DEME Offshore US will utilise Seaqualize’s offshore lifting device – the Heave Chief 1100 (HC1100) – for work on the Vineyard Wind offshore wind farm in the USA.
DEME Offshore will transport and install 62 wind turbine generators for the Vineyard Wind 1 project, the first commercial-scale offshore wind installation in the USA. Each turbine will be transported in components from the supply harbour to DEME’s installation vessel Sea Installer. DEME Offshore US has contracted the HC1100 to ensure the components can be safely lifted from the heaving supply barges. It can handle loads up to 1,100 tonnes.
“We contracted Seaqualize to de-risk the Vineyard Wind project: the solution is a novel, but realistic method to safely transfer the delicate components, minimising the risk of damage and delays. We think this is how feeder barge operations should be done going forward,” said Glenn Carton, project director Vineyard Wind at DEME.
The HC1100 is based on a 600-tonne capacity prototype developed with Van Oord’s offshore wind energy division, and was tested in November 2021. It is scheduled for delivery in March 2023.DEME Offshore US will utilise Seaqualize’s offshore lifting device – the Heave Chief 1100 (HC1100) – for work on the Vineyard Wind offshore wind farm in the USA.
