The design utilises some of the technologies employed in the construction of underwater vessels as the square will sit partially below sea level, and will have a system of responsive air chambers to keep it afloat - similar to the buoyancy tanks
used in submarines.
The equipment - which the company says is a "best of breed" - will be used for flooding and venting the buoyancy tanks
for the Kaombo project, located 150km off the coast of Angola.
FAO has further included built-in buoyancy tanks
and other features that ensure floatability and durability," said FAO in a statement.
Once the ship is upright, salvage teams will spend a number of months stabilising it and preparing for it to be re-floated with the aid of additional giant buoyancy tanks
before it is towed away for scrap, probably in spring.
"The pressure vessel buoyancy tanks
are a new design and required very high standards of welding and fabrication.
Riser assemblies are made of a seabed foundation, vertical pipe, buoyancy tanks
and a flexible pipe specifically configured to connect to the capture vessels.
'Thankfully they kept hold of the wreckage and waited to be rescued, which is standard capsize drill as boats have self-contained buoyancy tanks
While the standard vehicle can operate in mud and shallow water, an amphibious build option is available that includes front and side detachable buoyancy tanks
that allow the Scot-Trac to float.
