DEME informed that the sea trials of its LNG-fueled trailing suction hopper dredger Bonny River, have started in the South China Sea. The dredger is able to dredge very hard soil, as well as work in water depths of up to 100m.

Thanks to the hull's design, the 'Bonny River' with its transport capacity of 24,000 tonnes, has a limited depth when loaded, making the ship capable of coastal protection assignments, even in regions with shallow beaches.

In addition, the ship has a second, shorter suction pipe for dredging works on a harder seabed. With this 75 tonnes draghead, the 'Bonny River' is able to remove hard soil which was not dredgeable in the past.

As DEME said, the vessel will minimise the turbidity generated by process water and enables dredging in environmentally sensitive areas. Furthermore, the hydrodynamic hull and the dual-fuel engines, both diesel and LNG, ensure optimisation of the fuel consumption and a limited CO2 footprint.

The ship was built by COSCO at its shipyard in Guangdong, China, and was launched in April 2018.
