A 302-metre long cargo ship has broken down on the Solent after leaving Southampton Container Terminal.
One Maneuver left berth 3-4 at 3.20pm heading to Rotterdam, but is believed to have lost power off the coast of Calshot at 3.45pm.
ABP has since confirmed the ship ran aground on Bramble Bank after losing power.
The 43-metre wide vessel dropped anchor and was assisted by three tug boats - Ayton Cross, Phenix and Lomax - and the harbour master shortly after.

"Local tug services assisted in moving her back into the main channel, she will be anchored in the Solent overnight, before her onward journey to Rotterdam."
Pictures show the boats heading towards the stricken vessel.
One Maneuver was expected to arrive in Rotterdam by 12 midday on Wednesday but the new arrival time is unknown.
An announcement was reportedly made on Red Funnel car ferries that the container ship may cause minor delays, but the Isle of Wight ferry service is now back on schedule.
One Maneuver can carry up to 79,000 tonnes of cargo each trip.
ABP has been contacted for comment.
