House of Risk to Mitigate Operational Risk Strategy in Shipyards: A Case Study)

This study uses the House of Risk (HoR) method in determining the dominant risk agent and operational risk mitigation measures at the Wahana Karya shipyard.Wahana Karya is a wooden shipbuilding business whose processing system is still relatively traditional due to its simple production tools and technology.This condition has an impact on the high level of risk faced during the shipbuilding production process which results in low ship quality.Wahana Karya has not considered the level of risk in the shipbuilding process starting from raw materials, manufacturing processes, to finished products, of course this will have a detrimental impact on the industry.The House of Risk method can be used to reduce operational risk because it has been widely used in various fields, including mitigating operational risk.The House of Risk uses two phases in its work process, which can be broadly called the identification phase and the mitigation phase.The results of the House of Risk mapping at the Wahana Karya shipyard, in the first phase obtained five dominant risk agents which will be taken into consideration in the preparation of mitigation actions.While the results of the second phase of House of Risk mapping obtained six risk mitigation action plans, namely routine briefings to operators, supervision and inspection of each process, direct supervision and inspection of each process, training for operators, supervision and inspection of machine components on a regular basis, and establishing relationships with other experienced shipbuilders
