A UK (Scotland) SME is active in the field of operations and maintenance of wind farms carrying out gearbox and hydraulic oil exchanges on operational onshore and offshore wind turbines.
During the oil exchanges 45 degC 320ct gear oil is extracted from the wind turbine gearbox situated in the wind turbine nacelle via the company's own developed pumping equipment and is pumped from the nacelle to ground level via 3/4" 2SN hydraulic hose (up to 150 meter). In colder ambient temperatures this gear oil will cool down in the hose to a point where it is no longer possible to pump the oil as it has become to viscous within the hose and the pumps are then unable to pump the oil.
Therefore the company are looking for a flexible and rugged heat retention material for their hydraulic hoses that enables them to retain the oil temperature within the hose itself.
The company is looking to collaborate via a technology cooperation agreement.
