Mighty Servant 3

From Wikipedia, the free encyclopedia

Mighty Servant 3 is a 27,000-ton semi-submersible heavy-lift ship. Its deck is 40 metres wide and 140 metres long.

The MS3 was built in 1984 for Dutch shipping firm Wijsmuller Transport, which merged in 1993 with Dock Express Shipping to become Breda-based offshore heavylifting group Dockwise Shipping B.V. Most of MS3's cargoes are oil platforms and related gear. When loading its mammoth burdens, the ship takes thousands of gallons of water into ballast tanks, sinking its cargo deck underwater. The cargo is floated into position, whereupon the MS3 will slowly pump out its ballast, lifting the deck up to sailing position.

The firm's website says such ships can "carry the heaviest semi-submersible drilling units, harsh-environment deep-water jack-up rigs and large floating production platforms like TLP's, FPU's and spars with drafts of up to 14 metres."[1]

On December 6, 2006 it sank in 62 meters of water near the port of Luanda, Angola, while offloading the drilling platform Aleutian Key. There were no casualties.[2] It was salvaged by Smit International and handed back to its owners on May 26, 2007[3]. It will be repaired and return to service.
