Aviation Fuel System Leak Detection at JFK Intl Airport, NY Charlie Fenton - HCNA
Why 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-90/010 Leak Detection System Technology Requirements 3 rd Party Evaluated Listing on NWGLDE MDLR of.0038% line normal operating pressure with a P D of 95% and P FA of 5%
JFK Airport Fuel System-Overview Bulk Fuel Farm 62 Tanks w/ associated pipeline Transfer Lines 6 Lines transfer all fuel from Bulk to Satellite Fuel Farms North Transmission Lines 10 Lines to Terminals 6, 7, 8 South Transmission Lines 16 Lines to Terminals 1, 2, 3, 4, 5 Terminal Hydrant Lines 8 Systems with unique isolation, surge suppression, fueling schedules Satellite Fuel Farm 40 Tanks w/ associated pipeline
Project Project conducted in phases 1.Six Fuel Farm Transfer Lines 2.Eight Terminal Hydrant Systems All individually contracted 3.27 Transmission Lines 4.Bulk and Satellite Fuel Farm Tank Lines Common to all projects Testing scheduled with fuel operator Operations would need to continue Isolation required for every line tested
HCNA Leak Detection System-Concept Dual Pressure Step Method Test section must be fully isolated for duration of test No fuel movement during test Connect Trailer to Test Section 45 minute test duration Capable of detecting a leak of gal/hr or 0.002% of line volume at a P D >95% and P FA <5% at reference pressure of 145psi Leak Simulation confirms Test Result
Project Phase 1: Bulk to Satellite Transfer Lines - Lifeline of JFK Proving the concept: Will testing at JFK work??? September 28-29, 2009: All parties involved Testing Successful! Concept Proven!!
Project Phase 2: Terminal Hydrant Pipeline Contracted individually for each terminal Unique testing conditions, scheduling, and configurations for each terminal To accommodate fueling operations, testing was performed during the day and night Strict 4 hour hydrant shutdown windows Escort required at all times
JFK Hydrant Line Testing Example: Terminal 4 Terminal 4 9 hydrant lines 5 separate test sections 2 concourses + hardstand Isolation of fuel lines Four isolation pits 16 surge suppressor pits Test connections HPVs and/or LPDs Jumper hoses Day/night scheduling Vault access
Project Phase 3: Transmission Lines 26 lines transmit fuel from Satellite Fuel Farm to each terminals hydrant lines 3 or 4 transmission lines dedicated to each of the 8 terminals HCNA test connections made at Satellite Fuel Farm Coordinated with each terminal which lines would be shutdown for testing PA assisted HCNA in isolation procedures Performed at each isolation vault adjacent to terminals When possible, multiple sections tested simultaneously
JFK Transmission Lines Example: Terminal 1 3 Transmission Lines At least one line allocated for fueling operations during testing Isolation vault accessed in busy fueling apron PA assistance No contractor needed for isolation requirements
Project Phase 4: Fuel Farms Bulk Fuel FarmSatellite Fuel Farm 72 pipeline test sections No impact to fueling operations Using chemical marker technology, operations continued despite testing Testing completed in 7 weeks 127 pipeline test sections Consolidated into 73 after testing was complete Using HCNA LDS, operations continued despite testing timing and fuel rerouting Testing completed in 12 weeks (51 days of testing)
Bulk Fuel Farm Test Section Fill F/S 7,8 Constant operational use Immediately downstream of Buckeye Partners, L.P. operations Inactive headers Excessive air Above and below ground pipe segments Trapped air Valves Check valves Poor isolating butterfly valves (BFV) at filter station Poor isolating double block and bleed valves on Buckeye manifold Non-functioning plug valves No test connection points
Bulk Fuel Farm Test Section Fill F/S 7,8 Problem Constant operational use Check valves Poor isolation of butterfly valves Poor isolation on Buckeye manifold Non-functioning plug valves Trapped air in high point areas High traffic area by testing rig Lack of connection points HCNA Solution Non-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
Conclusion Tightness Testing the most complex, largest Airport fuel system in U.S. 20,500,000 gallons of total fuel storage at any time 2,078,000 gallons of line fill ~3,500,000 gallons of daily throughput Replenishing pipeline about 2x per day Successfully performed all leak detection activities without any impact on Airport Operations Right plan, right partners Successfully tested and complied with State Requirements We did itSo can you!
