Mighty Servant 1

Mighty Servant 1 is a 29,000-ton heavy-lift ship capable of carrying very large vessels and offshore platforms. Built for Dutch shipping firm Wijsmuller Transport, which merged in 1993 with Dock Express Shipping to become Breda-based offshore heavy lifting group, Dockwise Shipping B.V.[3] Mighty Servant 1 carried things such as oil rigs and floating drydocks.[4] Originally 40 m (130 ft) wide, she was increased to 50 m (160 ft) around 1999 to lift the production rig P36.
