DETERMINATION OF RESERVE STRENGTH RATIO FOR AN EXISTING JACKET PLATFORM

Structural Analysis Computer System (SACS) software was used to model and carry out pushover analyses to determine whether an existing jacket platform is fit for continued usage. Through different combinations of dead loads, live loads, and storm wave and current directions, an RSR as low as 2.64 and as high as 4.00 was obtained. This variance of results showed the effects different live loads, and storm wave and current directions had on the RSR of a jacket platform. According to API RP-2A, a high consequence platform is required to have an RSR of at least 1.6. Hence the platform is deemed to be fit for continued usage.
