The cost of scrapping the world cruise of P&O's troubled ship Aurora has risen to £26.25m, it was revealed on Tuesday.
Aurora's cancelled cruise will cost the firm £26.25m
P&O parent company Carnival originally said the cancellation of the 103-day cruise, because of propulsion problems, would cost about £22m.
The firm says that estimate has risen as the £200m Aurora will not now be used for any replacement cruises.
The ship is undergoing ten weeks of work in Germany before her next scheduled cruise begins on 22 April.
"We are playing it safe and we want to ensure that everything is okay for the next scheduled cruise," said a Carnival spokeswoman.
Aurora should have started the world cruise on 9 January but the propulsion problems meant that passengers only sailed around the Isle of Wight for the first few days.
More than 300 passengers decided to abandon the cruise before the vessel finally set sail on 19 January - only to return to Southampton after just 110 miles.
It was decided that the repair work would not allow the vessel to go at sufficient speed to complete the world cruise.
Passengers have been promised refunds and money off future cruises.
P&O Cruises managing director David Dingle said that work on Aurora was due to be completed on 19 April with the vessel expected back in Southampton on 21 April in time for her scheduled two-day cruise to Bruges in Belgium.
Mr Dingle added: "The Bruges cruise is sold out and bookings are good for the 17-day Venice cruise leaving Southampton on 24 April.
"The problems with the ship last month have not had an impact on bookings and there continues to be strong customer support for Aurora."
Aurora is being repaired by German company Lloydwerft in Bremerhaven.
