Interview: Tiedo Vellinga – ‘There should be a shift in the way of thinking about designing infrastructure’
A newly appointed Professor Emeritus at TU Delft and former project manager at the Port of Rotterdam Authority, Tiedo Vellinga discusses his role as a bridge between academia and practice and its impact on the direction of port development.
Safe navigation through ports and waterways is determined by the space available under a ship's keel, but a seabed of fluid mud can get in the way.
Amongst all the studies done at the MV2 Port of Rotterdam expansion, none was more exciting than the discovery of the Middle Stone Age civilisation that flourished on the Maas-Rhine delta 9,000 years ago.
TNO’s acoustic surveys of dredgers during all phases of the dredging cycle showed that permanent hearing threshold shift was not exceeded in any cases studied or in any species in question.
Given the inter-dependence of the underwater food chain from benthic fauna and algae to shells, worms, fish and birds, a new modelling strategy was instituted to evaluate the effects of enhanced silt concentrations during dredging.
