... concentration factor, reliability analyses are conducted to calculate the reliability safety index of the panel based on a strain-based limit state. The structural failure can then be directly related to the reliability safety index. The reliability procedure is demonstrated in an example of a highly deformed...

... from existing tankers or purpose-built. However, FPSOs have their own unique characteristics, including various operational requirements. In addition to that, the expectation of safety and economic aspects of FPSOs require an optimized structure to be designed. This calls for reliable structural...

... with this. In order to ensure the consistent safety level for assessment of fatigue failure, the design fatigue factors (DFFs) to be used for fatigue design should be dependent on the analysis procedure and premises used. In the present paper, an assessment of appropriate DFFs for piles subjected to dynamic actions...

... of innovation or when only qualitative or vague statements can be made. The model is also a modular representation of uncertain knowledge due to randomness and vagueness. This makes the risk and safety analysis of offshore engineering systems more functional and easier in many assessment contexts. A case study...

...Arash Nobahar; Shawn Kenny; Tony King; Richard McKenna; Ryan Phillips In cold environments, marine pipelines may be at risk from ice keels that gouge the seabed. Large quantities of material are displaced and soil deformations beneath a gouge may be substantial. To meet safety criteria, excessive...

Examples of users of such criteria are the national and international regulators that implement safety related regulations and industrial companies that operate in an industrial self...
