IHC launches DEME’s latest in China

This green flagship for DEME will be able to carry out challenging projects with minimal impact on the environment

The Belgian DEME Group’s latest trailing suction hopper dredger 'Bonny River' has been successfully launched at Royal IHC’s partner yard COSCO Guangdong Shipyard in China.

The vessel has a hopper capacity of 15,000m3 and is capable of dredging to depths of 102m. It is a technically ‘smart designed’ vessel, combining the capability to dredge hard soil through a heavy duty suction tube whose XXL length enables such deep dredging.

Environmentally friendly aspects such as minimising turbulence with its closed process water circuit, installation of dual-fuel engines and CLEANSHIP and Green Passport notation making Bonny River a most versatile TSHD. This green flagship for DEME will be able to carry out challenging projects with minimal impact on the environment. Bonny River is due to be commissioned and operational in the near future.

Royal IHC has also secured an order from the Engineering Authority at the Egptian Ministry of Defence for the construction of ten IHC Beaver cutter suction dredgers and five Delta MultiCraft 1050 workboats.

The order also includes three IHC Multi-Booster stations , each delivering 895kW of power, as well as ten 1,500m length HDPE floating pipelines. IHC will also provide a comprehensive training package for crew and staff.

“The CSD’s will be deployed for the maintenance of Egypt’s lakes and waterways, says IHC’s srea sales director Africa, Rogier Kalis. “This includes removal of excessive sedimentation, deepening of waterways and environmental dredging. We are proud to contribute to the sustainable development of the country’s important marine infrastructure.”

Meanwhile, Royal IHC has been awarded a contract for the delivery of dredge pumps for new vessels joining the fleet of the Jan De Nul Group. The agreement incorporates two onboard double-walled dredge pumps for the operator’s new 18,000m3 capacity trailing suction hopper dredger as well as onboard single-walled dredge pumps for two other 6,000m3 capacity trailers.

“We are delighted that we have secured another order from Jan De Nul Group, says Royal IHC CEO Dave Vander Heyde. “For the past 20 years the company has continuously extended its TSHD fleet and it is testament to our partnership that the majority of these vessels are equipped with IHC dredge pumps.”

For the 18,000m3 capacity hopper, the double-walled dredge pumps have been designed to deliver a total installed power of 7,000kW per pump. This will enable them to discharge 33 bar pressure when operated concurrently. The single-walled dredge pumps for the smaller hoppers will deliver an installed power of 4,000kW and provide a discharge pressure of up to 11 bar. The two double-walled pumps will also be equipped with IHC’s latest Curve technology.
