Dampers control oil storage bunker doors in high winds
Industrial Gas Springs (IGS) has provided large size dampers to control a set of doors on a storage bunker at an oil refinery situated on the coast of West Wales. Aker Kvaerner Engineering Services approached the company in the course of carrying out work at the site, with a view to finding the most efficient solution to a potential safety hazard, looking for suitable gas spring/shock absorbers for two fully clad 2m wide by 4m high doors.
The doors needed to be able to take a wind load of 3kN when opening/closing but the dampers were not required to assist in opening/closing operations or in restraining the leaves in their open/closed positions.
The solution was to use five-off dampers with a size 20mm rod and 40mm body diameter for each door, fully oil damped in compression and free in extension. The dampers have proved a very effective solution.
