The waters where we will explore are ice-free at this time of year, and the ice edge zone is some 400 kilometres away in the summer. If sea ice should still get closer than 50 kilometres to the rig – due to wind or currents from the North– we will move the rig. We will constantly monitor the movements of the ice.
The authorities have set as an important requirement that drilling in oil-bearing layers cannot take place closer than 50 kilometres from the marginal ice zone. The marginal ice zone is an area that is covered by at least 10 % ice and monitored from day to day by the Norwegian Meteorological Institute. No exploration drilling will therefore take place if sea ice is drifting towards the drilling location. In practice, this is handled through extensive, thorough monitoring of large ocean areas and sea ice monitoring.
If sea ice approaches, drilling activity will be stopped until the ice is more than 50 kilometres from the drilling location. Sea ice closer than 50 kilometres will necessitate interruption of the drilling operation and delay of the exploration activity. It takes only a few minutes to safely disconnect an exploration rig.
