A-5: Make sure that routines are in place for Cement unit handover between wells – review handover documentation (Baker cement unit) and verify cement unit maintenance system towards SLB

Maintenenace review scheduled for Apil 2nd. Handover meeting confirmed by SLB.
Maintenance review identified several observation. Action closed here and follow-up in ARV report 8537.

A-6: Perform rig survey and identify interface for new installed equipment

Rig surveys performed for non incumbent services from service provides. Soiltech, Roxar, SLB, Expro and Halliburton performed the rig survey and report distributed for follow-up and close out. No further followu-up required towards SLB and Roxar. Expro CLMA technology not selected for Bestla – no further follow-up required. Halliburton required further follow up and will be managed through the weekly follow-up meetings with the Bestla D&W teams. Soiltech interface findings to be followed up with Sval in project meetings after the report is issued end of February.

Verification of the crane and lifting routines identified a gap in the capability of the offshore Technical responsible to perform his duties towards verification of documenation and certification of lifting equipment provided by all parties to DSY. Weak organizational barrier which could lead to incidents or accidents.

A-7: To perform the operator’s “see it” duty, it is strongly recommended to perform onshore verification of lifting equipment and documentation by a competent third party before lifting equipment is mobilised offshore and documented through a compliance certificate form the competent third party.

Experience transfer meeting with Vår Energi arranged to exchnge the experiences from the onshore lifting verification process implemented by VE after a serious dropped object incident during the PP&A campaign on Jotun. Learning from incidents and accidents is key to ensure avaoidance of re-occurance and hence why the intention is to duplicate the verification process implemented by Vår Energi.
Conclusion from meeting: Lifting verification to be implemented on both OKEA and Sval operations and quote requested from Oceaneering Asset Integrity
Action closed in this rig intake and verification to be implemented upon issue of PO. Quote received and accepted by both Sval and OKEA.

A-8: Evaluate need for additional air monitoring (add on to Furuno)

Odfjell has implemented a operational practice / guideline on how to manage drone activity.
No further actions taken as the drone activity on the NCS has declined. Should drone activity increase over time this add-on technology will be further evaluated.

A-10a: OKEA Marine and base manager Morten Veiset to verify the hook and lifting ring on PSV on contract with the logistics pool from OKEA
A-10b: WE logistics Johan Kjos to verify the hook and lifting ring on PSV that will come on contract for the SVAL PP&A operations.

DSY has a Henriksen lifting ring see attached.
On Bestla there is no requirements towards a dedicated standaby vessel or PSV therefore this actions is closed.

Section milling is a potential tertiary contingency solution. This operations has never been conducted on DSY and hence why a swarf handling risk assessment is to be required during the pre-operational planning phase.

A-13: Conduct swarf risk assessment for Vale

Swarf Risk assessment Incorporated in the integrated project plan for Sval and this plan will be followed-up in bi-weekly meetings. No further follow-up in this ARV plan.

A-14: WSOG to be prepared by Odfjell

Mooring and riser analysis established for OKEA Bestla – WSOG received see attached

Mooring lines on both Vale and Bestla are shallow due to the water depth at this location. Collision between visiting PSV vessels and the shallow mooring lines can be avoid by installing Nav-packs on the visiting PSV ounder contract during both Sval and OKEA operations.

A-16a: OKEA Marine and manage manager Morten Veiset to evaluate to have the PSV`s be fitted with NAV-Pack from rig pos. supplier to visually have dynamic updates of mooring lines to avoid contact with mooring lines during OKEA Operations
A-16B: Marine advisor Stian Engvik evaluate to have the PSV`s be fitted with NAV-Pack from rig pos. supplier to visually have dynamic updates of mooring lines to avoid contact with mooring lines during Sval operations

Response from OKEA: Navpack evaluated with OKEA vessel captains on contract. Marine personnel do not see the value of this as the same objective can be achieved through the Master standing Order in combination with the DSY datasheet which visualizes the mooring spread on the location. Additionally with OKEA joining the NLP project in principle no dedicated vessels are planned for. Instead the main logistics supply stratgey is managed through a logistics pool with several vessels suplying the operations in the Tampen area. Having Navpacks instaled on al vessels is seen not doable.

Odfjell does not periodically perform the drawdown test as per Norsok D-001 which refers to API 53. Not required in Norsok D-010. A drawdown test as per D-001 is to be perfromed as part as the first pre-deployment test before commencement of operations on Bestla Development.

A-17: Accumulator drawdown test to be performed before the BOP is installed on the WH on Bestla

Drawdown test to be performed before BOP deployment on Bestla and included in well control bridging document

Risk ID 10 and 11.
Cyber security.
Verify adequate IT security/firewalls

OKEA and Sval IT to validate Odfjell / Starlink IT system through a verification.
OKEA/ SVAL IT to verify firewall system maintained through Speedcast / Option

Verification perfromed by OKEA IT towards OD and Oceaneering. New remote scope identified towards Baker Hughes for remote operating tractor and a verification towards Cyber security is agreed to be included but pending. Baker IT verification performed and report issued for approval . Doc no OKEA-BRS-ITI-REP-0279.

Risk ID 22.
Medical preparedness evaluation to becompleted by OKEA company doctor

OKEA Company doctor to verify medical preparedness:
– check of hospital, pharmaceutical routines, EKG routines and medevac procedures.
– Review relevant documentation
– Assess need for offshore verification

OKEA company doctor report received and issued to OD for review.
Sval company doctor attachement to AfC pending. Received and included in AfC.
