Maintain and Repair JP-8 Fuel System


Project Name: Maintain and Repair JP-8 Fuel System
Location: Shemya, Alaska
Contract Number: TMCC-04-C-0282
This Triton project completed in July of 2004 was difficult in nature due to its remote location at the far west end of the Aleutian Island Chain and was comprised of several modifications to an existing 12 inch fuel system. The modifications included removal of existing 12 inch valve assemblies and installation of new spools. Installation of new 10 inch pipelines. Disassembling, reconfiguring and installing new components in the facility pump house. Removal from service and closure of several pipelines. Decommissioning, removal from service, cleaning and closure of a 39,655 BBL Above Ground J-8 Fuel Tank. The work activities included alterations made to the existing fuel system where it was necessary to schedule system shut downs and drain downs to safely accomplish welded tie-ins of the new pipelines to the existing system. Installation of new 10” diameter pipelines. Installation and/or repairs to High Point Vents and Low Point Drains. Installation of Double Block & Bleed Valves, Control Valves, Pressure Safety Valves and Line Pressure Relief/Bypass Systems. The specifications required stringent pressure tests on over 1 mile of 10 inch fuel line. The remoteness of the project locale required that the correct components be ordered and delivered in one barge shipment. Temperamental weather, including high winds, cold temperatures, rain and snow were factors that had an effect on field activities including pipe welding and application of the three part paint system. These obstacles were taken into consideration during the planning stages of the project thus having little to no affect on the project field activities.
