A model for reliable fatigue life predictions of offshore structures is the object of a new research project in which researchers from DTU Mechanical Engineering and the University of Cambridge collaborate. The goal is to provide reliable estimations of service lifetime by developing a new physically-based fitness-for-service methodology.

A new DHRTC funded project aims at providing the Danish oil and gas industry with more reliable and accurate ways of estimating service lifetimes. The project builds upon recent scientific achievements, and aspires to predict fatigue and fracture in engineering components by means of a new generation of models that account for the underlying physical mechanisms of material failure. These mechanistic models enable accurate computer predictions of service-life conditions.

The project aims at extending the success of virtual testing to the Danish oil and gas industry. The use of virtual models minimizes expensive experimentation and optimizes material selection and inspection planning. The economic costs can be substantially reduced by accurately predicting when a crack begins to form under specific loading and environmental conditions and further, how long it takes before the crack is critical.

Professor Christian Niordson from DTU Mechanical Engineering and Research Fellow Emilio Martínez Pañeda from University of Cambridge are two of the researchers behind the project, and both are very optimistic about their coming project and the results it can bring.

“Virtual testing has the potential to drastically optimize material selection and fitness-for-service assessment”, states Emilio Martínez Pañeda.

The project is in line with the Cost Transformation 3 (CTR 3) work programme at DHRTC. The research team includes Professor Christian Niordson and Professor Rajan Ambat, DTU Mechanical Engineering, Research Fellow Emilio Martínez Pañeda, University of Cambridge, and PhD student Philip Kristensen.
