“…The equation formulated was in a form of exponential function. Method III was the log approach where the regression analysis was performed using the logarithms of parameters as shown in Equation 5and then transformed to format of Equation 6 [7].…”

“…LOGEST is one of the regression analysis functions in Microsoft Excel to generate an exponential curve that fits the data [5]. The log approach is similar to LOGEST approach which generates an exponential curve with slight difference [7]. The LOGEST and log regression equation generated are as in the form shown in Equation 2 and 3, respectively; y=β 0 +β 1 x 1 +β 2 x 2 +β 3 x 3 +β 4 x 4…”

Reliability is one major concern in the Oil and Gas industry to date. Reliability issues due to aging and increasing environmental loading are common for jacket platforms in Malaysia. Authors have studied system reliability assessment on existing jacket platforms in Malaysian waters and concluded that the current reliability assessment in the industry practice is tedious. The scope of the study includes regression analysis using three different methods to generate regression equation which could serve as a simplified reliability prediction model. Regression equations generated in this study seek to improve the current reliability assessment of jacket platforms in Malaysia by providing means for screening process before proceeding to tedious reliability analysis.

“…Finally, the sensitivity of the RSR towards the independent variables was studied. Ng et al (2011) performed nonlinear regression analysis on a semi-submersible platform to obtain the response amplitude operator (RAO) based on parameters such as wave frequency, member diameter, and member draft. The nonlinear regression analysis was simplified to become linear regression analysis utilizing the logarithms of parameters (Eq.…”

In this study, the technical papers on structural condition assessment of aged fixed-type offshore platforms reported over the past few decades are presented. Other ancillary related works are also discussed. Large numbers of researches are available in the area of requalification for life extension of offshore jacket platforms. Many of these studies involve reassessment of existing platforms by means of conducting pushover analysis, a static nonlinear collapse analysis method to evaluate the structure nonlinear behaviour and capacity beyond the elastic limit. From here, the failure mechanism and inherent reserve strength/capacity of the overall truss structure are determined. This method of doing reassessment is described clearly in the industry-adopted codes and standards such the API, ISO, PTS and NORSOK codes. This may help understand the structural behaviour of aged fixed offshore jacket structures for maintenance or decommissioning.
