IMP-1: Digitalization of the Environmental Sensitive Valves (ESV) system

Good if paper/binder versions are digitalised

16.10.24: Report sent.
Week 46: Noble ref.: RCAL-102863
12.02.25: According to K. Kludzinska, the system is operational in COW, but training sessions will be needed for full digitalization implementation.
14.03.25: Training with CoW team to be agreed with OIM – extended to 30.05.25. We acknowledge that this topic is followed up and close the finding.

IMP-2: ppm registration on oily water from bilge

01.11.24 (adjust alarm)
31.12.24 (implement exact measurements)
15.01.25 (update measurement program)

16.10.24: Report sent
04.11.24 update from rig: – It is decided we will stay with our 15PPM limit and keep sending in analysis ow treated bilge water on a monthly basis. This in accordance with MAPOL 15ppm and HAVTIL 30ppm. Rig does not operate in special protected areas with lower requirement, and to lower the alarm limit does not give any improved quality of the ZDU function. Noble ref.: RCAL-103015

IMP-3: Incorrect information in NINV “INV-14-0038-001-80” (must be seen in conjunction with IMP-2)

Update procedure to reflect the right ppm

16.10.24: Report sent
04.11.24 Feedback from rig: ZDU & Decanter UNIT in Cantilever is decommissioned and not in use, which this procedure reflects. Noble ref.: RCAL-103014

IMP-4: Storage of chemicals in sack store that are not included in relevant/current permit

Remove the chemicals (send to shore)

16.10.24: Report sent
22.10.24: Asked for status
04.11.24: Feedback from rig: The Halliburton chemicals in sack store are now marked belonging to Halliburton and tagged “do not use”. Noble ref.:RCAL102864

IMP-5: No label on IBC tank at Port hose station

Put label on

16.10.24: Report sent
04.11.24 Feedback from rig: IBC cube properly marked with both content and IMDG signs. Noble ref.:RCAL-103010

IMP-6: The washing detergent used on NINV is not commonly used on the NCS

Cleanrig CHP suggested and tried without success. Recommend to try Microsit Polar

16.10.24: Report sent
04.11.24: 200 ltr drums of CLEANRIG CHP ordered from the rig on 30/sep, this has still not been received onboard. Noble ref.: RCAL-103011
21.03.25: All 6 crews have tested and approved CleanRig CHP, and have been using it in replacement to Masawa Max. CLOSED

IMP-7: Treatment of the left-over grease from the leg levellers

Secure that this waste is treated properly and labelled correct

16.10.24: Report sent
“02.11.2024 MDA: The following received from the Logistic Cordinator – QUOTE: Could not find any labels BUT sourced some in environment STD – I have now ordered and we will see when arriving. I was on board when DNO Environmental audit took place and it is correct I was not able to find any labels – for some reason. Anyway just to point out again – it is dangerous waste BUT not under IMDG/ADR with clarifications. We have always used the hazardous waste numbers they refer to when doing waste declarations.”
However – we will move forward exactly same way as always BUT this time with a label on drums and NOT hand written. UNQUOTE – Labels ordered on PR 1127629.”

IMP-9: Shaker screens, waste handling and screen washer

Improve tubings on screen washer and secure proper handling of the waste

16.10.24: Report sent
11.11.24: The screen washer, has, as described, never been effective at cleaning screens. It has been checked, and does function as designed, which is poor. Research into alternative/ improved screen washers has been done, but to date with no positive outcome. Even with a fully operative screen wash system, consideration must be given to manual handling and the transport of the screens to any cleaning unit. Again, after study, this has not been resolved. Screens would always have to be prewashed prior to removal from shaker and transfer to a cleaning unit. If this was not done, then the weight of the screen and slip hazard from spills would be a credible risk to the operators. To counter HSE issues when cleaning screens (aerosols of water/OBM) with power washer, then battery powered clean air filter units are always used. Screens are power washed prior to scrapping. Noble ref. RCAL-103017.

IMP-10: Labelling
