This ebook offers a examine for the decision of environmental load elements for Jacket structures in Malaysia and a technique to figure out the existence extension of getting older systems. The simplified tools defined right here can be used for picking out not just structural reliability but in addition protection elements. Its content material is very attention-grabbing to layout and upkeep engineers who're operating in offshore or onshore industry.

2 Jacket Platform Design in Malaysia In Malaysia, API RP2A WSD is used by offshore design and fabrication industry along with PETRONAS technical standard (PTS), for local environmental load parameters. 35. The application of environmental load factors which is optimised for GOM offshore region and materials may be not be reasonable for Malaysian waters . The calibration of load factor has never been done so far in this region. 3 Uncertainty Load and resistance are considered as random variables.
Chapter 4 deals with statistical analysis of uncertainty of resistance variables. Resistance uncertainty of geometric and material variables for Jacket platforms is determined, and this is not available in this region. Resistance model uncertainty is also not reported in this region before. ISO uncertainty mathematical models are used to find the model uncertainty of component and joint stresses. e. material resistance, is also determined. Chapter 5 deals with load variables. The site-specific load data for three regions are used to model the load uncertainty variables which have not been reported in previous studies.
