Risk assessment is an activity to measure the risk level in a system and equipment. The purpose is to reduce the serious damage to safety, environment, and financial losses by the company if the equipment is damage or fail. Analysis and calculation has been done in order to find the risk level in reference by DNV RP-G101 Code Risk Assessment of Offshore Topside Static Mechanical Equipment. As the case studies are equipments in Separation and Stabilization unit in Central Processing Production (CPP) Platform North Belut that located in Blok B, Natuna Sea. The purpose of these risk calculations is to get the risk level in the studied equipments. Moreover, exercise to some parameters also applied in this thesis to know and get the effect to the PoF and CoF. The result from screening assessment level show that inlet gas separator bottom, inlet gas separator top, condensate separator bottom, and condensate separator top have a high risk level that will continue to detail assessment. And the result from detail assessment show that, equipment gas separator top have safety and economic consequence value 2,078 and US$ 11.618.216 and PoF 0,00485. And the condensate separator top have a value 0,579 for safety consequence and US$ 21.870.980 for economic consequence, and the PoF value is 0,00399. The exercise to some parameters that has been done, show the linear relation between pressure and dispersion modeling, and also between corrosion rate and the value of the probability of failure .
