BACKGROUND Since it was formed in 1989, the MAIB (Marine Accident Investigation Branch) has received a number of reports about seafarers being injured, and sometimes killed, in accidents involving lifeboats. Supervisor of the data held by the MAIB (Marine Accident Investigation Branch) suggests that anyone using a lifeboat, be it in a drill or a genuine evacuation, runs a risk of being injured or even killed. Launching and retrieving a lifeboat are high-risk activities, but with proper training a ship ’ s personnel can attain the required level of familiarity to identify and overcome the potential risks. The MAIB (Marine Accident Investigation Branch) database accumulated over a ten-year period indicates that lifeboats and their launching systems have cost the lives of 12 professional seafarers, or 16% of the total lives lost on merchant ships. Eighty seven people have been injured. These accidents all occurred during training exercises or testing, with experienced and qualified seafarers either performing, or supervising, 3 the operations.
OBECTIVE The objectives of this Thesis are: Knowing the risks and failures that can be generated on a Free fall lifeboat. Knowing the level of danger that can be generated from each step of launching and recovery operation. To obtain a way to eliminate the risk and failure. 4

CONCLUSION Depend on the result of risk assessment for free fall lifeboat launching concluded that : There is so many risk can happen on the process of launching and retrieval. But that can be reduced with mitigation for decrease the frequency or give a prevention. Human error proved to be a significant contributory factor in many of the reported lifeboat incidents, as it is in most accidents. Lack of supervision was not found to be a significant factor in the cause of reported human error related incidents therefore the potential for mistakes might reasonably be expected to increase during the stress of a real emergency situation. The design and construction of lifeboats and in particular auxiliary equipment, such as brakes and release gear, play a significant part in contributing towards the cause of many lifeboat incidents with the most catastrophic event being the opening of a boat hook with the boat some distance from the water, Incidents of this nature can be avoided if the boat crew is able to confirm the hook is secure for lowering or lifting. Their repeated failure has, however, played a large role in reducing ship staff confidence in lifeboats. 17
