Project Summary

Delivering large-scale, locally manufactured Reef cubes® in Sénégal

ARC marine delivered a large-scale artificial reef deployment off the coast of Saint-Louis, Sénégal, working with bp, PETROSEN, Kosmos Energy and STAPEM as part of the Greater Tortue Ahmeyim (GTA) project’s social investment programme.

The project involved the manufacture and deployment of 403 Reef cubes®, all produced in-country using ARC marine’s RIB (Reef cubes in a Box) system. This approach employed a local workforce, used regionally sourced materials and reduced transport emissions, while ensuring the reef structures were suited to the site’s physical and ecological conditions.

The deployed Reef cubes® deliver a total of 24,634 m² of new reef area, creating stable, complex habitat intended to support fish populations and wider ecosystem recovery, and demonstrating how locally manufactured reef solutions can be delivered efficiently at scale.

Challenge

Coastal and offshore developments increasingly seek to deliver measurable biodiversity and community benefits alongside infrastructure investment. However, artificial reef projects are often constrained by high transport emissions, limited local involvement and designs that are poorly adapted to local environmental conditions.

For projects operating in emerging markets, there is a clear need for reef solutions that can be manufactured locally, delivered at scale and integrated efficiently, while supporting long-term ecological function and local economic participation.

Solution

ARC marine deployed its RIB (Reef cubes in a Box) system to enable in-country manufacture of artificial reef structures in Senegal. Using RIB, 403 Reef cubes® were produced with 15 locally employed personnel using regionally sourced materials, delivering reef structures suited to local physical and ecological conditions.

ARC marine delivered several key elements of the project workflow:
• Ecological baseline assessment
• Nature-Inclusive Design
• In-country manufacturing through RIB
• Installation guidance and offshore equipment
• Framework for long-term monitoring

The reef is now complete and has been designed to provide stable, complex habitat that supports fish populations and wider ecosystem recovery.
