Ship righted and afloat after toppling in Leith dry dock

An investigation into the cause of the incident on 22 March is ongoing

A US Navy vessel which tipped over in a dry dock in Edinburgh has been righted and is now afloat.

Two tugs manoeuvred the Petrel around Imperial Dock in Leith on Tuesday afternoon.

The 3,371-tonne ship tipped over on 22 March, sparking a huge emergency operation and leaving dozens injured.

The dry dock is thought to have been flooded to right the ship on Sunday, when pictures of the process were posted on social media.

The vessel had been leaning at a 45-degree angle.

A US Navy spokesperson said work was undertaken to stabilise the ship, which was then moved along the pier to allow further evaluation and repair work to be undertaken.

The Health and Safety Executive (HSE) launched an investigation after the Petrel became dislodged from its holding.

NHS Lothian said 23 people were treated in hospital and 12 at the scene of the incident.

A HSE spokesperson said: "A HSE team is continuing to work with Police Scotland on the ongoing investigation of this incident."

The Petrel had been moored at the dockyard since 3 September 2020 due to "operational challenges" from the pandemic.

It was once owned by the late Microsoft co-founder Paul Allen, who bought the ship to locate historically significant shipwrecks.

In 2022 the Isle of Man-registered vessel was sold to the US Navy, and is now operated by American-owned firm Oceaneering International.
