Mounted on a 3m concrete plinth, this 4,000 cubic metre BioSphere gasholder was recently installed by our installation crew at Knostrop Sludge Treatment Facility in Leeds for Yorkshire Water Services Ltd. With a base diameter of nealy 18m and a height of around 15.5m, this BioSphere is an imposing structure that requires expert installation techniques and takes around six hours to inflate once secured to the plinth. All production was performed in-house by AJ Tensile Manufacturing Ltd at our facility in Caldicot, with design, project management and installation performed by AJ Tensile Biogas Systems Ltd. Additional volumetric checks were performed on-site after inflation to confirm the accuracy of the level-checking laser by measuring discharged air using an anemometer.
AJ Tensile Biogas Systems Ltd recently completed a 2,500 cubic metre Biosphere for export to Pontiac, Michigan in the USA. Constructed using our double-skin membrane design and with an operating pressure of 20 millibar, this tank-mounted gasholder will stand around 10.5m high when fully inflated and was fabricated in-house by our production division, AJ Tensile Manufacturing Ltd.
The Special Projects division of A J Tensile Manufacturing Ltd recently completed a prestigious staging installation for one of our major clients. Consisting of two 60m arched trusses with an octagonal suspended roof over a raised stage, the structure was one of seven temporary staging installations for the All Points East Festival in Victoria Park, East London. Our fabric panels provided cover and backdrop for the lighting arrays built into the arches.
We had to work to a very tight schedule but our client was very pleased with the final result, saying “A J Tensile did it again, managing to deliver as always, despite the late information”.
This slab-mounted 400 cubic metre BioSphere gasholder was designed and project managed by our Biogas company and fabricated by our Manufacturing division for a client in Jakarta, Indonesia. This is the first BioSphere that we have produced for the Indonesian market and it had to be manufactured to a very tight program so that five weeks of port-to-port sea delivery could be achieved. Installation will be performed by the client under the direct supervision of one of our senior installers.
Our Biogas division recently completed one of the smallest gasholders we have ever produced for a client in Ontario, Canada. Measuring just 50 cubic metres and standing around 4m tall, the double-skinned slab-mount Biosphere was awarded to us by our North American licensee and manufactured in-house by our Manufacturing division before being carefully packed and crated for export.
Our Biogas and Manufacturing divisions collaborated recently to complete a 975 cubic metre Biosphere gasholder at Sandown on the Isle of Wight for Southern Water and Barhale Trant Utilities LLP. This was to replace an existing unit that had come to the end of its long and happy life, and our new design offered improvements by having no gap between the inner and outer membranes.
The installation went smoothly despite adverse weather conditions where the whole site was blanketed in thick snow, and our installation crew worked closely with the client to ensure that delays were kept to a minimum. The gasholder went into full operational service only a week after the installation was completed.
