Safety Briefing
• No drills planned today!
• Audible and Visual alarms will alert us
• Don’t panic, we have a plan:
• Follow the lighted “EXIT” signs to the stairwells
![Page 5: Continued Service Workshop - OOCoocmain.theooc.us/Continued Service Forum Presentation_FINAL 08-31... · API RP 2A 22nd Edition API 2MET API 2N API 2EQ API 2SIM –Platform Assessment](https://reader035.vdocuments.us/reader035/viewer/2022082210/5aad4e587f8b9aa06a8e23d0/html5/thumbnails/5.jpg)
Anti-Trust Review
• The Sherman Act and the Clayton Act are federal statutes which make certain agreements in trade restraint illegal. Violators can be subject to criminal penalties and large monetary damages.
• The purpose of antitrust policies is to restrict communications concerning cost, production or other trade sensitive information which could be the foundation for such illegal agreements.
![Page 6: Continued Service Workshop - OOCoocmain.theooc.us/Continued Service Forum Presentation_FINAL 08-31... · API RP 2A 22nd Edition API 2MET API 2N API 2EQ API 2SIM –Platform Assessment](https://reader035.vdocuments.us/reader035/viewer/2022082210/5aad4e587f8b9aa06a8e23d0/html5/thumbnails/6.jpg)
Anti-Trust Review
So we should always:
Avoid discussing cost, production, market analysis or other competitive trade sensitive data
Have an agenda reviewed by own legal counsel
Stick to the agenda
Report to our own counsel any concerns that we have of variation from the agenda
Keep minutes for a record of our discussions

Review - Aging Floaters• Continued service becoming a critical
issue for GOM:
– 11 platforms have been in service 15+ years
– 16 more for 10+ years
– Some have components at or close to original design lives
• Need standardized process for evaluating continued service of floating systems

Floater IM Gaps Identified Q4 2015• No specific riser guidance• Need for consistency of
separate IM efforts with existing SIM process
• No integrated system-level performance criteria– Consistency with 2GEN
philosophy– Overlapping hull / mooring /
riser limit states– Fatigue limits – importance of
single event
• Alignment at overlap points– FSIM / MIM / RIM / SC17 / SC6
Preliminary API SC2 28
Mapping A-D to system-level targets for a floater…?

Floater IM - Progress• Where we’ve been…
– DeepStar example IM documents completed 2015-2016, shared to API
– API SC2 TGs formed for 2FSIM (2016), 2MIM (2015), 2RIM (2016), coordinated under FEAT – Floater Evaluation and Assessment Team
– Coordination workshop with TG members / regulatory agencies held June 8
• Where we’re going…– FEAT TGs continue to work issues / refine draft RPs– Info shares – sessions like today– First editions published in 2017

API Recommended Practice 2FPS – is the principal document that addresses the
Planning, Designing, and Constructing of Floating Production Systems (2nd Ed., Oct 2011)
• Explicitly covers the following types of floating structures
• Monohulls (ship-shaped structures and barges)
• Semi-submersibles, Spars, TLPs
• Applicable to all possible-cycle stages of floating production systems, such as
• Design, construction and installation of new structures, including requirements
for inspection, integrity management , conversion for different use at different
locations and future removal
API 2 GEN is being developed to provide guidance to standards developers
• Establish a framework for implementation in standards that builds on a systems
perspective and offer a conscious approach to risk management over life of
assets
API RP 2SIM - Structural Integrity Management addresses
• Designer’s role in the initial specification and development of the SIM system;
• Expectations on the owner for effective implementation of SIM over life time of
the structure
• FEAT will deliver 3 new standards to expand this portfolio to specifically address
moorings, risers and floating systems and their interfaces with respect to integrity
management.
Topics Standards
Definition of design and analysis interfaces for platform structural design:Hull Design, structural design, load cases, safety categories, factors of safety.

