A floating café in Bristol which sank overnight is being retrieved from the harbour this week.
The Greenshank plunged into the water at its mooring near SS Great Britain at around 3am on June 15 following a "catastrophic failure," taking the barge it was attached to down with it.
Divers from Caerphilly-based Edwards Diving Services (EDS) carried out an underwater assessment of the two vessels the following day to determine how to get them out, and have now returned to begin the salvage job.

Specialists have attached airbags to the two boats which will be inflated later this week to raise the vessels above the water.
This is expected to happen on Thursday or Friday.
The boats will then be towed to the nearby Albion Dry Dock where they will be assessed and restored, hope Bristol Packet, which owns them.
EDS diving supervisor Marcus Corderoy told Bristol Live earlier this month the fact the two boats are leaning into each other on the surface of the harbour could make the retrieval process slightly more challenging.
Along with Portishead-based Advance Marine, which will assist with the retrieval, EDS plans to separate the two narrowboats before inflating the airbags to lift them.
It is still not known why the floating café, which opened in 2017 following an extensive refurbishment from its owners Bristol Packet, sank.
The cause will be established once the boats have been taken to the Albion Dry Dock, it is understood.
EDS was also tasked with retrieving the Roehampton boat in August 2017, which sank in its mooring near the Mud Dock café after a gas explosion.
