Since the first containership built in 1950, containerization has growth significantly over the past 60 year. The capacity of the container vessels has been growing to support the number of containers transported. Modern containerships operate at relatively high speed and carry large amount of cargo. As a result, accident involving containerships can be catastrophic from the impact of high speed. Considering the amount of dangerous cargo and bunker in modern container vessels, the spill of dangerous cargo and fuel oil could be a severe threat to the environment. Property losses from accident scenario should not be neglected as containerships carry large amount of cargo and high cost of ships. Hence, a formal safety assessment is carry out to examine the consequences of the accidents to the environment as well as property and thus propose risk control options to reduce the risks. Event tree analysis was utilized to calculate the risk to environment and property. This is followed by reference to a feeder containership and a liner containership to compute the amount of spills and property loss onboard. Risk control options are analyzed to prevent, minimize and mitigate the consequence of the accidents. The cost effectiveness of all risk control options in controlling the accidents are compared. Finally, recommendation of risk control options that should be implemented on container vessels are made based on the proposed acceptable values in cost benefit assessment.
