DEME, an international group of specialized companies involved in complex marine engineering works, said in the latest release that sea trails of their newbuild 15,000m³ trailing suction hopper dredger (TSHD) Bonny River has officially started near Dawanshan Island in the South China Sea.
“The technically smart designed vessel combines various innovative features, such as the capability to dredge very hard soil and the ability to work in water depths of up to 100m, ” DEME said.
The TSHD Bonny River was launched in April 2018 at COSCO Guangdong Heavy Industry shipyard in China.
According to DEME, the dredger will be able to minimize the turbidity generated by process water and enables dredging in environmentally vulnerable areas.
The hydrodynamic hull and the dual-fuel engines (diesel and LNG) will ensure further optimization of the fuel consumption and a minimal CO2 footprint.
Thanks to the hull’s optimized design, the dredger will have a transport capacity of 24,000 tonnes. Having a limited depth when loaded, the newbuild will be highly suitable for coastal protection assignments, even in regions with shallow beaches.
