capable of dredging hard soil and able to work in water depths of more than 100 m.“The design of the Bonny River is inspired by a drive to continuously innovate from an ecological and efficiency perspective," said Jan Gabriel, Head of the Technical Construction and Conversion Department at DEME Group. Bonny River is driven by a pair of Schottel Controllable Pitch Propellers type SCP 129 4-XG with an input power of 8,000 kW each and a propeller diameter of 4.5 m. It reaches a speed of approximately 16 knots. Beyond this, maximum maneuverability and propulsion efficiency are provided by

DEME Group's GSR (Global Sea Mineral Resources) exploration activities in the Clarion Clipperton Zone (CCZ) during the company's 2017 Pacific campaign narrowed in on three major elements: resource assessment, technology and environment.To verify resource estimates undertaken during GSR's 2014 and 2015 campaigns, nodules were collected using deep-sea dredges and box cores.The technological aspects involved the deployment of Patania I, the first tracked soil testing device vehicle to reach and travel the seafloor at depths of more than 4,500 m. The vehicle is the first of a series of three

First Monopile Loaded at Sif’s Maasvlakte 2 Location

Sif loaded its first monopile on board a seagoing vessel. The ship in question is the Innovation, a heavy-lift jack-up vessel owned by Geosea, part of the Belgian DEME Group. It was also the first job handled at the new section of Maasvlakte 2’s deep-sea quay (port number 8317). Monopiles are used for the foundations of offshore wind turbines. They can weigh up to 1,000 metric tons apiece. All in all, four monopiles will be loaded for transport today. Together with the so-called ‘transition pieces’: connecting sections that are used to join the turbine towers to the monopiles.
