Propulsion evolves, improves and powers forward in the inland markets. And, Z-Drive propulsion is the future. In a white paper released late in 2014 by The Shearer Group, Ed Shearer and Greg Beers outlined The Next Generation of inland vessels, what will drive design changes and the advantages of azimuthing stern drives – or ‘Z-Drives,’ for short. The authors point out that, until recently, towboats on all the inland waterways and Gulf Coast have traditionally been built using main engines connected to reduction gearboxes connected to long drive shafts passing through the towboat hull. In a nutshell, according The Shearer Group, the advantages of using z-Drives on inland towboats include decreased installation time…

Enviro Voraxial Technology, Inc. has received a purchase order to deploy the underwater version of EVTN’s high volume Voraxial 4000 Separator. EVTN envisions its underwater design as the core technology for an advanced generation of skimmer vessels to facilitate the Gulf clean-up effort and to effectively protect the environment from future offshore oil spills. Other technologies that have been deployed in the Gulf followed a similar trial process. The new Underwater Voraxial oil recovery method allows the operator to separate oil from water in the ocean. By conducting the separation in the ocean, the vessels can skim oil for 10 times longer since the amount of water collected in the holding tanks is reduced by 90%.
