INTEG 'Twinskin' tanks for Dublin

Integ Twinskins for Dublin

Installation of three 'Twinskin' tanks for a chemical company in Dublin.

A 300m3 tank (7.5M i/d x 8.5M shell) was constructed on site with double integrity base and shell for additional environmental protection.

The tanks next to the site constructed large tank were two 75m3 tanks (3M i/d x 14.7M overall) and were fabricated in England and shipped to site in one piece for offloading & positioning. These tanks were of similar 'Twinskin' construction but also had the unique feature of a 45 degree sloping inner bottoms for total drainage.

INTEG Solve a Problem for Texaco

PROBLEM - The Texaco aviation fuel depot at East Midlands Airport required additional storage capacity in the form of 400m3 site erected tank 8M x 6M high. As an operational fuel storage facility 'hot work' could not be permitted within the tank compound.


INTEG fabricated and test the tank on a temporary pad outside the perimeter fence and the lifted the completed tank over the fence into the compound (pictured). The tank was retested, internally lined and externally painted in it's final location.

The Tanks That Came Back

The Tanks That Came Back

During 1996 INTEG supplied a number of stainless steel tanks to our Client's tank farm. In 2005 the tank farm was de-commissioned and the tanks were put up for sale.

  • Following suitability and economic viability consultation with INTEG, Our new Client purchased two of the tanks for a new project at Newcastle.
  • INTEG carried out design calculations to re-classify the tanks for a higher S.G. product, various nozzle changes and designed a special side entry mixer nozzle taking loadings into account. A new set of CAD drawings were prepared to detail these changes.
  • The tanks were returned to our works and the modifications were carried out in 2 weeks. Following hydraulic testing and certification, delivery was arranged so that they could start their new life in Newcastle.
  • The end result was that the client saved both money and lead-time compared to purchasing new tanks.

INTEG Help Airbus Fly

INTEG Help Airbus Fly

Working with the Airbus fuel systems engineers at Filton Bristol, Integ have over the last few years supplied specialised tanks, test chambers and rigs to assist the development of fuel systems for the A380 and other aircraft.

For altitude simulation, the mainly rectangular tanks require special design for full vacuum and sub zero temperatures of - 57 degrees centigrade. Integ have designed these tanks using in house stress analysis software verified by 3rd Party test and certification.

Some examples are shown above including a full A380 worth of fuel tanks assembled at Kemble Airfield for surge testing on refuelling. Integ also designed and supplied the bulk fuel tanks for this rig.

Do You Know the Condition of Your Tanks?

Do You Know the Condition of Your Tanks?

You may say "fine" but this is not necessarily good enough to satisfy your statutory obligations and insurance companies. Do you have in place a documented survey/inspection plan on an ongoing basis with condition reports on all tanks.

Integ can provide:-

Condition survey:- - A full condition report with ultra-sonic material thickness checks and any remedial recommendations.

  • Compliance survey:- - Will the installation comply with Control of Pollution (Oil Storage) (England) Regulations.
  • Purchase survey:- - If you are considering the purchase of a second-hand tank we can survey to assess condition and suitability for intended use.
  • Change of use survey:- - Survey & calculation check to reclassify the tank for use with higher S.G. products or at elevated temperatures.
