The Norwegian Petroleum Safety Agency is concerned about the quality of the production vessel in the Johan Castberg oil field after welding defects and design challenges. Equinor replied that these faults had been repaired before the Singapore hull left the shipyard.
In February, the Norwegian Petroleum Safety Agency (PSA) inspected the hull and equipment production of Equinor’s production vessel Johan Castberg.
The audit was notified in October last year and was conducted through Microsoft Teams.
I Audit Report The audit pointed out three differences related to the production ship:
Earlier Monday, Equinor showed the results of an internal investigation of welding defects on production ships. There, the company admitted to the extent to which the error should have been discovered earlier.
-Equinor spokeswoman Esnor Rinde (Esnor Rinde) said about E24 that the mistakes that occurred exceeded expectations.
Rinde is Equinor’s new director of information. She said that the failure of the production ship will be repaired before sailing to Norway, and the PSA record will prove that the conditions have been met.
-Equinor and PSA have a common goal, that is, the production vessel should be safe and the workplace should be safe. Rinde said that Johan Castberg’s hull can only leave the hull after it is satisfactorily completed so that it can meet all requirements and design prerequisites.
PSA requested documentation in its report to ensure that the recommendations were followed and the design should proceed as-is. According to Equinor, they will get it.
-We found that we can better prove that the ship must comply with the design assumptions used before the ship left Singapore. Rinde said that we will submit the necessary documents to the Norwegian Petroleum Security Agency for this purpose.
PSA is concerned about insufficient manufacturing quality. The audit wrote: “Although extensive additional ultrasonic inspections (UTXC) have been carried out, it is expected that Johan Castberg will have more welding errors than other similar equipment.”
-How do you answer?
-Here, the error rate is higher than the normal level at the beginning of the construction, but we found the error rate, Rinde said.
She said that 100% of all critical fatigue areas are covered by the so-called “non-destructive test”, and then 100% cross-check is performed.
