Two giant plastic pipes have washed up on the East Anglian coastline.
The bore pipes, one of which measures almost 500 metres in length, are among 12 which broke free while being towed to Algeria this week.
The Maritime and Coastguard Agency said it has been working with the industry involved, local government, environmental regulators and port authorities to resolve the matter.
All of the pipes have now been brought under control, with some re-attached to towing vessels and others anchored just off shore, attended by guard vessels.
The Norweigan-made tubes washed up on beaches at Winterton and Horsey in Norfolk earlier this week and were revealed at low tide.
The coastguard say they pose no danger to the public and will be relocated offshore north of Lowestoft ahead of towing them back to Norway.
