5 Topics for High pressure Manifolds & Well Control Manifold Design Priority list Rules, Directives and Standards The STEP Offshore Manifold Design Control system Instrumentation Slide 5

6 Manifold Design Priority List Customer specification Rules, Directives and standards Certifying body DNV ABS Functionality Process capability Operability Maintainability Cost and Weight Slide 6

7 Rules, Directives and Standards National- and International Rules Machinery- and ATEX Directive ABS / DNV Standards API Standards and recommendations API-6A, API-16C, API-16D and API-RP53 NORSOK Standards D-001, D-002 and S-002 Slide 7

8 National Rules Challenges Machinery Directive does not comprise High Pressure Manifolds. C&K manifold is regarded as part of the equipment upstream the Christmas Tree and therefore excluded from PED CE-Marking referring to API is accepted by Norwegian authorities and DNV Slide 8

9 API Challenges Outdated instrumentation Hydraulic Pressure instrumentation De-boosters Accuracy Difficult to interpret and find information Bleed line bypassing the Chokes Different C&K Manifold configuration for surfaceand sub-sea BOP Overruled by ABS / DNV ABS and DNV certifies manifold without highlighting or taking deviation from ABS. Slide 9

10 NORSOK Challenges NORSOK I-001 Block and Bleed for Instruments Dual isolation for on line repair Pressure and Pipe Speck breaks conflicts Piping downstream the last High Pressure valve regarded as normally not containing pressure. Different pressure rating on Mud Standpipe Manifold, Cement Standpipe Manifold and C&K Manifold Slide 10
