1Aviation Fuel System Leak Detection at JFK Intl Airport, NY Charlie Fenton - HCNA
2Why Test? New York State DEC 10 year MOSF pipeline testing requirement Section 6NYCRR, Part “Handling and Storage of Petroleum”Standard Test Procedures for Evaluating Leak Detection Methods: Pipeline Leak Detection Systems, EPSA/530/UST-90/010Leak Detection System Technology Requirements3rd Party EvaluatedListing on NWGLDEMDLR of .0038% line normal operating pressure with a PD of 95% and PFA of 5%
3JFK Airport Fuel System-Overview North Transmission Lines10 Lines to Terminals 6, 7, 8Bulk Fuel Farm62 Tanks w/ associated pipelineTerminal Hydrant Lines8 Systems with unique isolation, surge suppression, fueling schedulesTransfer Lines6 Lines transfer all fuel fromBulk to Satellite Fuel FarmsSatellite Fuel Farm40 Tanks w/ associated pipelineSouth Transmission Lines16 Lines to Terminals 1, 2, 3, 4, 5
4Project Project conducted in phases Common to all projects Six Fuel Farm Transfer LinesEight Terminal Hydrant SystemsAll individually contracted27 Transmission LinesBulk and Satellite Fuel Farm Tank LinesCommon to all projectsTesting scheduled with fuel operatorOperations would need to continueIsolation required for every line tested
5HCNA Leak Detection System-Concept Dual Pressure Step MethodTest section must be fullyisolated for duration of testNo fuel movement during testConnect Trailer to Test Section45 minute test durationCapable of detecting a leak of gal/hr or 0.002% of line volume at a PD>95% and PFA<5% at reference pressure of 145psiLeak Simulation confirms Test Result
6Project Phase 1: Bulk to Satellite Transfer Lines - “Lifeline of JFK” Proving the concept: Will testing at JFK work???September 28-29, 2009: All parties involvedTesting Successful! Concept Proven!!
7Project Phase 2: Terminal Hydrant Pipeline Contracted individually for each terminalUnique testing conditions, scheduling, and configurations for each terminalTo accommodate fueling operations, testing was performed during the day and nightStrict 4 hour hydrant shutdown windowsEscort required at all times
8JFK Hydrant Line Testing Example: Terminal 4 9 hydrant lines5 separate test sections2 concourses + hardstandIsolation of fuel linesFour isolation pits16 surge suppressor pitsTest connectionsHPVs and/or LPDsJumper hosesDay/night schedulingVault access
9Project Phase 3: Transmission Lines 26 lines transmit fuel from Satellite Fuel Farm to each terminal’s hydrant lines3 or 4 transmission lines dedicated to each of the 8 terminalsHCNA test connections made at Satellite Fuel FarmCoordinated with each terminal which lines would be shutdown for testingPA assisted HCNA in isolation proceduresPerformed at each isolation vault adjacent to terminalsWhen possible, multiple sections tested simultaneously
10JFK Transmission Lines Example: Terminal 1 At least one line allocated for fueling operations during testingIsolation vault accessed in busy fueling apronPA assistanceNo contractor needed for isolation requirements
11Project Phase 4: Fuel Farms Bulk Fuel FarmSatellite Fuel Farm127 pipeline test sectionsConsolidated into 73 after testing was completeUsing HCNA LDS, operations continued despite testingtiming and fuel reroutingTesting completed in 12 weeks (51 days of testing)72 pipeline test sectionsNo impact to fueling operationsUsing chemical marker technology, operations continued despite testingTesting completed in 7 weeks
12Bulk Fuel Farm Test Section “Fill F/S 7,8” Constant operational useImmediately downstream of Buckeye Partners, L.P. operationsInactive headersExcessive airAbove and below ground pipe segmentsTrapped airValvesCheck valvesPoor isolating butterfly valves (BFV) at filter stationPoor isolating double block and bleed valves on Buckeye manifoldNon-functioning plug valvesNo test connection points
13Bulk Fuel Farm Test Section “Fill F/S 7,8” ProblemHCNA SolutionConstant operational useCheck valvesPoor isolation of butterfly valvesPoor isolation on Buckeye manifoldNon-functioning plug valvesTrapped air in high point areasHigh traffic area by testing rigLack of connection pointsNon-utilized bypass line Jumper hose Back-up with additional in-line valves Buckeye repaired overdue valve bodies Added in separate section Flushed line into vactruck Restricted fuel truck access Utilized thermal wells
16ConclusionTightness Testing the most complex, largest Airport fuel system in U.S.20,500,000 gallons of total fuel storage at any time2,078,000 gallons of line fill~3,500,000 gallons of daily throughputReplenishing pipeline about 2x per daySuccessfully performed all leak detection activities without any impact on Airport OperationsRight plan, right partnersSuccessfully tested and complied with State RequirementsWe did it So can you!
