Guaranteeing the structural integrity of an offshore platform
Context & Issues

The Total Group, which is operating the oil field until 2039, called on Artelia’s structural engineering experts to extend oil extraction activities at this site.

Artelia analysed the steel structure of the platform in order to check the state of stresses, estimate the level of fatigue in the tube intersections, and calculate remaining reserves with respect to ultimate capacity. 

The studies performed required highly specialised skills, tools and programs in the field of material strength calculation.

Recommendations were formulated to optimise the underwater cleaning works and make it possible to retrofit the platform with additional equipment.
