Essex Fire Service was also called to the incident. They have said no one is trapped and no one is injured.
The fire service said the water was stopped by the crew:
Firefighters were sent to assist at the scene while the ship's own crew plugged the hole from inside and built a compartment with water tight doors to stem the leak as part of regular safety precautions.
The passengers and their vehicles are still on board but in no danger and the vessel will shortly be re-berthed so that they can continue their journey."
