Mighty Servant 3 is a 27,000-ton semi-submersible heavy lift ship. Its deck is {{convert|40|by|140|m|abbr=on}}. The vessel was built in 1984 by Oshima Shipbuilding Co. Ltd. in Ōshima, Japan, 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.
Service
Most of the cargo transported by Mighty Servant 3 are oil platforms and drilling industry related gear. When loading its mammoth burdens, it takes on thousands of gallons of water into ballast tanks, which causes the cargo deck to submerge. After the cargo is floated into position, the ballast tanks are emptied with pumps, slowly lifting the deck above the waterline to sailing position.
The vessel is capable of carrying the heaviest semi-submersible drilling units, harsh-environment deep-water jack-up rigs and large floating production tension-leg platforms, semi-submersibles and spars with drafts of up to {{convert|14|m|abbr=on}}.{{cite web| url=http://www.dockwise.com| title=Exceptional Transport Management| publisher=Dockwise| accessdate=7 November 2009}}
In 2010, Mighty Servant 3 was outfitted with oil skimming equipment and used in the cleanup of the Deepwater Horizon oil spill in the Gulf of Mexico.{{cite web | title=Dockwise comes to aid of Gulf clean-up efforts | url=http://www.heavyliftpfi.com/content/NewsItem.aspx?id=1665 | work=Heavy Lift PFI | date=18 June 2010 | accessdate=2 May 2012 | url-status=dead | archiveurl=https://web.archive.org/web/20120308214915/http://www.heavyliftpfi.com/content/NewsItem.aspx?id=1665 | archivedate=8 March 2012 }}https://www.flickr.com/photos/bpamerica/4717215984/ {{Dead link|date=February 2022}}

After five months of resting on the seabed, it was salvaged by Dutch salvage-company Smit International and handed back to its owners on 26 May 2007. To pull the vessel from the seabed, the 1,200 tonne sheerleg Taklift 7 was used in combination with pumping pressurized air into the closed compartments of Mighty Servant 3.{{cite web| url=http://www.smit.com/sitefactor/page.asp?pageid=1095| title=Mighty Servant 3| publisher=Smit| accessdate=12 February 2012| url-status=dead| archiveurl=https://archive.today/20120530163449/http://www.smit.com/sitefactor/page.asp?pageid=1095| archivedate=30 May 2012}} It was transported to Grand Bahama Shipyard for repairs, arriving on 17 June 2007. In August 2009, after an extensive rebuild of its engines, in Zwolle by Wärtsilä, she was returned to service.{{cite web| url=http://ir.dockwise.com/phoenix.zhtml?c=208652&p=irol-newsArticle&ID=1318616&highlight=| title=The Mighty Servant 3 Rejoins Dockwise Fleet| publisher=Dockwise| date=7 August 2009| accessdate=31 August 2009| url-status=dead| archiveurl=https://archive.today/20120712020433/http://ir.dockwise.com/phoenix.zhtml?c=208652&p=irol-newsArticle&ID=1318616&highlight=| archivedate=12 July 2012}}
