Three Core Businesses: SURF Shallow Water Production Facilities Drilling, Riser & Subsea Equipment Click to edit Master title style Current Practice • Individual pipe joints welded together to make a pipe string • Offshore welding, NDT and coating Offshore Pipeline Construction GMC concept -- Connector Lay • Mechanical connection of pipe sections • Established practice in drilling • Simpler, quicker and more effective process? Click to edit Master title style • Mechanical Connector • Pipe Joint Preparation • Installation Options Concept Overview Click to edit Master title style GMC Mechanical Connector A pin and box type mechanical (integral coupled) connector Key Features: • Concentrically grooved connector • Multiple metal to metal nib seals • ID and OD preloaded contact shoulder • Highly fatigue resistant (>DNV-C1) • Excellent torsional slip resistance • Fast make-break cycles • Wide range of sizes (6" to 48") Click to edit Master title style Mechanical Connection Click to edit Master title style Mechanical Connection Click to edit Master title style Mechanical Connection V Welding Click to edit Master title style ISO21329 -- Testing & Qualification • An international standard that specifies a series of tests that provide a physical demonstration of the integrity of a pipeline connector • The tests provide objective evidence that the connector performs to a defined performance envelope • Types of testing included: o Make, break and torque tests o Service load tests o Limit load tests o Fatigue Tests Test program agreed with and witnessed by DNV Click to edit Master title style Make-Break & Torque Testing Make-Break Testing • Five sets of make and breaks per connector set • A total of more than 40 make/break operations where performed with no galling or tooth damage Make and Break Stab-in Torque Testing Pin & Box Connectors after multiple breakout Test Torque = 1582 ft. kips Click to edit Master title style Installation & Hydrostatic Load Testing Installation Test: Bending - with and without external pressure (2,916 psi) Hydrostatic testing: Internal pressure (3,375psi) with bending (1,328 ft. kips) Click to edit Master title style Operational Load Testing Operational Unrestrained Loads • 20 Load Cycles (bending + axial tension) • Temperature Cycles • Pressure Cycle (5 cycles) Operational Restrained Loads • 20 Load Cycles (axial compressive) • Temperature Cycle • Pressure Cycle (5 cycles) Click to edit Master title style Limit Load Testing Internal Pressure to Failure -- pipe burst at 8,487 psi Axial Tension to Failure - Pipe failure at 4,337 kips &1,934 psi (IP) Bending to Failure - Peak Bending Load of 2,200 ft. kips Click to edit Master title style Fatigue Cycle Testing E C - All connectors met and exceeded DNV "C" curve - Fatigue life 10X better than field welded pipe (DNV E) • Six sets of connectors tested at low, medium and high stress range (two at each) • Connectors #2 and #3 tested at 2,250 Psi internal pressure Click to edit Master title style ISO21329 Qualification Certification DNV "Statement of Conformity" document number HOU-01-SC-42039783. Key Milestone: (January 2010) Probably the first mechanical connector to conform to ISO 21329:2004 Click to edit Master title style Connector Summary • Superior to welded connection: o Stronger o Better fatigue life o Rapid connection o Consistent quality of connection o Reusable -- make / break • Available in a range of sizes • Suitable for dynamic applications • DNV approval to ISO21329 • Patent protection Click to edit Master title style Experience Where It Counts, Innovation Where It Matters.
