# P&O Irish Sea

P&O Irish Sea was the trading name of P&O Ferries in the Irish Sea from 1998 to 2010, when it was rebranded P&O Ferries.

## History

The P&O Irish Sea brand was formed in 1998 by merging the ferry operations of Pandoro Ltd (who operated freight-orientated routes between England, Scotland and France to Ireland) into P&O European Ferries (Felixstowe) Ltd. The merged company was renamed P&O European Ferries (Irish Sea) Ltd and headquartered in the former head office of Pandoro at Copse Road in Fleetwood. Only the Cairnryan based service of P&O European Ferries (Felixstowe) Ltd transferred to the merged company.
In 1999, P&O Irish Sea announced its intention to purchase two purpose-built Ro-Pax's (roll-on, roll-off, vehicle/passenger) vessels from Mitsubishi of Japan for the Larne - Cairnryan and Liverpool – Dublin routes. This would allow the transfer of the European Leader to the Fleetwood - Larne route and sale of Pride of Rathlin. The new ships would be European Causeway and European Ambassador and were delivered in 2000 and 2001 respectively. An additional ship for the Larne - Cairnryan route was ordered in 2000 and delivered in 2002 as European Highlander.
In 2004, P&O sold its Fleetwood – Larne service to Stena Line. In addition to the service rights, European Leader, European Pioneer and European Seafarer were also sold to the Stena Sphere. At the same time, P&O announced the closure of the Mostyn – Dublin service due to low passenger numbers; this led to the sale of European Ambassador and European Envoy for further service in Europe. Originally the company had also intended to sell the Liverpool - Dublin route to Stena, but this was blocked on competition grounds. In 2005, the company withdrew from the Rosslare – Cherbourg route; this was taken over by a new company, Celtic Link Ferries, who also purchased European Diplomat. In 2014 this route was also taken over by Stena Line.
During 2006, P&O's ferry and port operations were taken over by DP World. In 2010, P&O Irish Sea, which had been run from the parent company's offices in Dover since the withdrawal from Fleetwood in 2004, was rebranded as part of P&O Ferries. Officially the company name remains as P&O European Ferries (Irish Sea) Ltd, however. This rebranding coincided with other changes within the P&O Ferries group of companies such as the closure of the Portsmouth - Bilbao route.
