The incident occurred during plugging of a subsea well on the Troll field.

The work led to water and gas flow onto the drill floor and into the shaker room. The facility was automatically shut down and the crew on board mustered in line with procedure. The well has now been isolated.

Investigation
Havtil takes a serious view of the incident and has initiated an investigation into the activities and participants involved prior to and during the incident. The investigation will accordingly include Equinor (operator of the Troll field), Odfjell Drilling (rig owner/drilling contractor) and Baker Hughes (main service provider).

The purpose of the investigation is to clarify the chain of events and underlying causes, so that both the industry and the authorities can learn from the incident.   

In connection with the investigation, we will:

  • Carefully review the chain of events.
  • Assess the actual and potential consequences.
  • Assess direct and underlying causes.
  • Identify non-conformities and improvement points in respect of the regulations (and internal requirements).
  • Publish the results of the investigation.
  • Contribute to the transfer of experience and lessons learned to other industry participants.

The investigation will be summarised in a report to be published on havtil.no.
