| Summary: | Oil and Gas Industry as majority of the jacket platforms in Malaysian
waters to date, have exceeded their design life. Reliability of a jacket platform can be
evaluated through Structural Reliability Analysis. Conventional metocean
consideration uses 100 year return period wave height associated with 100 year return
period current velocity and wind speed. However, recent studies show that for
Malaysian waters, the proposed metocean consideration should be 100 year return
period wave height associated with 10 year return period current velocity and wind
speed. Hence, this research studies the effect of different metocean considerations to
system based reliability of the jacket platforms in Malaysian waters. Besides, the
significance of parameters such as metocean considerations, pile soil interaction
(PSI), and environmental load direction are observed in a sensitivity study in |
