Service
[
edit
]
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 14 m (46 ft).

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.

On 6 December 2006,
Mighty Servant 3
sank in 62 m (203 ft) of water near the port of
Luanda
,
Angola
, while offloading the drilling platform
Aleutian Key
.
[5]
During submerging to unload cargo, the ship developed a
list
and continued to submerge beyond design limits. There were no casualties, nor damage to the transported platform.
[6]
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
.
[7]
It was transported to Grand Bahama Shipyard for repairs, arriving on 17 June 2007.
[7]
In August 2009, after an extensive rebuild of its engines, in
Zwolle
by
Wartsila
, she was returned to service.
