Specialist cranes are on site as inquiries continue into how a ship owned by the US Navy toppled over in an Edinburgh dry dock, leaving 35 people injured.
A major incident was declared after research vessel Petrel became dislodged from its holding and tipped over to a 45-degree angle at Imperial Dock in Leith last month.
Officers remain at the scene, and on Thursday a police car could be seen as workers operated two large Mammoet cranes and moved around the stricken 3,371-tonne ship.
Both the Health and Safety Executive (HSE) and Police Scotland said investigations into the incident, which happened on March 22, are continuing.
A HSE spokesman said: “Specialist inspectors from HSE are assessing the technical aspects of the structural collapse and continue to work with Police Scotland on the investigation into this incident.”
The 76 metre-long Petrel was once owned and outfitted by the late Microsoft co-founder Paul Allen but was sold by his estate in 2022.
Mr Allen bought the ship to locate historically significant shipwrecks and it discovered around 30 sunken warships, including the Japanese Imperial Navy’s IJN Musashi.

After it tipped over, a huge emergency service operation was launched, which included trauma teams, an air ambulance and the Coastguard, who all worked for hours to rescue people off the ship.
Some 35 people were injured, with 23 taken to hospital and 12 others treated at the scene.
A Police Scotland spokesman said: “Officers are working with the Health and Safety Executive.
“Inquiries are ongoing to establish the full circumstances.”
In a statement on Dales Marine Services’ website, it said it “continues to liaise with the emergency services and relevant authorities in dealing with the incident” and at this time it “cannot comment any further”.
