1. API 17 – Subsea Boosting Discussion Recommended Practice for Integrity Management, Qualification Requirements, and Referenced Standards Purpose of discussion: 1.Seek common ground and new insight into issues related to recommended practices for qualification and integrity of subsea boosting equipment 2.Gauge interest in establishing a focused industry group in API committee 17 to address this topic Talking Points: – An industry standard RP on subsea boosting should help gain project approvals from regulatory agencies – Need standard approach to defining risk and required risk mitigation – Hopefully avoid potential barriers to SS boosting project approvals – Can we continue to rely on “due diligence”, or should we have an agreed recommended practice? – What does “qualified” mean for SS Processing? Requirements to gain regulatory agency approval? To ensure safety and integrity? Where/how to qualify? – Should qualification philosophy be “Test to Success” or “Test to Failure”? Standard guidelines for qualification testing? – Qualification: should there be STD simulated fluids, viscosity, temp, gvf and STD output format – Could we use existing SS standards (API 17N,P,O,Q,D, ISO 13628)? – or is a new one needed to clarify? – Could other industry standards be utilized? DNV RP A203? Or ?? – Do (or should?) standards define a “qualified “ system or just a systematic framework for doing things? – How have Operators adapted qualification processes to project requirements and timelines?

2. ItemAreaComments 1Scope - Pumps - Motors - Instrumentation and Controls - Barrier fluid systems - Pump mounted electrical equipment (penetrators) Does scope need to be more limited or should it be exapnded beyond these items? 2Design RequirementsShould standard design ratings be adopted in a similar manner to other API equipment areas. i.e. 5,000 psi, 10,000 psi…… 0 to 250 F etc or should there be freedom to provide intermediate application specific ratings? Should there be standard ratings for motors? Is this practical? 2.1Pump AssemblyInvoke API 610? 2.2Pump CasingsWhat design codes should be used. Applying ASME VIII D2 leads to more conservative designs than well control equipment (i.e. 2/3 Sy versus ~0.55 Sy @ 250F) 2.3Motor CasingsSee comment for item 2.2. 2.4Pump mechanical sealsInvoke API 682? 2.5Barrier Fluid SystemsInvoke API 682? 2.6Pump rotors / rotodynamicsDesign and analyse per API 610. Monitor vibration during FAT per API 670? 2.7Pump MotorsInvoke API 546 or API 547? Should motor types be discussed? 2.8PipingApply ASME B31.8 like other subsea packages or is another code more applicable? ASME B31.8 will yield less conservative designs than ASME VIII D2 2.9Flanges / ConnectionsWhere practical use API flanges. Where not design and qualify OEM connection in accordance with API 17D 2.10 FastenersIn accordance with API 17D?
