Royal Boskalis Westminster N.V. has been awarded the contract for the protection of a 7 kilometre stretch of coastline in Cotonou, Benin in Western Africa. The contract was awarded by the Ministry of urbanism, habitat and sanitation of the Republic of Benin and has a value of more than € 35 million. The project started mid 2012 and was completed in 2 years, mid June 2014.

The project scope encompasses the re-construction of an existing breakwater and the construction of seven new groins and a revetment into the sea to prevent further erosion of the coastline.

The (re-)construction was executed with dry earth moving equipment. The groins were constructed using 530,000 tonnes of rock sourced from local quarries, 2441 Xblocs and over 32.000 m2 geotextile.

This coastal protection project is driven by population growth and climate change.
