In dredging, the hydraulic transport of solids is one of the most important processes. Since the 50’s many researchers have tried to create a physical mathematical model in order to predict the head losses in slurry transport. These models are Durand, Condolios, Gibert, Worster. Zandi & Govatos, Juf
The first commercial offshore wind measurement campaign using floating LiDAR in European waters has kicked off in the Irish Sea. FLiDAR NV has deployed one of its innovative LiDAR buoys for DONG Energy in the southern East Irish Sea. DONG Energy, the world’s leading offshore wind developer, selected
The first R115, which is a machine rated at 99kW, will be launched in Pisa on June 19th at a marina inside the “Darsena dei Navicelli”. After final assembly, most likely towards the end of July, the machine will be towed to the Punta Righini WEP test site and will stay there for a few […]
M-I SWACO, a Schlumberger company, today announced the introduction of the MD-2† dual-deck shale shaker. When combined with DURAFLO† composite screens, the MD-2 shaker provides optimal solids control performance for drilling applications. “As well construction costs continue to rise, today’s shale s

In recent years, Chinese dredging companies have been actively taking pail in the domestic and foreign dredging market. They have built a large numbers of cutter suction dredgers, CSDs & trailer suction hopper dredgers, TSHDs with the Chinese dredging equipment makers developing and improving a lot.
When dredging hard cohesive soils such as clayey silt, mild clay and clay, traditional teeth such as chisel teeth can only penetrate to a shallow depth of the soil layer and bear more cutting resistance, which directly affects the dredging efficiency of the trailing suction hopper dredger. In order
REMU Big Float is a unique amphibious excavator for the most challenging environment like swamp, shoreline, waste ponds and canals. Patented pontoon undercarriage that can be narrowed, enables easy transportation along public roads. REMU Big Float is instantly ready to use without any assembly at th
Van Oord’s powerful cutter suction dredger Athena was built by IHC Dredgers for dredging in hard soil. The strong vibrations on this type of dredger are notorious for their negative effects on the working and living conditions on board. Van Oord’s global dredging experience, IHC’s drive to build inn
VSMC recently signed two separate contracts to lay and bury export cables for the Westermost Rough (ENG) and Humber Gateway (ENG) wind farms. With these latest projects, VSMC strengthens its strong position in laying and burying electricity cables in and to offshore wind farms. Westermost Rough Offs
Siemens Mechanical Drives has supplied pioneering tidal technology company Tidal Energy Limited (TEL) with gear units that will be part of the DeltaStream tidal stream generating device due to go on a 12-month trial in Ramsey Sound early in 2014. It will be Wales’ first commercial-scale turbine. The
After more than a year of preparations and near-shore testing, the Fishermen’s Energy Wind Sentinel buoy was relocated from a test site near Atlantic City to an offshore area leased from the U. S. Department of Interior’s Bureau of Ocean Energy Management (BOEM). Located eleven miles east of Ocean C
Increased activity in the oil and gas and petrochemical sectors, together with improved regulatory compliance, is boosting revenues in the otherwise mature and slow-growing Western European gas detection market. Growth during the short-term is also driven by the upgrade or replacement of existing ga
A new fiber-optic monitoring system developed through a Space Act Agreement between NASA and Astro Technology Inc. of Houston is helping to increase safety for workers and reduce the risk of leaks and spills on two oil platforms off the coast of West Africa. The technology also has potential future
