Notes[2]

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 structures such as oil rigs and floating drydocks.[4] Originally 40 m (130 ft) wide, she was increased to 50 m (160 ft) in 1999 to lift the production rig Petrobras 36 or P36.[5][6]

Service

Mighty Servant 1 can carry the heaviest semi-submersible drilling units, harsh-environment deep-water jack-up rigs and large floating production platforms like tension-leg platforms, oil platforms and spars with drafts of up to 14 m (46 ft).[7]
