The Bremen-situated planner and operator wpd takes positive stock for the construction of the offshore windfarm Butendiek. “We are about to complete pile driving, we are well within our time schedule and we have fallen short of the predefined sound levels”, said Achim Berge Olsen, managing director of Butendiek and wpd offshore. Of the 80 foundation […]
By Alexandre Crochelet, Senior Engineer at G-Octopus, a Cathie Associates Company Pile Driving Monitoring (PDM) during driving and Pile Dynamic Testing (PDT) are widely used in onshore and offshore construction to ensure the structural integrity of the piles during driving and achieve a safe and economical pile installation. PDM helps in assessing the pile behaviour […]
G-Octopus, a Cathie Associates company, is rebranding in order to bring into focus its piling solutions for the renewable energy and oil & gas industries.
U.S. National Oceanic and Atmospheric Administration (NOAA) has sent a letter to BOEM expressing concern for the possible negative impacts the Vineyard Wind project could have on fisheries, marine life and habitats. The letter represents NOAA's public comment on BOEM's Draft Environmental Impact Statement (DEIS) for the 800MW offshore wind project in Massachusetts. NOAA stated that "the […]
Royal Belgian Institute of Natural Sciences (RBINS) has published a report on the environmental impact of offshore wind farms in Belgium, which has 870MW in operational wind turbines in its part of the North Sea as of 2016 and plans to reach 2.2GW by 2020.
The offshore wind project developed by the Iberdrola-led Ailes Marines consortium in the Bay of Saint-Brieuc, France, is set to receive the administrative authorisation in the coming days, according to French Ministry of the Environment, Energy and the Sea.
Hydrohammer S-4000 Installs First Monopiles The S-4000 Hydrohammer pile-driving system installed its first monopiles at an offshore wind farm in the North Sea, IHC IQIP, a business unit of Royal IHC which recently launched the system, reports. Siemens to Buy Adwen as Part of Gamesa Merger? Reportedly, Siemens is likely to buy Adwen, a joint […]
JASCO Applied Sciences, under subcontract to Tetra Tech Inc., is providing underwater acoustic measurement and monitoring services to Deepwater Wind during the installation of the Block Island Wind Farm. JASCO is conducting field data acquisition and subsequent analysis and interpretation for short- and long-term studies of noise from pile driving and related construction activities. The […]
The U.S. Bureau of Ocean Energy Management (BOEM) has begun a new study to conduct real-time, independent observations and data collection during construction of offshore wind turbines. Field work took place in August and September of this year through the Real-time Opportunity for Development Environmental Observations study, or RODEO, which is taking direct measurements of […]
Offshore WIND's photo of the day: Full steam ahead at the Block Island offshore wind farm site. Deepwater Wind started building the first offshore wind farm in the U.S. yesterday, when the installation vessel Weeks 533 and a barge carrying wind turbine foundations met three miles (4.8 kilometres) off Block Island with several crew transfer vessels and tug boats. […]
Disturbance Effects on the Harbour Porpoise Population in the North Sea (DEPONS) project has yielded some preliminary findings on the effect of offshore wind farm construction on harbour porpoises. "Although the results should be considered preliminary, the patterns generated by the current version of the DEPONS model did not suggest any clear, long-lasting effects of pile-driving […]
A consortium of five international energy companies has taken the initiative to launch the DEPONS (Disturbance Effects on the Harbour Porpoise Population in the North Sea) research project, which aims to study how the population of harbour porpoises in the North Sea is affected when new offshore wind farms are built. Spearheading the consortium is […]
KCI has been entrusted with the installation assistance of tripods series 3, 4, 5 and 6 for Global Tech I Offshore Wind Farm in the German part of the North Sea. The installation of the first tripods, weighing approximately 900 tons each, started in September 2012. The tripod installation is still ongoing. As the soil […]
The scope concerns one met mast and its foundation for environmental monitoring, designed, manufactured, delivered, transported, installed, commissionned for the offshore wind farm site of Courseulles-sur-Mer (between 12km and 25km from the coast). The optional scope is: - Pile driving test(s) (only for monopile foundations type); - Design, manufacturing, delivery, transportation, installation, commissionning of an offshore met mast for the […]
It is often assumed that offshore wind farms have a negative impact on marine animal populations but researchers from Denmark and the Netherlands have found that, in some cases, wind farms can act as a haven for certain species. The researchers, from Wageningen University and Research in the Netherlands and Aarhus University in Denmark, monitored […]
