[4] As Oriana, she held the Golden Cockerel trophy in recognition of being the fastest ship in the P&O Cruises fleet from 1997, when she succeeded her fleetmate Canberra,[5] to her departure in 2019.

[8] She was also designed in the style of an ocean liner to facilitate long distance voyages and world cruises.

[13] In August 2019, Oriana was sold to the newly-formed Chinese cruise line Astro Ocean and renamed Piano Land.

Power is provided by four MAN B&W Diesel engines generating a total of 39,300 kW giving the ship a service speed of 24 knots (44 km/h).

P&O wanted the new Oriana to be built in the United Kingdom, but there were no longer British shipyards capable of completing such an order, so the line had to look overseas.

John McNeece and his London-based team of designers were engaged by P&O to bring the British look to the high-revenue generating interiors of the ship, such as Anderson's, Lord's Tavern, the Knightsbridge Shops, the Emporium, Harlequins, the Casino, the Photo Gallery, the Pacific Lounge, and related public spaces, as well as on-board information graphics.

Other modifications during the 2006 refit included the extension of the cricket themed 'Lord's Tavern', and refurbishment of the children's play areas.

During a 2011 refit at Blohm and Voss shipyard, Oriana's stern was remodelled and she was also converted to serve an adults only market, with the children's play areas removed and replaced with additional passenger cabins.

[17] Oriana departed on her final cruise, to Norway, the North Cape and Northern Ireland, on 23 July 2019 and returned on 9 August.

[18] In August 2019, Oriana joined the newly-formed Chinese cruise line Astro Ocean, and was renamed Piano Land.
