The Bolton Valley wind turbine will be erected next week, beginning Monday, when the structure is taken up the mountain in sections. This is the first wind turbine to be erected at a Vermont ski area and only the second at a ski area anywhere in the entire country. Equipment will be staged at Bolton Valley over the weekend, with the first sections of the turbine headed up the mountain Monday morning about 7am.The tower parts will arrive at Bolton Valley on two trucks and taken up the mountain, in stages, on an all terrain trailer pulled by a D8 bull dozer for the final approach to the peak. Once at the peak a massive crane will remove the first section of the tower from the trailer for placement on its foundation.Tuesday the second and third sections of the tower will be installed. The blades will be pitched on a pitching stand on the ground prior to being put in place Wednesday.For additional information or to make arrangements for getting to the peak to photograph or video the installation, contact Josh Arneson at Bolton Valley.Bolton Valley Wind Tower Construction ScheduleMonday, October 5The wind tower parts will arrive at Bolton Valley packed on two trucks. They will be transported up the access road and will need to be moved to an all terrain trailer pulled by a D8 bull dozer to make the final approach up the mountain to the peak. The process of switching trucks and beginning the final leg up the mountain will begin at 7:00am.Once at the peak the crane will remove the nested tower from the trailer and begin to un-nest all the wind turbine tower sections and stage them for assemblyLadder assembly will begin at the peakPlace the first section of the towerGrout the connection where the tower meets the foundationTuesday, October 6Place the second section of the towerPlace the third section of the towerPitch the blades which will be set up on a pitching stand on the groundWednesday, October 7Place the nacelle on top of the third tower sectionFinal piece will be lifting the blade assembly (rotor) into place. This will take place in the afternoon.
The system uses a pure electric drive system, making it more environmentally sustainable and also reducing the need for maintenance. “The new LARS benefits from a unique combination of our advanced subsea technologies, reinforced with years of accumulated offshore expertise.” Kongsberg ’s LARS is part of a system design to eliminate the need for people at sea while carrying out subsea operations. Also, another benefit is that launching and recovery can be carried out in higher sea states. This innovation enables the deployment of remotely operated vehicles (ROVs) and autonomous underwater vehicles (AUVs) by teams based onshore. Launch & recovery will happen through the moon pool, with the release and capture of the ROV occurring beneath the sea surface. This eliminates the possibility of damage to the ROV from impact with the vessel hull., Kongsberg explains. Lisa Edvardsen Haugan, executive vice president, Deck Machinery & Motion Control, Kongsberg Maritime, said: The contract comes from Ocean Infinity, who will install the system on its Armada fleet of robotic ships. Kongsberg Maritime has signed its first contract for an ROV launch & recovery system (LARS), specifically designed to handle remotely operated vehicles from unmanned vessels. “We believe this will be a game changer. The cost of ROV operations can be drastically decreased through use of this system. “We expect to see more companies transition to using unmanned vessels to reduce operational costs and increase safety.”
