A 6-month research project into the decommissioning of gravity based structures was nominated for the Dutch Marine Contractors award (Waterbouwprijs) 2020.
Tessy Donkers and Thomas van Deursen, graduation students in civil engineering at Avans University for Applied Sciences, carried out their final thesis at Enersea, based in Schiedam, the Netherlands.
The study was conducted with aid of Petrogas E&P NL and Neptune Energy, both owners of gravity based structures.
On 15 October, the winner was announced during the Dutch Marine Contractors day (Waterbouwdag) which took place as a virtual event this year. Donkers and Van Deursen ended in the top 3 of nominees and finally won this year’s award.
The jury was impressed by the way in which Donkers and Van Deursen combine a broad, comprehensive consideration of the problem with detailed calculations to end up at a preferred approach through a multi-criteria analysis.
