Aviation Fuel System Leak Detectionat JFK Intl Airport, NY Charlie Fenton - HCNA
Why Test? • New York State DEC 10 year MOSF pipeline testing requirement • Section 6NYCRR, Part 613.6 “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 • 3rd Party Evaluated • Listing on NWGLDE • MDLR of .0038% line volume @ normal operating pressure with a PD of 95% and PFA of 5%
JFK Airport Fuel System-Overview North Transmission Lines 10 Lines to Terminals 6, 7, 8 Bulk Fuel Farm 62 Tanks w/ associated pipeline Terminal Hydrant Lines 8 Systems with unique isolation, surge suppression, fueling schedules Transfer Lines 6 Lines transfer all fuel from Bulk to Satellite Fuel Farms Satellite Fuel Farm 40 Tanks w/ associated pipeline South Transmission Lines 16 Lines to Terminals 1, 2, 3, 4, 5
Project • Project conducted in phases • Six Fuel Farm Transfer Lines • Eight Terminal Hydrant Systems • All individually contracted • 27 Transmission Lines • 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 0.068 gal/hr or 0.002% of line volume at a PD>95% and PFA<5% at reference pressure of 145psi • Leak Simulation confirms Test Result
Project Phase 1: Bulk to Satellite Transfer Lines - “Lifeline of JFK” Testing Successful! Concept Proven!! • Proving the concept: Will testing at JFK work??? September 28-29, 2009: All parties involved
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 terminal’s 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 LinesExample: 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
Bulk Fuel Farm Satellite Fuel Farm Project Phase 4: Fuel Farms • 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) • 72 pipeline test sections • No impact to fueling operations • Using chemical marker technology, operations continued despite testing • Testing completed in 7 weeks
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 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 • 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
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 it So can you!
