A more sophisticated one-man vehicle is the Serbian Brodosplit R-l, which weighs 150 kg and resembles a torpedo, with the operator straddling the aluminium alloy hull behind the first of two buoyancy tanks
at NASA's Johnson Space Center to plan and train for the
In this connection, the ferry renovation and refitting comprising - Replacement of main engine, auxiliary engines, engine for bow thruster (nests delivery) : - Installation of SCR catalysts : - Removal of passenger accommodation in car decks : - Establishment of passenger accommodation in front of the car decks : - Permanent closure of bovvisir and dismantling hydraulic : - Installation of transverse bulkheads and buoyancy tank

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.
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
The technique, called off-the-bottom pulling, involved Per Aarsleff strategically fixing a combination of buoyancy tanks
and stabilizing ballasting chains to the pipe to keep it just clear of the seabed contour and free from overstressing as it is incrementally launched and pulled by a winch from one shore to the other.
This led to much speculation about how they managed to accommodate Pamela Anderson's built-in buoyancy tanks
Margaret spotted an aluminium cylinder, believed to be one of its buoyancy tanks
, while walking her rottweiler on the beach at Winterton, near Great Yarmouth.
A strong gust capsized the boat and it must have been disappoint-ing for them to find shortly afterwards that one of their buoyancy tanks
had sprung a leak.
