Catamaran sinks in River Foyle
A catamaran has sunk overnight in the River Foyle.
The MMV Ostrea was almost fully submerged on Tuesday morning in the Foyle Marina in Londonderry.
The vessel which is used by the Loughs Agency left just white railings and a blue part of the hull above the water.
A spokeswoman for the Coastguard confirmed that nobody was at risk nor required assistance as a result of the incident.
The owner of the catamaran wanted the Coastguard to be involved in order to prevent any pollution.
The coastguard did not attend the scene but measures are in place to prevent any diesel spillage.
In a statement a spokeswoman for the Loughs Agency said they are working to "investigate the cause and to float the vessell".
She said: "Just after 8am this morning the Loughs Agency were made aware that our research vessel the MMV Ostrea was partially submerged at the Foyle Marina.
"We immediately implemented our emergency response plan including the deployment of a boom, although there are currently no signs of pollution.
"All the relevant agencies have been informed and we are working with the appropriate specialists to investigate the cause and to float the vessel. "
Chief Executive at Loughs Agency John Pollock said: "Thankfully there were no crew on board at the time. We will be completing a thorough investigation to determine how this happened.
"I’d like to thank Londonderry Port and Harbour for their assistance."
