P&O took delivery of the ship in October 2007 from Acciona Trasmediterránea. She was the second P&O ship to have carried the name European Endeavour.
The ship was built in 2000 for Merchant Ferries as Midnight Merchant for a planned service between Liverpool and Belfast, however, the ship was chartered to Norfolkline for their new service between Dover and Dunkirk and remained on that route until July 2006 when she was replaced by Maersk Dover, a newbuild.[1]
In August 2006, she was chartered to Acciona Trasmediterránea for service in the Mediterranean and renamed El Greco registered under the Spanish flag.
On 26 June 2007, it was announced that P&O Ferries had agreed to purchase the ship in order to meet the growing demand for space from haulage customers throughout its operations. The ship will primarily be used on the Dover - Calais route but also on P&O Ferries Irish Sea and North Sea routes to cover for the refit of other vessels.[2] The ship entered service with P&O on their Liverpool-Dublin route on 6 November 2007.
The ship has been involved in two incidents. On 22 March 2008, the ships mooring ropes parted resulting is her drifting across the eastern entrance of Dover Harbour. The ship was assisted back to her berth by a Dover Harbour tug.[3] On 29 August 2008, the ship suffered a partial loss of electrical power, which resulted in a collision with Linkspan 7 in Calais. European Endeavours 'cow catcher', a metal structure welded to the bow to support the bow ramp when deployed, was demolished and significant damage was caused to the linkspan.[4]
Due to a downturn in freight traffic P&O Ferries laid up the ship in Tilbury in May 2010. She was chartered to DFDS Seaways in August 2010 and early September 2010 to provide refit cover on the Birkenhead - Dublin and Belfast routes. On completion of this charter the ship was sent for its annual overhaul and then proceeded to Dunkerque for layup. She remained in Dunkerque until early February 2011, when she sailed for Liverpool in preparation for returning to service on the Liverpool-Dublin service replacing the M/V Norcape.
In May 2019, P&O sold European Endeavour to Eckerö Line.[5] She is to act as a complement to Eckerö's current vessel the Finlandia on the Helsinki to Tallinn Route commencing in June berthing at Vuosaari on the outskirts of Helsinki. She will join the service following another dry docking with an increased capacity of 366 passengers. She only left the dry dock at Cammell Laird on 2 May 2019, in what looks like the last dry dock visit as a P&O vessel.[6]
It was P&O's intention that the ship would primarily be used between Dover and Calais but would also cover the refits of other ships on the following routes:-
It was discovered that the ship was too wide to fit through the lock at Hull so she did not serve the routes from that port as intended. She was briefly used on a re-established Dover-Zeebrugge route but the service only lasted for one day due to lack of freight.
