Video: Rescue vessel battles 100ft North Sea waves during Storm Gertrude

This dramatic footage shows just how terrifying life in the North Sea can be.

The footage was captured from the bridge of an ERRV (Emergency Response & Rescue Vessel), around 100 miles north-east of Shetland on January 29.

Some of the waves are estimated to be around 100-foot high – crashing against the vessel, rocking it from side to side and soaking the entire deck.
