Commonly used standards for offshore platform design are proposed by American Petroleum Institute (API) which adapts environmental conditions in Gulf of Mexico. Due to the more relatively extreme conditions in Gulf of Mexico, the application for Indonesian waters needs to be reviewed. Standards proposed by API are aimed for jacket structures. The load transfer in monopod structure is different with jacket structure, where monopods distributes both horizontal and vertical load to one member (Ronalds et. al., 2007). Case studies were carried out for unbraced monopod structures located in Java and Natuna Sea by reviewing the value of structure’s reliability index (β). The result shows that structure designed with LRFD environmental load factor of 1.35 in Java Sea, has met the recommended reliability index value proposed by DNV (β = 3.72). Meanwhile for structures in Natuna Sea with the same environmental load factor, the reliability index value is still below the recommended value (β = 3.14).
