IMPROVE WHARF REFUELING CAPABILITY – U.S. NAVAL SUPPORT FACILITY, DIEGO GARCIA

P-1705 IMPROVE WHARF REFUELING CAPABILITY – U.S. NAVAL SUPPORT FACILITY, DIEGO GARCIA, BRITISH INDIAN OCEAN TERRITORY (B.I.O.T.)

PROJECT DESCRIPTION:

The U.S. Navy Support Facility (NSF) Diego Garcia is located in the Indian Ocean within the British Indian Ocean Territory (B.I.O.T.). NSF Diego Garcia is located south of equator approximately 2900 kilometers southwest of Bombay, India and approximately 2400 kilometers northeast of Mauritius, 4,723 km west-northwest of the west coast of Australia, and approximately 8,906 kilometers southwest of Guam.

Diego Garcia is a narrow coral atoll, is the largest of the 60 small islands comprising the Chagos Archipelago, being an atoll occupying approximately 174 square kilometers, of which 27.19 square kilometers is dry land. The coral atoll is horseshoe-shaped giving it the nickname “Footprint of Freedom” with an opening approximately 6.4 kilometers wide where the lagoon transitions into the Indian Ocean. The land distance from tip to tip of the atoll is 64 kilometers, enclosing a lagoon 21 kilometers long and up to 11 kilometers wide. The total land area is approximately 2720 hectares. Grade elevations on the atoll range between one to nine meters above Mean Sea Level (MSL) with an average elevation of 1.8 meters MSL.

Project Scope: The project called for the construction and completion of Improve Wharf Refueling Capability that would support to Military Command Vessels’ refueling needs berthed or moored at the Deep Draft Wharf (DDW) in Diego Garcia.  The work included constructing two (2) new fuel pits on the DDW (one for JP-5 and one for IFO-180), construct two (2) new pipelines from the DDW Fuel Pits to the existing main tank farm, construct new above ground tie-in manifold connecting the new pipelines to the existing fuel transfer lines, and construct a new Emergency Fuel Shutoff System for the DDW. Work also included repairs to the existing tank farm pump house by replacing the existing pumps, power service, pump controls, motor starters and instrumentation. New foundations were constructed and installation of pipe supports, valves, strainers and associated suction & discharge piping for the replaced pumps, and incidental work.

Several Notable features of work included:

• Construct Two (2) each – Fuel Pits-one each for JP-5 and IFO-180
• Construct (2) new pipelines from DDW Fuel Pits to main tank farm
• Construct new above ground tie-in manifold connecting the new pipelines to the existing fuel transfer lines. Total linear footage of new fuel pipelines from Tie-in Manifold to DDW Fuel Pits are 2,880 LF and 2,900 LF for JP-5 (16” dia.) and IFO-180 (12” dia.), respectively. While total volume capacity of the fuel piping system are 27,360 gallons and 17,052 gallons, respectively, complete with Cathodic Protection System.
• Construct Two (2) each – Valve Containment Pads
• Construct One (1) Each- Above ground Valve Manifold
• Construct One (1) each new Emergency Fuel Shutoff System for the DDW
• Construct One (1) each Roofed Hose Rack at DDW area
• Construct Six (6) each – Fuel Pump complete with power service, pump controls, motor starters and instrumentation.

Provide new foundations, pipe supports, valves, strainers and associated suction and discharge piping for the replaced pumps, and incidental work.
