NGL Storage Facility Expansion

NGL Storage Facility | Audubon Companies | Integrated EPC Services

Client:

A major oil & gas manufacturing and logistics company

Location:

Brazoria County, Texas

Project summary:

Audubon supported the natural gas liquid (NGL) storage demand via a contract for a brownfield expansion of an NGL storage facility in Brazoria County, Texas.

The five cavern greenfield design and construction support for phase I was completed in 2014. Phase II included process design and engineering for the facility’s topsides, total installed cost (TIC) estimating, piping and instrumentation diagrams (P&ID), and process hazard analysis (PHA )and layers of protection analysis (LOPA) reviews.

Additional services included performing a front-end engineering design (FEED) study to determine the scope of work and EPC schedule and risk register.

The project schedule for the 6 MMbbl NGL storage project was accelerated and completed within 18 months.
