The tug DUTCH PEARL and the rig VAGANT leave Irvine's Quay in Hartlepool.

The rig has been towed into port after suffering an 'incident' in the Tees Bay last week. The rig was evacuated after two of its four legs became stuck on the seabed.

The vessel was carrying out survey work for a planned offshore wind farm and got into difficulty in the early hours off Redcar.

The Hartlepool lifeboat and the tug took 16 of the 19 crew to shore amid fears the rig might be flooded by high tides.
