THE CHERLOC PROJECT: AN EXPERIMENTAL CASE STUDY OF MARINE STRUCTURES COMBINING ENGINEERING AND BIODIVERSITY

Résumé

A topical issue for coastal structures is the development of innovative solutions combining functional requirement and ecological improvement. The CHERLOC collaborative project seeks to meet engineering design needs for coastal structures while preserving the ecological habitat of coastal areas and develop biodiversity on marine infrastructures. The aim of the project is to perform in-situ coastal protection experiments designed via a cross-disciplinary engineering, biodiversity and societal approach. Two pilot sites were set up in the Normandy region Ouistreham and Cherbourg. The Cherbourg site involved the installation of new artificial concrete block armour along a damaged trunk section of the existing Eastern port breakwater. These blocks are more specifically a new block armour known as "Double-Cube (DC)" and a new generation of toe blocks called ACCROBERM™ II, which are designed to replace "classic" toe rocks and limit direct and indirect environmental impacts. The design aimed to achieve a limited footprint on the seabed and an enhanced cavity. This paper gives an overview of the design conditions of the experiment, details the construction aspects of the pilot site, and points out the first lessons learned and the outcomes regarding stability and biodiversity surveys after more than one (1) year of the experiment.
