Fugro has completed a geotechnical site characterization project for DRA Global as part of the proposed expansion of the port of Richards Bay in South Africa.

DRA Global contracted Fugro to acquire critical seabed geodata required for the completion of preliminary engineering and design works. The project began with a cross-continental mobilization of marine assets from Bangladesh and UAE to Richards Bay and was safely delivered despite challenging ground conditions and ongoing COVID-19 restrictions.

The very soft soils encountered at depths of more than 40 meters below the seafloor required an innovative solution for positioning the two geotechnical drill rigs safely, so Fugro mobilized two bespoke modular self-elevating platforms (SEPs) to acquire high-quality geodata in a wide range of water depths. Their experienced staff, combined with adaptable marine assets and tooling, enabled Fugro to deliver DRA Global’s requirements in full and avoid any data gaps that could have led to an over-engineered design and ultimately higher construction costs.

“Fugro performed well under difficult circumstances, including challenging site conditions and intense focus on environmental management in sensitive areas, all while working in an operational port,” said Cobus Rossouw, principal marine engineer at DRA Global. “Their robust safety management systems resulted in an investigation completed without a single lost-time incident.”

Fugro has secured a contract with Energinet to provide floating wind lidar measurements for what an offshore artificial energy island, which is being constructed for the Danish Government.

Fugro will install and operate four SEAWATCH wind lidar buoys at two locations, Energioe Nordsoen and Energioe Baltic, that will act as hubs connecting several offshore wind farms.

Starting this month October, the buoys will record continuous wind measurements for a minimum of one year to support wind-resource mapping for the two islands, and the engineering and design of the future wind farms. Fugro is already performing geophysical surveys for the Energy Island project under a separate contract to provide Energinet with a reliable de-risked site interpretation.

The SEAWATCH wind lidar buoy can record wind measurements up to 250 meters above sea level, and wave measurements and current profiles down to the seabed. The buoy also acts as a multipurpose platform for additional metocean sensors and, on this project, will be fitted with sensors to capture geodata on environmental impact parameters.
