Philadelphia Gas Works LNG Storage

PROJECT HIGHLIGHTS 

  • This PRELOAD LNG project for Philadelphia Gas Works presented a unique challenge due to the soil conditions at the building site: 
    • Each of the two 230’ ID x 82’ SWD tanks were supported by over 2,200 piles, and high molecular weight plastic pipes were used over typical metallic conduits due to the corrosive nature of the soil. 
    • Load bearing insulation was used for the wall footing as well as the floor to additionally protect from temperature and differential stresses. 
    • Like many LNG projects, the outer prestressed concrete walls were used as a dike system. 
  • PRELOAD also accounted for several other potential hazards in the design, such as the ability to support the weight of fire protection and vaporization equipment. 
  • These tanks are another example of how PRELOAD stands ready to accept any LNG storage challenge with a tank system to suit the operation’s specific needs.
