Hugh Shaw, the Government representative in charge of the operation, said it was necessary to keep people away from the beach for their own safety.

Diggers and other cutting equipment remain inside a 500m cordon around the site, opposite Anchorsholme Park, and could pose a risk if people were to interfere with it.

Mr Shaw, the Secretary of State's representative, said: "The exclusion zone will remain in place until the last piece has been removed and sonar scanning has been carried out to check there are no remains on the beach.

"We do not want any local people and particularly children to be put at risk.

"We thank the public for their continued support and understanding."

The last piece of the ferry is expected to be removed next week.

Sub-contractors PGC Demolition, who have planned and carried out the operation to cut the 6,000 tonne ship to bits, had hoped to remove the final piece last week.

But bad weather and tidal conditions caused the delay.

Despite this, Mr Shaw said he was thrilled by the work of the contractors and delighted the environment had not been affected by the clean up.

He also revealed the process which saw the ship cut up on the beach could become an example to follow elsewhere.

"When I proposed that the ship would be cut up on the beach, there was concern due to the amount of oil on board," he said.

"But that was dealt with through working together and, with a lot of planning, has ultimately proved successful."

Gordon Whitaker from the Environment Group said he was satisfied with the way the operation had been carried out and that Blackpool's beach and its water had not been adversely affected.
