Twenty-five people were injured when a ship tipped over in a dry dock in Leith, Edinburgh, the Scottish Ambulance Service has said.
Fifteen people were taken to hospital while a further 10 patients were treated and discharged at the scene on Wednesday morning.
The ambulance service said 11 patients were taken to Edinburgh Royal Infirmary and four to Western General Hospital.
The Scottish Ambulance Service sent five ambulances, an air ambulance, three trauma teams and other resources to the scene.
Pictures show the Petrel leaning at a 45-degree angle.
NHS Lothian earlier said it was “on standby to receive a number of patients” at the A&E department at Edinburgh Royal Infirmary from the scene and urged others not to attend unless in an emergency.
The 76m (250ft) Petrel, a research vessel, was previously bought and outfitted by the late Microsoft co-founder Paul Allen but is no longer owned by his estate.
A spokesman for the ambulance service said: “We received a call at 0829 hours today to attend an incident in Leith.
“We have dispatched five ambulances, an air ambulance, three trauma teams, our special operations team, three paramedic response units and one patient transport vehicle.
“We transported 15 patients to hospital; 11 to Edinburgh Royal Infirmary and four to Western General Hospital. A further 10 patients were treated and discharged at the scene.”
A Police Scotland spokeswoman said: “Officers and emergency service colleagues are responding to an incident at Imperial Dock in Leith, Edinburgh, whereby a ship on dry dock has become dislodged from its holding.
“The public are asked to avoid the area to allow emergency service access.”
Leith councillor Adam McVey said the ship became dislodged in strong winds and he described the incident as “terrifying” for those on board.
He tweeted: “Emergency services are responding to a major incident at Leith docks – a ship has been dislodged from its holding in strong winds.
“Terrifying for those on board, my thoughts are with those who’ve been injured & hope everyone recovers quickly. Please avoid area.”

Jackie Campbell, NHS Lothian acute services chief officer, said: “We’re on standby to receive a number of patients at the Royal Infirmary of Edinburgh’s A&E department following a major incident at Imperial Dock in Leith.
“We have been reviewing the current capacity at the RIE, with support from other sites, to accommodate these patients.
“Given the expected pressure on the site, we urge people not to attend A&E at the Royal Infirmary of Edinburgh unless it is an emergency.”
