Apex

500 & 1000 bbl Oil Storage Tank

Apex , Well Testing has developed its own set of fabrication specifications to ensure that equipment used by Apex Petroleum Services, Well Testing meets or exceeds all local requirements. Apex Petroleum Services, Well Testing specifications are primarily based on the following worldwide recognised specifications:

Equipment Design and Fabrication Specifications

  • API Spec 6A – Specification for Valves and Wellhead Equipment
  • ASME VIII For construction of pressure vessels , Div 1&2
  • API RP 14C – Recommended Practice for Analysis, Design, Installation, and Testing of Basic Surface Safety Systems on Offshore Production Platforms
  • NACE MR-01-75
  • Product Specification Level (PSL) 3
  • Material Class DD
  • Temperature Class P&X (-20° F to +350° F)

500 & 1000 bbl Oil Storage Tank

The tank is designed to allow easy access for multiple valves forming the inlet and outlet manifold. This optimizes use of the tank for clean-up operations or to store liquids.

A flame arrestor is an integral feature of the tank and is located at the gas/vent outlet line at the top of the tank. An additional safety feature is the inclusion of vent hatches/manholes, created by forming a balanced man entry opening, which allows the cover to be lifted, thus venting to the atmosphere should pressure begin to build up in the vessel.

The tank is equipped with internal access by a permanently installed ladder and foldable top handrails to ensure operator safety. Tanks may also be equipped with steam coils to provide the necessary heat required to ensure fluid viscosity is retained during operations.

The high capacity of the tank is an additional benefit for operations where well production can be transported to a loading facility, and the crude can be transferred for further processing.

Features and Benefits:

  • Allows safe crude transfer for additional processing
  • Foldable roof top handrail
  • External and Internal ladder
  • Detonation Flame arrestor
  • Thief Hatch
  • Liquid Level indication
  • Vacuum relief device to prevent overpressure
  • Earthing System
