Ifølge aftale fremsendes hermed vedlagt den endelige rapport fra review ud·ført i perioderne 27.-29. september 2011 og 17.-19. oktober 2011, af LRScandpower Ltd. (tidligere L1oyd's Register EMEA),p~alle vore offshore og on·shore installationer.Rapporten bekræfter, i lighed med den første rapport fra marts 2011, at Ma·ersk Oil har etableret procedurer, som sikrer overholdelse af de vilkår, der fin·desivores udledningstilladelser for produktionsenhederne.Rapporten bekræfter ligeledes, at de anbefalinger som Maersk Oil i brev af1.marts 2011 lovede at implementere, nu er gennemført.De anbefalinger, der blev beskrevetiførste rapport, og som nu er implemen·teret, kan opdeles i følgendeområder:OiW procedurer:Disse er opdateret, så der findes en ensartet procedure for analyse og plat·formspecifikke procedurer for prøvetagning og rapportering iht. anbefalinger·ne. Procedurerne er nu mere robuste, og reducerer derfor signifikant risikoenfor misforståelser og fejl.Data integritet:Der er indført håndskrevne logbøgerp~alle laboratorier, og der er etableretprocedurer for onshore databehandling. Der udføres i tillæg verifikation af dataflere gange årligt af interne og eksterne auditører.Medarbejdere:på Tyra E har initiativet til forbedring af kommunikationen mellem medarbej·dere og ledelse været en succes, da medarbejdertilfredsheden er steget mar·kantp~Tyra E. Endvidere er der etableret en træningsmatrix for laboranter,og der gennemføres "On-the-job" træning for nyansatte laboranter.

EXECUTIVE SUMMARYIntroduction and Scope of WorkDuring December 2010, a series of newspaper allegations raised a number of significantconcerns within the Maersk Oil operations in Denmark. As a result, Lloyd's Register EMEAwas engaged to conduct an independent critical review of procedures relating to producedwater management.In September 2011, LR Scandpower Ltd. (formerly Lloyd's Register EMEA) was contractedto conduct a follow-up review of the status progress since the February review. This reportoutlines the findings and recommendations from our return visits to the Esbjerg office and thefollowing installations:•••••••Tyra West.Tyra East.Dan.Halfdan A.Halfdan B (note: Halfdan B is newly commissioned and was not included February2011 review).Gorm (including Skjold).Harald.
In line with the previous independent review, this follow-up review evaluated existingdocumented processes and procedures, and compared their implementation onshore andoffshore to recognised industry practice, best laboratory practice. The review alsocommented on compliance with the current OiW discharge permits for operating in theDanish sector of the North Sea. It included a series of interviews with workforcerepresentatives who developed and used these processes and procedures. Additionally, thereview verified a number of samples of reported concentrations, following the path along datatransfer points.FindingsCommendationsAn enhanced suite of OiW procedures has been implemented, including newlyestablished procedures for monthly, quarterly and annual reporting.Laboratory logbooks have been introduced on all platforms in order to improve datatraceability.Platform specific OiW procedures have been developed with the involvement of theLaboratory Assistants.In compliance with the new permit expectations, Maersk Oil Denmark has exploreda number of options relating to OiW process control monitoring.Excel workbooks now contain a log for data changes, increasing the degree of datatransparency.Onshore personnel track the daily and monthly averages using the EBJ-OLSreported data.

