Residents in the area said they heard a “massive explosion” in the ship while passing the docks.

One wrote on social media: “Driving past a ship earlier and hear this massive explosion. Like thunder going off inside.”

Hannah Mortem said noise coming from the ship made her jump.

“I’m over in Shotley and it made me jump and the shelving shudder, it was so loud,” she said.

“Rest in peace and thoughts with the affected families.”

Mark Mitchell said he heard the explosion from as far away as Rushmere St Andrew, while Dave Franklin said he heard and felt it on the Shotley Peninsula just after 11pm.

Mr Mitchell, who lives close to the Westerfield sports ground in Holly Lane, said: “I was standing at my front door having last smoke before going to bed then I heard the explosion clearly in the distance, my wife who was in bed also heard it through the double glazing.”

Felixstowe deputy mayor Nick Barber said he was “shocked” by the news.

“I am saddened by this, it is a real shock,” he said.

“I am sure most of the town will feel the same, just so sad for those involved.

“These types of things very rarely happen in the town and as long as I can remember I have never recalled anything of this kind happening on a ship rather than the tragic incidents we occasionally get on the dock side.

“I used to work on the haulage side down at the docks and I have never heard of anything like this happening before.

He added: “It is very, very rare incident and on behalf of the town and the council I would like to send our condolences to the family of the victims involved.”

The death is not being treated as suspicious and there will be a joint investigation carried out by the police and the Maritime and Coastguard Agency.