FEAT Overview
Objectives
• Deliver a coordinated set of IM standards by 2Q17 that references a common integrity management frame work
that recognizes and addresses interfaces between floater hull, mooring and riser
• Recognize intent is to deliver an “assessment” (fitness-for-service) document and not a design document
• identify issues that need to be returned to the design document for updates
How, Why & What
• Phase 1: Leverage the Deepstar reports and progress aggressively to develop a Phase 1 set of RPs for 2017
publication.
• Focus on getting the philosophy and common reference frame work codified and capture the highest priority
IM needs.
• Ensure that the FS interfaces are covered; links to 2SIM in terms of performance targets are made keeping in
mind the differences between floaters and fixed structures
• Phase 2 will begin immediately on conclusion of Phase 1 and will continue to address aspects that require further
study and or alignment for implementation

Drivers & Timing for LE Studies
• Best “problem” to solve; resources beyond End of Design Life (EoDL)
• Essential input to field development decisions made today
• Economic enabler for future subsea tie-backs and near field exploration compared to new-build
![Page 45: Continued Service Workshop - OOCoocmain.theooc.us/Continued Service Forum Presentation_FINAL 08-31... · API RP 2A 22nd Edition API 2MET API 2N API 2EQ API 2SIM –Platform Assessment](https://reader035.vdocuments.us/reader035/viewer/2022082210/5aad4e587f8b9aa06a8e23d0/html5/thumbnails/45.jpg)
Drivers & Timing for LE Studies• Emerging regulatory requirements and industry
standards
• Develop a long-term maintenance and project execution strategy around life extension
• Proving technical feasibility and economic viability of life extension is the responsible approach to resource booking beyond EoDL
• 7-10+ years prior to EoDL is not too early!
![Page 46: Continued Service Workshop - OOCoocmain.theooc.us/Continued Service Forum Presentation_FINAL 08-31... · API RP 2A 22nd Edition API 2MET API 2N API 2EQ API 2SIM –Platform Assessment](https://reader035.vdocuments.us/reader035/viewer/2022082210/5aad4e587f8b9aa06a8e23d0/html5/thumbnails/46.jpg)

General Learnings
• No technical “showstoppers”
• Overall Life Extension project economics are very competitive
• Significant investment comes as early as 5 years prior to EoDL
• Changes in maintenance or project strategies can begin as early as 10 years prior to EoDL
![Page 52: Continued Service Workshop - OOCoocmain.theooc.us/Continued Service Forum Presentation_FINAL 08-31... · API RP 2A 22nd Edition API 2MET API 2N API 2EQ API 2SIM –Platform Assessment](https://reader035.vdocuments.us/reader035/viewer/2022082210/5aad4e587f8b9aa06a8e23d0/html5/thumbnails/52.jpg)
Civil / Structural & Marine Learnings
• Tendon fatigue of steel components well understood, longevity of elastomeric flex elements more uncertain
• Mooring system replacement can be expected
• Replacement of SCRs / TTRs due to fatigue is extremely costly (consider production deferment + cost), though early mitigations (e.g. cleaning, VIV suppression) may prevent replacement in some cases
• Internal tank corrosion and CP system depletion are primary threats to hull
• Enhanced inspection of hull / deck is required (ISIP)
![Page 53: Continued Service Workshop - OOCoocmain.theooc.us/Continued Service Forum Presentation_FINAL 08-31... · API RP 2A 22nd Edition API 2MET API 2N API 2EQ API 2SIM –Platform Assessment](https://reader035.vdocuments.us/reader035/viewer/2022082210/5aad4e587f8b9aa06a8e23d0/html5/thumbnails/53.jpg)
Other Discipline Learnings• Strong commitment to painting program is
essential
• Control systems / electronics / field device obsolescence a common theme
• Subsea CP system depletion is a threat
• Umbilical failures are a threat
• Crane replacement can be expected
• Lifeboat / FRC replacement can be expected
![Page 54: Continued Service Workshop - OOCoocmain.theooc.us/Continued Service Forum Presentation_FINAL 08-31... · API RP 2A 22nd Edition API 2MET API 2N API 2EQ API 2SIM –Platform Assessment](https://reader035.vdocuments.us/reader035/viewer/2022082210/5aad4e587f8b9aa06a8e23d0/html5/thumbnails/54.jpg)
Parting Thoughts
• Understanding the technical and financial implications of life extension is a necessity when approaching EoDL
• 7-10 years prior to EoDL is not too early to begin thinking about Life Extension
• A multi-discipline approach is the only way to gain a true understanding of scope and cost
• Above all, the safe continued operation of a facility must reside at the core of any life extension decision!

