Marathon Oil Company Petrobras KBR Engineering Mustang Engineering3Evolution of this edition It’s been 18 years since 14C was significantly revised.– The 6th edition was issued in 1998– The 7th edition was issued in 2003, but only 5 pages were changed– This was to incorporate Pressure & Level Transmitters and testing frequency Drivers for Change:– Items where BSEE has approved recurring deviations to API 14C, 30 CFR 250or NTL’s– Rupture disks and rupture pins in shell and tube exchanger service– Items not covered by the standards, (e.g., methanol systems, different types ofexchangers, low temperatures, etc.)– Items where users contend are not covered appropriately and lead toinconsistent regulation from BSEE– New items or systems driven by Deepwater, (Topsides HIPPS, PSV sizing, etc.).– Items driven by technology advancements42

4/5/2017Overview of Changes The API 14C – 7th Edition was about 100 pages The 8th edition is about 150 pages So there are lots of changes almost every page Some significant changes, but many are clerical or corrections ofmistakes All drawings & figures recreated in Auto-Cad API 14C Committee performed a complete word by word review toincorporate advancements in technology, cover operations in deepwater at higher pressures All subsea was removed and in coordination with the developmentof API 17V Recommended Practice for Analysis, Design,Installation, and Testing of Safety Systems for Subsea Applications Linkage to ISO 10418 broken5The “Biggies” SummarySignificant changes that you need to know New SAC References- mostly for highand low temps on vessels SAC tables configured for easy use Boarding Shut Down Valves (BSDV)requirements added Pipeline SDV/FSV must be testedannually and checked for leakage. Also must have a TSE Compressors- More SDV’s and VSH’s Logic Solver requirements added HIPPS Systems added SSV- leak rate is allowed. If sustainedliquid flow exceeds 400 cc/min or gasflow exceeds 15 ft3/min Pumps suction lines must have samepressure rating as discharge or PRDinstalled. Rotating Equipment Protection addedfor: Simple Overhung Centrifugal Pump Between the Bearings TypeCentrifugal Pump Seal System New SACs for FSL, VSH, TSE’s requirements modified BSDV and pipeline SDV Atmos. tanks - 1 per 5ft perimeter Pumps-Adjacent to pump seals/packing When a vessel goes thru severaldecks, each level should have equalcoverage.63

4/5/2017Other Changes to the 8th Edition? Overview of Changes–––––––––Expanded from Platforms to Facilities to cover floatersPneumatics vs. ElectronicsAPI STD 521 “Guide for Pressure-Relieving and Depressuring Systems”New requirements around large ( 1000HP) pumps & compressorsTopsides HIPPSBypassing RequirementsOpen Deck Fire and Gas DetectionConcept of Prevention vs MitigationMore complex safety system designs usersare directed to performance based standards– API 521 & IEC 61511 for HIPPS– API 670 for Large CompressorsSlide 7Sections / Annexes Appendix A remains & SAC Reference Do Not Change Appendix B in 7th edition was deleted Annex B- Examples of Safety Analysis Flow Diagram and SafetyAnalysis Function Evaluation (SAFE) Chart (Previously Appendix E) Annex C- Remote Operations (New) Annex D - Safety System Bypassing (New) Annex E- High Integrity Pressure Protection Systems (New) Annex F- Logic Solver (New) Annex G - Emergency Support Systems (New Fire & Gas Detail) Annex H –Toxic Gasses Annex I - Testing and Reporting Procedures Annexes defined as Informative or Normative (New)84

4/5/2017The Details9Pneumatics vs. Electronics “This recommended practice emphasizes pneumatic systems sincethey are the most commonly used ” – API RP 14C - 7th EditionSection 1.2– Pneumatics were prevalent when 14C was originated, but nowelectronics dominate, so the changes associated with the moveto electronics must be addressed. Logic Solver Requirements– Requirements shall be defined for logic solvers used on offshorefacilities.– Logic solvers shall be certified to IEC 61508or shall meet the requirements ofANSI/ISA 84.00.01-1 Clause 11.5.5.5– Other options are provided as alternatives tocertification5

