Mega Andrea is a cruiseferry owned and operated by Corsica Ferries Sardinia Ferries. She was formerly owned and operated by the Estonia-based Tallink as the MS Silja Festival, and used on their route connecting Riga, Latvia to Stockholm, Sweden. She was built in 1986 by Wärtsilä Helsinki Shipyard, Finland, for Effoa as MS Wellamo for use on Silja Line traffic. She was rebuilt in 1992 at Lloyds Werft, Bremerhaven, Germany as Silja Festival. In 2008 the ship was transferred from the Silja Line fleet to that of Tallink, but she retained her Silja-prefixed name. After being replaced by MS Isabelle on the Stockholm-Riga route in May 2013 she was chartered as an accommodation ship to Kitimat, British Columbia. She was then sold in early 2015 to Corsica Ferries. History Wellamo Following the delivery of MS Finlandia and MS Silvia Regina for Silja Line's Helsinki–Stockholm service, Johnson Line and Effoa decided to order a pair of ships based on a similar design for the Turku–Stockholm service. The first of the new ships, named MS Svea, was delivered to Johnson Line in May 1985. The ship built for Effoa was given the name MS Wellamo (after the goddess of the sea in Finnish mythology, a traditional name in Effoa fleet) and delivered in January 1986. Following delivery she was placed on the Stockholm–Mariehamn–Turku route. The Wellamo suffered her first major mishap in July of the same year when she suffered a blackout and was grounded near Mariehamn. Following the grounding she was repaired at Luonnonmaan Telakka, Naantali, Finland. In 1989 plans were made for converting the ship to a combined car/passenger/train ferry, but these were abandoned. In the summer of 1990 the Wellamo briefly served on the Helsinki–Stockholm route, because the new Silja Serenade was not yet complete, but old MS Finlandia had to be delivered to her new owners DFDS. During the same year Effoa and Johnson Line merged to form EffJohn, who now became the sole owners of Silja Line. In the early 1990s EffJohn planned a large-scale reconstruction of GTS Finnjet. However the company could not gather enough funds to realise this project. Instead the money was used to rebuild the Svea and Wellamo. In 1992, Wellamo was docked and rebuild at Lloyds Werft, Bremerhaven, Germany. Most notable exterior changes were a new skybar in front of the funnel and a new, more blue-dominated livery.
