“…It should be noted that this assumption was not considering any other possible hazards such as accidental damages and pile related failures. In this study, it was observed that the average corrosion condition relatively simulated the calm waters of Malaysia where the environmental condition is much safer compared to the North Sea region or the Gulf of Mexico [44].…”

Continuous assessment of aged offshore structures is becoming extremely important to avoid any hazardous consequences throughout their design life. In Malaysian waters where most of the offshore structures are jacket platforms, it was found that many of these structures are currently operating beyond their design life. With continuous corrosion taking place, structural reliability and operation will be affected. Therefore, for the safety evaluation, this study focuses on the reassessment of an existing aged jacket platform in Malaysian waters pertaining to corrosion effect. In this study, pushover analysis was carried out to determine the ultimate strength of the corroded jacket platform by quantifying the reserve strength ratio value. Two different time-dependent corrosion wastage models were used in the present study to simulate the corrosion behaviour at the splash zone of the jacket platform. It was observed that average corrosion condition relatively simulated the calm waters of Malaysia and by applying this corrosion, the jacket platform can withstand the environmental load acting on it. The results developed in the present study will be useful for future study in predicting and modelling corrosion tolerance of jacket platforms in Malaysian waters.

“…If P c remains greater than P plt or P stf , failure is assumed to be by stiffener tripping or local plate failure depending on which component load shortening curve peaks first. Paik and Thayamballi (2003) gives a simple equation to estimate peak strength of a combined element (P p-s ) by combining the plate and stiffener strength using the proportional area of each component:…”

“…A similar account is presented for the discrepancies between results from the Smith interframe collapse method [14], where the strength data for the stiffened-plate and hard-corner elements may be extrapolated from generic curves stored within the software or bespoke data calculated and input by the user before analysis. However, Paik et al [7] provides a total of six possible failure modes that may exist when considering the failure of a grillage arrangement, whereby the "real ultimate strength is the minimum value of ultimate strengths obtained from the six solutions." [16].…”

“…This method maintains the assumption that interframe collapse is the prominent mode of failure of a longitudinally stiffened and transversely framed vessel, originally presented by Caldwell [6]. For progressive collapse analysis of ship hull structures, discretisation is commonly made into an assembly of plate-stiffener combination units [7] rather than the separate plate and beam-column elements commonly used in ISUM [8]. ISUM and ISFEM differ in that ISUM elements are solely based on analytical formulations or solutions, while ISFEM elements are formulated by taking advantage of both analytical solutions and Finite Element algorithms, which is considered to be more useful for modelling more complex structures [5].…”

It is vital to be able to rapidly assess damaged ship structures. This ensures the safety of personnel and facilitation of the most effective repair or recovery. Interframe progressive collapse analysis has been used as a method for rapid assessment for vessels but its suitability for application to damaged vessels has been questioned, due to the limited failure modes assessed and modelling assumptions required when implementing the method. To reduce the cost and increase the effectiveness of the recovery of a damaged vessel, it will be important to more accurately assess the structure by determining the correct failure mode. This paper presents a study on the use of progressive collapse analysis to model damaged box girders which assesses the structure across multiple frame boundaries. The study shows that while progressive collapse analysis can be applied in the assessment of damaged box girders, implementing the newly proposed assessment allows greater accuracy in the calculation of the collapse strength through capture of the true mode of failure. This new method will allow the effects of the damage on surrounding structure to be captured which can influence the deflection shapes that will lead to collapse of the structure.
