In the design process of offshore platforms in Indonesia, random variables of load and material strength must be taken into account. To cover this uncertainty, the industry standard in Indonesia is to use the American Petroleum Institute Recommended Practice 2A-LRFD (API RP2A-LRFD) load factor. To further assess the reliability of the structure, a structural design analysis was carried out according to the provisions of API RP2A-LRFD, and the Monte Carlo method was used to determine the reliability index of the structure. This would help to determine whether the structural design is conservative or not according to the LRFD load factor. Additionally, four important members of the structure were selected to assess the reliability of the structure against the random variables of load and material strength. With the reliability index, it will be possible to have an overview of the structural design and ensure that the structure is safe and secure against environmental conditions in Indonesia.
