API 650 Storage Tank Engineering Services
Detailed engineering and design documentation for API 650 above-ground storage tanks — serving oil & gas, refinery, and petrochemical facilities across Saudi Arabia.
SLETEC Engineering provides API 650 storage tank engineering services for all tank types across Saudi Arabia — fixed roof tanks (cone roof, dome roof, umbrella roof), open-top tanks, internal floating roof tanks (IFRT) and external floating roof tanks (EFRT). We cover welded, field-erected and shop-fabricated tanks in all fluid services: crude oil, fuel oil, diesel, condensate, slop oil, water (potable, raw, fire water), chemical, caustic, acid, lube oil, hydraulic oil and process fluids. Our tank engineering scope covers shell course design, roof design, annular plate and bottom plate layout, nozzle reinforcement, wind and seismic load analysis per API 650 Appendix E, and complete tank fabrication drawing packages.
For tank repair and modification, SLETEC produces API 653 engineering documentation — shell remaining life calculations, minimum allowable thickness analysis, tank settlement check, tank repair drawing and tank repair method statement. We also prepare tank venting calculations per API 2000, nozzle reinforcement for tank modifications, and tank as-built drawing updates. Tank farm piping layout, tank foundation drawing and anchor bolt design are available as coordinated deliverables.
SLETEC's tank engineering deliverables are coordinated with the piping, structural and civil disciplines and formatted to Saudi Aramco, SABIC and client project specifications. Our tank GA drawing, shell plate layout, roof structural drawing, nozzle schedule, staircase/handrail drawing and wind girder detail are all produced in AutoCAD to IFC standard with full revision control. Tank FEA analysis is available for nozzle local stress, settlement and special load verification.
Engineering documentation prepared with reference to API, ASME, AISC, AWS, ISO, Saudi Aramco, SABIC and client project specifications where applicable.