DNV has recently conducted some OiW data verification through ISO14001certification audit and Environmental Statement verification.A third party survey has been completed to calculate the estimated level ofuncertainty associated with the measurement of volume for produced waterdischarges.Uncertainty levels have been reduced with the introduction of more accuratelaboratory glassware.A training matrix for Laboratory Assistants is in the process of being implemented,accompanied by training plans for individuals.Comprehensive recruitment processes for Laboratory Assistants includes a writtentest.A newly hired Laboratory Assistant was subject to a three day on-the-job trainingprogramme.The profile, roles, and responsibilities of Laboratory Assistants were the focus of arecent onshore workshop.A good team culture exists on some platforms between the Laboratory Assistantsand production crews in seeking to optimise OiW treatment.A culture of researching and initiating improvements exists on some platforms.There was a widespread willingness to change and improve the OiW workingpractices and ultimately, the results.In general terms, LR Scandpower Ltd. was able to consistently verify data from thepoint of sample collection to external reporting, following all data transfer points.Areas for Improvement/RecommendationsThe follow-up review identified eight areas of potential improvement; the associatedrecommendations are summarised below.OiW Procedures1. Enhance the clarity in the platform specific procedures relating to sample-takingduring (routine) abnormal conditions (e.g. when the centrifuge discharges “shots”).Additionally, platform specific procedures should also be updated to reflect thecontinuous monitoring equipment, when commissioned.2. Enhance the clarity of OPM 2B Part 3 OiW procedure to fully address theabsorbance acceptance criteria. Clear instructions should also be provided foraction in the event of unstable absorbance readings, to ensure that all absorbanceraw data is included in the OiW calculation.3. Provide cool storage for Halfdan A samples in order to ensure sample integrity in theevent of transport delays to Halfdan B (for analysis).4. The OPM 2B Part 3 OiW procedure states that during sample extraction, the sampletemperature should be approx 20�C (i.e. room temperature). Across the DUCinstallations, there is no consistent method for measuring room or sampletemperatures. Provide a consistent method to achieve this and include it within therevised OiW procedures.5. OPM 2B Part 3 procedure should be updated to make accommodation for thepotential formation of emulsions.

Integrity of Data6. Ensure that laboratory logbooks are consistent in structure and content. This shouldinclude:i. Page numbers.ii. Legible data entry and comments.iii. Discontinuation of the use correction fluid.iv. The requirement for changes and corrections to be struck-through andinitialled.7. Enhance security on platform specific Excel worksheets (i.e. password protection).Verification of Processes8. Improve efforts to fully capture data anomalies during integrity sense checks that areconducted as part of the monthly reporting process.9. Efforts should be made to enhance engagement at supervisory level in theverification and quality assurance of OiW management activities and practices. Forsome Supervisors, this will require a raised awareness of the OiW sampling,analysis and reporting procedures and processes.10. The scope of the HSE audits should be extended to ensure that issues relating toproduced water management are adequately assessed, so that value addingfeedback and verifiable data checking can be delivered on the topic.11. Ensure that the existing Force Technology audits include OiW data verification.12. Introduce a process to verify that on-the-job training is taking place offshore and isbeing applied effectively to sample collection and analysis tasks.Variability of Reported Concentrations13. Maersk Oil should encourage the Technicological Institute, to seek ISO17025accreditation for the OSPAR and Wilks OiW analytical methodologies.14. Method validation should be conducted in order to understand the Limit of Detection.15. In order to understand whether balance check results are acceptable, clearperformance limits should be calculated and adhered to.16. Maersk Oil Denmark should implement structured laboratory Quality Controlprocesses for OiW analysis. This could be in the form of analysing knownconcentrations (i.e. standards), OSPAR calibration checks, or 'Round-Robin'analysis carried out by all the laboratories.Commentary on OiW Permit Compliance17. Maersk Oil Denmarkmustenhance the offshore performance in meeting therequirements of the discharge permits in relation to OiW sampling and analysis.Onshore management should provide more robust monitoring processes. Offshore,the critical importance of permit and legal compliance must be reinforced to allindividuals engaged in, and with influence on, produced water management.

Competency Assurance18. Ensure that role descriptions for all personnel engaged in produced watermanagement activities are consistently defined.19. Enhance the training matrix to fully address OiW detail and knowledge requirementsto make it value adding for those engaged in produced water management. Thisshould also recognise varying competence levels required, including: awareness,knowledgeable and specialist.20. Enhance the competency assurance processes to include the verification of on-the-job training in OiW management.21. Verify the competency levels required for temporary (contracted) LaboratoryTechnicians.Culture and Climate22. The attitude and motivation of those working in OiW management is critical to theeffectiveness of the overall processes. Maersk Oil Denmark must reinforce thecriticality of permit/legal conformance in order to enhance a culture of complianceand performance improvement relating to mandatory HSE requirements.Data Verification Sampling23. In order to improve the degree of transparency and traceability of reported data,Maersk Oil Denmark should ensure that:i. Samples are collected on time.ii. Discrepanciesbetweensampletimesinlaboratorylogbooks/spreadsheets/OLS are minimised.iii. Provide clear comments when concentrations exceed 20mg/l.iv. Updates of the Wilks calibration is provided to the Laboratory Assistants ina timely manner.
