45VedlikeholdDen ansvarlige skal sikre at innretninger eller deler av disse holdes ved like, slik at de er i stand til utfre sine tiltenktefunksjoner i alle faser av levetiden.

46KlassifiseringInnretningers systemer og utstyr skal klassifiseres med hensyn til konsekvensene for helse, milj og sikkerhet av potensiellefunksjonsfeil.For funksjonsfeil som kan fre til alvorlige konsekvenser, skal den ansvarlige identifisere de ulike feilmodiene medtilhrende feilrsaker og feilmekanismer, og ansl feilsannsynlig-heten for den enkelte feilmodusen.Klassifiseringen skal legges til grunn ved valg av vedlikeholdsaktiviteter og vedlikeholds-frekvens, ved prioritering av ulikevedlikeholdsaktiviteter og ved vurdering av reservedelsbehov.

47VedlikeholdsprogramFeilmodi som utgjr en helse-, milj- eller sikkerhetsrisiko, jf. 44 , skal forebygges systematisk ved hjelp av etvedlikeholdsprogram.I programmet skal det inng aktiviteter for overvking av ytelse og teknisk tilstand, som sikrer at feilmodi som er underutvikling eller har inntrdt, blir identifisert og korrigert.Programmet skal ogs inneholde aktiviteter for overvking og kontroll av feilmekanismer som kan fre til slike feilmodi.

48Planlegging og prioriteringDet skal utarbeides en samlet plan for utfring av vedlikeholdsprogram og korriger-ende vedlikeholdsaktiviteter, jf.styringsforskriften 12 .Det skal foreligge kriterier for setting av prioritet med tilhrende tidsfrister for utfring av de enkelte vedlikeholdsaktivitetene.Kriteriene skal ta hensyn til klassifiseringen som nevnt i 46 .

Risk Based Inspection Framework:

Secure optimum availability at acceptablerisk

Prioritize inspection efforts on the itemsdriving the risk

Document the evaluation leading todefinition of inspection and condition

monitoring programs Can be used to inform relevant stake

holders, e.g. governments, owners,management, technicians

An inspection framework based on RBI,and formalized through implementation ofRBI and inspection management software,as well as computerized maintenancemanagement system, gives a holistic viewand is a powerful tool, for managementand reporting of asset technical condition

RBI work process: Condition monitoringprogram

Establish integrity operating envelopes inorder to verify validity of RBI analysis andcheck PoF drivers against pre-defined limits

Define monitoring parameters on instrumenttag level / test points etc.

Monitoring to be focused on significantinfluence factors, e.g:

Corrosion / erosion probes; e.g. erosion

coupons, corrosion coupons, bacteriacoupons

Vibrations / stress monitoring

Process parameters; e.g. pressure,temperature, velocity, pH, oxygencontent, fluid conductivity, CO 2, H2S etc.

Performance parameters; e.g. heattransfer, pressure drop, chemicalinjection pump availability

Cost-benefits of process- and condition monitoring forstatic mechanical process equipment: a case study It is recognized that heat recovery units (HRSG) systems have

experienced significant problems due to leaks from water / steampiping and heat exchangers. Main degradation mechanism have been stress corrosion cracking

and corrosion fatigue in stainless steel pipes (SS316 / SS321) andflow assisted corrosion in carbon steel pipes.

Cost-benefits of process- and condition monitoring forstatic mechanical process equipment: a case study (cont) It has been recognized that monitoring of significant influence

factors (conductivity, pH, oxygen content, nitrite content) andacting on out of spec parameters could have prevented leaks Leaks and shutdown of steam loops implicates that electricity has

to be generated from gas driven generator Calculations from one installation offshore Norway indicates an

extra cost of $ 13-17 mill per year due to lost heat generation, aswell as $ 35-50 mill in modification costs

Aker Solutions in brief Who we are and what we do

Risk Based Inspection Dynamic optimisation of inspection plans / integrated planning Non-Intrusive Inspection a significant contribution to optimisation

8/9/2019 O_Bjaanes

30/33


Non-Intrusive inspection (NII) Where the RBI identifies internal degradation mechanisms which can be

followed up through periodic inspection, it should be evaluated whether

inspection can be performed non-intrusively Non-Intrusive Inspection means inspection from outside, without breaking

the integrity. Performed during production (or during shut down) Assessment can be performed in accordance with DNV RP-G103, Non-

Intrusive Inspection AkerSolutions have developed a NII screening methodology considering

Technical issues (design / construction data, inspection history etc) HSE issues Business issues (cost benefit evaluations)

Why NII? Reduce need for entering of confined space (safety of personnel) Increase production availability More flexibility in planning of shut down work

NII assessment capabilities will be implemented in AkerSolutions RBI andinspection management software

Cost-benefits of Non-Intrusive Inspection: a case study


::.

Item Electrostatic coalescer, tag No. XXXX-VJ20001A

Presumptions

andexperience

Entering tank for IVI will be done outside revision stop, while

producing through parallel coalescer In order to secure acceptable water in oil content, the

production is reduced by 3-5000 barrels per day for about 20days

Evaluation IVI implicates an accumulated deferred production of $ 5-10

mill while NII does not affect the production The inspection cost for IVI and NII is about the same ($ 0.22

vs. 0.18 mill) Manpower required for IVI and NII is about the same (4 vs. 5

persons, about 20 days) The risk related to entering the tank is significant wrt.

personnel, and redundancy is lost while performing IVI. Riskrelated to NII is low

Conclusion There is a potential for significant savings, both in terms of riskand production, by implementing NII