API 2FSIM – Task Group Terms of Reference
• The 2FSIM Task Group is developing a Recommended Practice API RP 2FSIM for Floating Systems Integrity Management. It is intended that this RP will provide a clear and consistent framework for demonstrating Floating System integrity in a practical and transparent manner.
• The Recommended Practice will be consistent with other related API standards being developed simultaneously, namely API RP 2MIM for Mooring Integrity and API RP 2RIM for Riser Integrity.
• The Recommended Practice will be consistent with existing US regulatory requirements and early input from Regulatory personnel is currently being provided
• The product will be developed for worldwide application to the extent that it does not extend the publishing date. It is acknowledged that the there is a pressing need for this document in the US and that will be our primary focus.
![Page 73: Continued Service Workshop - OOCoocmain.theooc.us/Continued Service Forum Presentation_FINAL 08-31... · API RP 2A 22nd Edition API 2MET API 2N API 2EQ API 2SIM –Platform Assessment](https://reader035.vdocuments.us/reader035/viewer/2022082210/5aad4e587f8b9aa06a8e23d0/html5/thumbnails/73.jpg)
API 2FSIM – Task Group Terms of Reference• The Task Group will use the framework set forth in API RP 2SIM, Structural Integrity
Management of Fixed Offshore Structures, which was published in November 2014. Consistency, particularly in terms of definitions, process, and level of detail will be achieved to the extent that it is practical
• The Task Group will adopt those portions of the DEEPSTAR Report, “Continuing Service Guidance for Aging Floating Infrastructure”, that make sound engineering sense and are properly vetted by the Task Group
• The Task Group will take advantage of learnings from Continuing Service Process, Applications & Regulatory approvals for several of the GOM Floating Systems (e.g. Genesis Spar and Joliet TLP) that have already passed regulatory review
• The 2FSIM Task Group will coordinate with 2RIM and 2MIM through the FEAT team
• API RP 2 FSIM will be ready for ballot by Q2 2017

Philosophy & Approach to IM
• AP-RP-2MIM is intended to be risk based. Reference will be made to standards such as API-RP-2I to cover default inspection approaches as necessary.
• Risk based approaches provide more flexibility than prescriptive approaches, in particular when dealing with emerging or novel technologies or contexts.
• Risk based approaches, when implemented properly, typically result in a more optimized outcome than prescriptive approaches.
• The objective of a MIM Program is to manage the risk of a loss of position event to within acceptable bounds.

Philosophy & Approach to IM
• The underlying risk management approach involves:
– The identification of causes of failure.
– The assessment of the risk associated with one or more causes of failure.
– The development of risk mitigation measures.
– The verification that the intended risk mitigation measures have been successfully implemented and the management of cases where this has not occurred (deviations).

“Ageing is not about how old your equipment is; it is about its condition, and how that is changing over time. Ageing is the effect where a component suffers some form of material deterioration and damage (usually, but not necessarily, associated with time in service) with an increasing likelihood of failure over the lifetime.”
- UK HSE Research Report 509

Uncertainties of Continuing Service
• Analyses are only as good as the input data. (Assuming good methodology)
![Page 123: Continued Service Workshop - OOCoocmain.theooc.us/Continued Service Forum Presentation_FINAL 08-31... · API RP 2A 22nd Edition API 2MET API 2N API 2EQ API 2SIM –Platform Assessment](https://reader035.vdocuments.us/reader035/viewer/2022082210/5aad4e587f8b9aa06a8e23d0/html5/thumbnails/123.jpg)
Uncertainties of Continuing Service
• Inspectability poses significant barrier to Continuing Service.
– Inspections takes care of ‘what you don’t know’.
– Removal of marine growth is time consuming and may obscure in-situ inspection.
– Acceptable (riser) defects during fabrication may no longer be acceptable due to defect growth.
