... in order to end-up with a diagnosis has contributed in this direction. Over time, these activities have evolved into a process that is observing structural integrity complemented with damage assessment and is commonly known as health monitoring (Chang et al., 2003) or by the 1378 Proceedings of the Twenty...

... ABSTRACT A number of offshore jacket structures worldwide have already exceeded their designed lifetime. As a result, there is a growing interest to extend the life of the jackets by Structural Health Monitoring (SHM) to ensure the structural integrity, safe operation, failure prevention...

... that there are locally plastic deflections. Even so, the global structural integrity of the shale shaker room is not threatened by the local plastic deflections. The risk that the shale shaker room would be collapsed due to the explosion is low. SHIP COLLISION RISK EVALUATION There may be two kinds of the energy...

...) on its dynamic behavior and its structural integrity is investigated. Nonlinear pipe-soil interaction of the part of the pipeline lying on the seabed is considered. A global buckling check is also implemented. The effect of each examined factor/parameter on the dynamic behavior and the structural...

Ranking and quantification frisk with influence on the pipeline structural integrity forms a major basis for an efficient and reliable operation of the system. Objectives Pipeline transport systems...

... in approach to the demonstration of life cycle integrity with far-reaching implications for design, fabrication, operation and decommissioning. These fundamental changes have required the approach to the assurance of the structural integrity of older structures installed prior to the implementation...

... ABSTRACT This paper focuses on (analysis of) structural integrity when (re)assessing jacket type of platforms subject to wave-in-deck loads. Relevant topics when evaluating structural integrity can be split into two main groups, which are given attention to herein: Environmental (mainly wave...

... at the through-thickness stage; data on the performance of this type of cracked joint are very limited. The implications on structural integrity of these factors are assessed. There is limited information on the effect of TTCs on the structural integrity of welded joints in frame structures. Additionally...

... and changing of the contract strategy. At the same time the level of confidence in the structural integrity of NAM's offshore installations improved as well. Furthermore the spin-off of enhanced offshore safety to the workforce is discussed. INTRODUCTION The first NAM platform was installed in 1974...
