Offshore drilling contractor Seadrill Limited has revealed that a termination notice has been received for the West Mira rig from Wintershall Dea.

Wintershall Dea terminates West Mira rig after x-mas tree incident

The West Mira has had a period of unproductive time following an equipment failure on 19 March 2021. Northern Offshore is the owner of the rig and Seadrill is the operator.

To remind, an incident on the West Mira rig occurred on 19 March during a lifting operation while the rig was working on the Nova field for Wintershall Dea.

While lowering a x-mas tree from the West Mira, the winch wire snapped when the tree was five metres below the sea surface.

As a result, the x-mas tree sunk to the seafloor 368 metres below water level.

No one was injured in the incident, but the drilling operations halted and an investigation was launched.
