Storage tank
We are experienced in designing Atmospheric, Pressurized, or Low Pressure Storage tanks for Oil and/or LPG depots. Designs are guaranteed to comply with International Standard API 650/BS 2654 (Welded Tanks for Oil Storage) or API 620 (Design and Construction 
of large, welded, low pressure storage tanks).

We are capable of designing a variety of Cylindrical Storage tanks with different capacities and shell diameters up to 60 meters. Tank roof designs include: External Floating roof, Self-supported Cone roof, Supported Cone roof, Dome roof, with optional Internal Floating roof. 

We are also capable and experienced with designing Spherical Storage tanks with diameters between 12 and 24 meters for Liquefied Gases such as LPG, Propylene, Ammonia, etc. Our Spherical Storage tanks are U or U2 certified, satisfying the requirements from ASME Sect. VIII Div. 1 or Div. 2.


We utilize state-of-the-art software such as TANK, PVElite, STAAD Pro, in analyzing and designing of tank's shell, manhole, structures, etc. Continuing development from the Front End Engineering Design (FEED) documentation such as equipment specification and datasheet, we can develop additional detail design documentation such as:

  • Shell thickness/Nozzle stress calculation,   

  • Structural stress analysis, 

  • Detail design/Fabrication drawing package, 

  • Detail MTO (including shape steel, steel plate, pipe fittings, bolts & nuts, paiting area) 

  • Inspection, Testing & Construction Procedures/Specifications (Hydrotest, ITP, Painting, Steel Materials..)
