Galglass supply large fire water tank to North Africa
Galglass Limited (the UK specialist in sectional bolted fire
water storage tanks) have recently completed a 2500m3 Fusion
Bonded Epoxy Coated Steel Fire Water Storage Tank in North Africa
for a world renowned power and gas producer.
The Fire Water Tank, which is 17.16m diameter x 12.06m high, was
installed using the Galglass jacking system to allow all work to be
carried out at ground level providing the safest possible working
environment.
This method of construction allows for the top ring of the tank
and the roof to be completed first and for the access steelwork
and flanges to be fitted at ground level before the tank is elevated
each time by 1.5m and the next ring of panels added without the site
crew having to work at height.
The supply from Galglass comprised a free-spanning sectional steel
roof (without any internal columns), pipe-work for the inlet and
outlet of water, steel access ladders with rest platforms and inspection
platforms and a sectional steel floor for the base of the tank.
The roof, shell and floor were all supplied in Galglass’s premium Fusion
Bonded Epoxy Coating; which is a factory applied dry powder coating
process utilising a DuPont brand epoxy. Once applied, all coated surfaces
in contact with the stored liquid are subject to a 1000v holiday test to
ensure there are no manufacturing defects in the coating. All panels are
tested and any panels failing are rejected. The minimum design life of this
tank is 20 years and the actual operational life is far greater.
In accordance with the clients requirements, the tank shell and
roof were red in colour, but could have been green, blue, white
or desert sand too. Other colours are also available and all
colours within the RAL range are available with Galglass’s
flexible approach to business.
As a worldwide contractor as well as a manufacturing company,
Galglass were also responsible for the supervision of the installation
of the tanks and incorporated UK health and safety rules in line with
their safety manual which is accredited to 4 stars by the British Safety
Council in their 5 star rating system (the only tank company to have
such a high rating). This practice ensured the safe and practical
completion of the tank within the tight deadline stipulated.
Separate to the supply and installation, Galglass also provided a fully
detailed design package to incorporate all of the environmental and process
design requirements. These included designing all items to incorporate
seismic zone 3 earthquake loads (as per UBC & AWWA D103-97) and 160km/hr
wind speeds.
Galglass also managed the shipping of the project taking into account
the specialist documentation requirements for this type of high profile
project; including all of the quality and testing certification from the
production of the tanks, the specialist packing and containerisation
documentation and the post-production and shipping certification.
In addition to their Fusion Bonded Epoxy tank range, Galglass are also
manufacturers of Glass-Fused-to-Steel tanks, Galvanised Mild Steel tanks
(with and without liners) and aluminium and stainless steel panel tanks
(all of which are approved to LPCB and FM). With a wide product range and
