Ambient Site Built Storage Tanks


Rhyal Engineering offer design, fabrication and construction services for all ambient site built storage tank and vessel types:

  • Fixed cone roof tanks
  • Steel and geodesic dome roof tanks
  • External floating roof tanks
  • Open top tanks
  • Steel Liners
  • Pressure vessels and spheres
  • Personnel and equipment to site erect and weld client supplied materials

Our tanks are typically designed to either EN14015 or API 650. Whilst these design codes are primarily used in the petroleum industry they can be adapted and utilized for tanks used to store non-volatile or inflammable liquids. We are also experienced in working to alternative industry codes as required.

Manufacturing process

We can supply tanks manufactured from a variety of steel materials such as carbon steel, nickel or stainless steels. With tanks sizes ranging upto 100,000 cubic metres.

We manufacture the majority of tank components in our extensive workshops in Milford Haven such as:

  • Annular plates & floor sump subassemblies
  • Roof structures
  • Nozzles and access manways
  • Staircases, ladders and platforms

Other components are manufactured by our specialist supply chain. All components are delivered to site for construction by our own teams of highly skilled personnel.
