Effect of Crack Propagation on Condition Assessment of Aged Offshore Jacket Platform

The project will focus on how fatigue crack could influence the overall stability and performance of a jacket platform. Offshore structures are vital for continuous hydrocarbon exploration. Fatigue and crack growth on the structural members of jacket structures have been recognized to be one of t...