4/5/2017Topsides Pressure Relief Systems Pressure Relief Devices (PRD) defined by type in 14C– PSV, PVRD, PRD, PSE Pressure Relief Sizing Scenarios- API RP 14C was revised to include additional references to API STD521 where applicable.- API STD 521 is not incorporated into 30 CFR 250, so BSEE will need toconsider incorporating it. Deepwater Subsea Flowline/Riser facility issue associated with linepacking; pressures and volumes can exceed those used to size theinlet separator relief system adding risk to the facility when openingof the boarding valve.– Relief Strategies Sizing relief valves for this scenario is often impractical Fixed restrictions can lower the pressure, but then can pose operationalissues during normal operations due to pressure loss. High Integrity Pressure Protection Systems (HIPPS) can be used inplace of additional relief valves for depressurizing events.Slide 11Topsides HIPPS HIPPS Requirements– 14C includes HIPPS requirements for topside and on flowlines wherePSV protection cannot be provided Limited HIPPS design for flowline remains as an option– HIPPS will be an independent system Performance option in accordance with API 521 (i.e. risk based SIL2/3solution)OR Prescriptive solution describing Design Commissioning Documentation Operation Maintenance & Testing126

4/5/2017Heat Exchangers Requirements for Heat Exchangers– Previous editions only address “shell & tube” exchangers, so plate &frame, pipe-in-pipe, etc. were added.– Review relief valve requirements to provide options for rupture discs /rupture pin and other forms of fast response relief devices due to issueof tube failure in high pressure gas exchangers.Slide 13Rotating Equipment Rotating Equipment Protection added for:– Simple overhung centrifugal pump– Between the bearings type centrifugal pump with seal system– Requirements for seal pots with shutdowns on pumps 1000HP– Suction lines must have same MAWP as discharge or protected by PRD– High vibration shutdown on pumps 1000 HP Compressors requirements for:– Vibration Shutdowns– New requirements for SDV’s on intermediate stage suction anddischarge– Shutdown on loss of secondary seal for compressor 1000 HP147

4/5/2017Safety System and ESS Bypassing Bypass Classes (Incorporating & resolving NTL guidance into APIRP 14C)–––––All bypass classes are thoroughly definedExample of various bypass classes are givenRestrictions on the use of various bypass classes are describedAnnunciation requirements for bypasses are definedSpecific time delays are outlined and process for extending these timedelays is provided Automated Bypasses– Automated bypasses are to be maximized in order to minimize thepotential for human error Emergency Support Systems (ESS) Bypassing– Bypassing of ESS related systems defined in more detailSlide 15Open Deck Fire and Gas Systems Open Deck Fire and Gas Systems Open deck gas detection is not currently addressed or requiredin 14C New facilities are installing fire/gas monitoring in the open deck areas ofthe process Within the Emergency Support Systems (ESS) Annex: Provide guidelines for optional use of deck fire/gas coverage Provide set points (alarm and trip), and testing requirements Identify the methodology for installation of gas detectors tosupplement some PSL and LSL requirements PSL/LSL method of leak detection may not be effective for somescenarios, Gas detectors may be a more effective and offer increased safetySlide 168

4/5/2017Concurrent Standards Work ISO 10418 is the international version of API RP 14C, but there arenow large differences between the two standards.– ISO 10418 has attempted to be more performance based but still notrecognized my many countries API 17V Subsea Safety Systems– Provide a clear division for Topsides and Subsea Safety Systems– Maintain a similar proscriptive format– Ensure consistent requirements for shut-inSlide 17Other Changes Low Temperature added to cover high pressure gas Large Rotating Equipment pointed to API 670 Temporary Equipment defined and required to meet API 14C Symbology allowed to match ISA S5.1 Appendix D “Safety Device Testing “ updated and Partial StrokeTesting credited SDV full stroke closure required All Figures and Tables - updated &corrected SAC Tables updated and corrected189
