modeling, stability and hydrostatics, resistance and powering, seakeeping pre- diction and visualization, maneuvering, and structural analysis. In addition, engi- neers from the Engineering Technology Center (another division of Analysis & Technology) worked with us to provide ship signature and weapons effects analy- sis. Before any of this could happen, how- ever, Proteus worked closely with Ingalls and the U.S. Navy to obtain the required U.S. Department of State export license. Through the use of various components of the FlagShip system, Proteus was able to give a quick, accurate analysis of the proposed design to Ingalls, helping to enable the proposed concept design to meet or exceed the stringent requirements put forth by the Royal Norwegian Navy. Hullform data was taken directly out of FastShip to enable the stability, resistance and powering, seakeeping, maneuvering, and structural analyses to begin very quickly. As data came back from these analyses, changes were made to the hull- form which could then be easily re-ana- lyzed. At the same time, the geometrical model was being used to evaluate the radar cross section shaping of the ship. Because of this approach, one geometry model was used as the basis for all of these analyses, helping to avoid errors in data input, and speeding the entire process.

The Fuel Mill is a milling machine that physically alters fuel char- acteristics. When the heavy fuel is pumped through the machine's concen- tric, cone-shaped gears, it is exposed to frictional forces that shear asphaltenes as large as 70-100 microns — to approxi- mately five microns. Smaller particle size allows the fuel to pass through the purifi- er without forming sludge. The system can also be used to homogenize fuel with fresh water. Under high-temperature and pressure, the process creates a fine spray of water droplets coated with fuel. Because of the high temperature, the water will flash into gaseous states of oxygen and hydrogen, which will com- bust — and the fuel coating the water will explode into smaller droplets. The result- ing improvement in combustion allows a reduction in the excess air put into the engine for combustion — along with 78 percent nitrogen content. As a result, there will be a decrease in NOx emis- sions. Circle 199 on Reader Service Card V^X ANCHORS 1 ^ CHAINS ^ORTELBOER G.J. Wortelboer Jr. B.V. P.O.
