Evaluation of seismic behavior of offshore platforms is one of the important design steps in seismic regions. Nevertheless, because of complication and time cost of these methods, engineers usually do not study them deeply. Endurance Time (ET) method is a good solution for this problem. In this method, with acceptance of a reasonable region of errors, the time of analysis can be reduced conside...
In order to predict the residual life of offshore platforms and establish efficient schedule for underwater inspection and repair, it is necessary to estimate the fatigue crack growth rate in tubular joints properly. Linear Elastic Fracture Mechanics and Stress Intensity Factor are applicable tools for evaluating growth rate of existing fatigue cracks in offshore tubular joints. In the past sev...

The UK has an abundant offshore wind resource with offshore wind set to grow rapidly over the coming years. Optimisation of energy production is of the utmost importance given the high installation and maintenance costs of offshore turbines; accurate estimates of wind speed characteristics are critical during the planning process. While operational assessment methods which rely upon in-situ obs...
The main objective of this project is to develop a generic framework which will set the basis for achieving more consistent system reliability assessments. The main steps involved in a system reliability assessment, together with the key technical and philosophical issues, will be identified and examined. Their interrelations and relative significance will be assessed in order to link them toge...
