Marine transportation is supporter of the world trade. Even though the regulation had been implemented, marine transportation still has risks in the voyages. One of the risks is ship collisions. The purpose of this study to identify the root causes of ship collisions in Indonesian waters and identify preventive action to reduce the ship collision. The study based on forty- six collisions occur between 2010 till 2018. This study uses House of Risk Method. The House of Risk (HOR) consists of two phases. The House of Risk Phase 1 is deployed to reveal the risks agent of the accidents. and the analysis risk agents which critical category. The House of Risk Phase 2 developing measures to mitigate the risk agent critical category. Risk agent critical category is root cause of ship collisions. The root cause of ship collision in this study is crew recruitment process is not accountable, Shipping company does not implement appropriate maintenance plan, and clearance out letter approved without inspection to the ship. The preventive actions are creating a system and using technology to ensure shipping companies provide up-to-date information about the ship's condition, create a system and use technology in assessing seaworthy requirements, create a system to ensure the crew on board have appropriate competence, create a system to ensure shipping companies carry out the selection process in crew recruitment, and create a system to ensure shipping companies conduct competency tests on crew recruitment. Stage of crew preparation, and voyage preparations are the most critical stages to be aware, in order to reduce of ship collision should be to create a system in the crew recruitment procedure at the crew preparation stage and create a system in the clearance out procedure at the sailing preparation stage. The conclusion of this study is the ship collision caused by a combination of several interrelated causal factors, so that to minimize the risk of ship collision have to take a systems approach.
