. The Convention requires
restrictions on costs incurred by the ship owner to
prevent damage to oil spills. But until now Indonesia
has not ratified the regulation.
The Formal Safety Assessment method is used to
assist the steps in risk assessment and cost benefit
analysis calculations if Indonesia considers ratifying the
HNS Convention and its amendments. This method is
used to identify potential hazards, determine the risk
profile of each accident case and calculate the costs and
benefits when ratifying the HNS Convention. The
purpose of this research is to know the potential danger
causing the oil tanker to have an oil spill accident, to
analyze the cost of clean up given the happening of oil
spill, and to recommend how far the ratification needed
to regulate the compensation cost in case of tanker
accident along with the effect obtained when
considering ratifying the relevant rules.
The result of this research is the potential of ship
accident causing oil spills such as fire, sinking, aground
and collision. The risk profiles of all types of ship
accidents are at level 9, level 10 and level 11. The cost of
clean up for oil spill accident cases is varied, with the
smallest cost of US $ 1,950 and the largest cost of US $
390,000. Based on the calculation of the cost and benefit
shows that Indonesia needs to ratify the HNS
