An oil rig which ran aground on Lewis is set to undergo safety checks after a 54-mile journey.

The Transocean Winner went adrift during a storm on August 8 and grounded near Carloway.

Two tug boats were hooked up to the rig on Monday night and towed it to Broad Bay on the far side of the island.

Travelling at a speed of less than two knots, the tugs took nearly two days to arrive.

Eight anchors have been laid out in Broad Bay to hold the Transocean Winner in place while engineers examine the rig.

Hugh Shaw, the secretary of state's representative for maritime salvation and intervention, said: "The tow has taken longer than anticipated.

"We have been clear from the outset that we would not compromise the operation in any way so I am delighted that the 54-mile transit has been successfully completed without incident."

About 53,000 litres of diesel leaked from its ruptured fuel tanks following the grounding, most of which is thought to have evaporated and caused no harm to the environment.

A temporary exclusion zone remains in place at Dalmore, where officials have been working to ensure no debris has been left behind.

A half-mile exclusion zone is also in place around Broad Bay.
