Currently, electricity is one of the developing fields and plays an important role in the socio-economic life of Vietnam. In which, the power output provided by thermal power plants is very large. In order to ensure stable operation and high productivity of thermal power plants, the Government and people of Vietnam have been making efforts to improve the infrastructure, especially the logistics of shipping by sea to serving the operation of thermal power plants. However, shipping by sea, Vietnam still faces many challenges that need a lot of effort to solve. Currently, shipping by sea is very risky, causing negative impacts on the operation of thermal power plants. In which, the coal supply system plays an important role. Risk assessment has been recognized as a useful tool to identify hazards, analyse weaknesses and risks of shipping by sea, and select appropriate mitigation measures. A questionnaire has been compiled that includes 38 factors that create possible risk events during shipping by sea. The risk matrix is used as the basis for quantitative risk analysis to identify the most important risks that greatly affect the operation of thermal power plants and indicate solutions to control risks. Research analysis and risk assessment based on the survey questionnaire, achieved the following results: 1) Recognizing that, there are 27 major risks affecting the transport of coal by sea; 2) Scientific rating of the effect of all risks to sea transport of coal; 3) Make recommendations that can reduce or eliminate influencing factors. This study provides a valuable reference to help the investor and the contractor complete the plan, ensuring the benefits for the parties involved in the contract to perform the operation of the thermal power plant.
