Replace Fuel Piping & Tanks at Jet Fuel & Diesel Tank Farm - Point Loma, San Diego, CA

Pond provided full, comprehensive architecture and engineering services as well as construction phasing for this project. FISC Point Loma primarily received, stored and issued aviation turbine fuel and marine diesel fuel for redistribution to other Navy facilities. There were separate storage, piping and pumping systems for each fuel type. Altogether, the tank farm has a nominal shell capacity of 1,219,000 BBL. FISC Point Loma issues over 364,000 BBL of product monthly. Therefore, the purpose of this project was to replace an approximately 32,500 LF of existing underground fuel pipelines serving the two tank farms with new 16” diameter aboveground pipelines; replace 18 existing cut and cover tanks (nine jet and nine diesel = 597,000 BBL) with six new jet and six new diesel 50,000 BBL aboveground tanks; provide a new 7,100 GPM diesel pumphouse; and upgrade three existing aviation turbine fuel pumhouses (16,050 GPM total capacity).

Construction Phasing was a critical component of the project. There were several major operations which had to be coordinated in order for the tank farm to maintain operations and accomplish the construction.

The project was divided into the following major phases:

• Construct the aboveground pipelines outside of the tanks.
• Construct the underground casing pipes to tie into the cut and cover tanks.
• Drain, clean and gas-free each tank and tie in piping based on availability from the Navy and in accordance with the detailed construction phasing plan developed by Pond.
• Construct piping manifold outside of the main pumphouse, new substation and back-up generator for new pumps.
• Replace existing pumps, controls, piping and valves in main pumphouse while using auxiliary pumphouse to maintain operations.
• Replace existing piping from the pumphouse manifold to the pier supply and receipt line.
• Demolish one half of the existing jet fuel cut and cover tanks and fill in to use as a foundation for the new aboveground tanks, abandon existing underground piping.
• Construct new aboveground tanks, associated piping and containment.
• Repeat process for the remaining jet fuel tanks.
• Repeat the process for the cut and cover diesel tanks except the existing aboveground piping which will remain in place and be modified to connect to the new aboveground tanks.
