N.E.I. designs, manufactures, sells, commissions and services the patented and Type Approved Venturi Oxygen Stripping™ (VOS™) Ballast Water Treatment System (BWTS). The VOS™ fully complies with the U.S. Coast Guard AMS program for all water types, and the imminent IMO Ballast Water Discharge Standards.

The VOS™ BWTS comes in seven (7) configurations to match the ballast water flow rates of small ships to the largest commercial vessels built, and can be custom designed or configured in parallel systems to accommodate unlimited ranges of ballast water flow rates. VOS™ System standard models include VOS-500, VOS-1000, VOS-2000, VOS-3000, VOS-4000, VOS-5000 and VOS-6000.

The VOS system is also approved to be used a standard cargo inerting device AND a BWTS simultaneously.  The “VOS-CS” system provides very low oxygen inert gas for cargo space inerting and water treatment, all controlled from a single control panel.  The VOS-CS eliminates the need for a traditional IGG, reducing operational complexity, capital costs, operational costs, training, etc…Most importantly the vessel can re-claim or save precious physical space by not installing two separate devices.  VOS can provide ultra-low oxygen inert gas to a combined ballast and cargo pump rate of up to 8,000 m3/hr.
