According to Seaqualize, the battery-powered HC1100 is at the moment the most important energetic heave compensator on the earth.
DEME Offshore US LLC is to make use of a brand new heave-compensated offshore lifting answer on its contract to put in the wind generators for the primary large-scale offshore wind set up within the U.S., Vineyard Wind 1.
As we reported earlier, DEME will set up the generators utilizing a foreign-flag wind turbine set up vessel (WTIV) serviced by Jones Act compliant Foss Maritime feeder vessels. To safely switch the wind turbine elements from the heaving feeder vessels, DEME has awarded Dutch movement compensation specialist Seaqualize the primary contract for its newly developed offshore lifting system: the Heave Chief 1100. According to Seaqualize, the battery-powered HC1100 is at the moment the most important energetic heave compensator on the earth. As a balanced heave compensator (BHC), it could possibly compensate a vessel’s heave motions and safely quick-lift masses as much as 1,100 tonnes.
The Vineyard Wind 1 challenge will see DEME transporting and putting in 62 wind turbine turbines on the wind farm website off the coast of Martha’s Vineyard, Mass. Each turbine shall be transported in elements from the provision harbor to DEME’s set up vessel Sea Installer utilizing Foss Maritime provide barges.
“We contracted Seaqualize to de-risk the Vineyard Wind project: their solution is a novel, but realistic method to safely transfer the delicate components, minimizing the risk of damage and delays,” mentioned Glenn Carton, challenge director Vineyard Wind at DEME. “We think this is how feeder barge operations should be done going forward.”
HEAVE CHIEF 1100
Seaqualize has been growing inline balanced heave compensators, particularly for heavy elevate, in-air energetic load management since 2019. Together with Van Oord Offshore Wind, it efficiently examined a 600 tonne capability prototype in November 2021. The HC1100 relies on this prototype and would be the world’s largest and most refined energetic heave compensator.
Set for supply in March 2023, the HC1100 has a load-capacity of 1,100 tonnes, required to stability turbine elements of the 15 MW technology. It can attain greater quick-lift speeds than the prototype and has an extended stroke to deal with the bigger motions of smaller provide vessels. It additionally presents a single elevate level for operational effectivity. The new design additional minimizes dynamic load fluctuations impacting the crane and presents passive security procedures. In addition, Seaqualize’s in-house developed “follow-mode” permits the complete load to match the actions of the goal vessel. If required, quick-lift operations are absolutely reversible.
Seaqualize says that a lot of offshore set up contractors are at the moment investigating embrace the Heave Chief into their feeder-barge setups and that it expects to announce an extra contract earlier than the top of the 12 months, . Alongside the HC1100, the corporate’s first full-scale BHC prototype is at the moment being upgraded for working masses as much as 750 tonnes
