Royal IHC has been awarded the contract for the design, construction and delivery of a multifunctional dredging vessel to DEME in Belgium. Named the BONNY RIVER, the 15,000m3 trailing suction hopper dredger (TSHD) will be supplied with an extended suction pipe, and an additional suction pipe with heavy-duty rock draghead, enabling the vessel to operate in hard soil areas.
The BONNY RIVER will be the first vessel in DEME's fleet with a closed process water circuit. This minimises the turbidity generated by overflow water and enables the vessel to dredge in environmentally vulnerable areas.
The hydrodynamic hull and the dual-fuel engines (diesel and LNG) ensure further optimisation of fuel consumption levels and a minimal CO2 footprint. Due to its limited depth when loaded, the BONNY RIVER is also suited to operations in shallow water.
The TSHD will carry a 'Green Passport' and a 'Clean Design' classification, a certification for owners and contractors who make the conscious decision to build and operate their vessels in an environmentally friendly way.
The BONNY RIVER – named after the Nigerian river – is the third TSHD that DEME currently has on order with Royal IHC, together with the MINERVA and SCHELDT RIVER. "We are very proud that DEME has ordered all their TSHDs since 1992 from IHC," says Royal IHC CEO Bram Roelse. "This latest order proves that our turnkey deliveries are highly competitive in the international market."
IHC will provide the turnkey delivery of the entire vessel, including the dredging, electrical and hydraulic installations and the automation system. Construction will take place in Guangdong, China, under IHC's supervision.
