54 MN May 2011 PRODUCTS PropExpert 2011 Propeller Sizing Tool HydroComp PropExpert is a software tool for the sizing and analysis of propellers for work boats and pleasure craft. It provides the tools needed for the proper selection of propulsion system compo- nents: engine, gear and pro- peller. Initial development in 2011 has introduced new fea- tures for proper sizing of fold- ing propellers, with specific consideration of powering effi- ciency and cavitation limits. Notable recent purchasers of PropExpert include HS Marine Propulsion (USA), Inland Boat Works (USA), M & J Engineering (Australia), and ZF Marine (USA). www.hydrocompinc.com Army Vessels Use BriarTek Life-Saving Technology The U.S. Army has chosen BriarTek to provide the ORCA Man Overboard Indicator system for sailors aboard its Large Tug MG Winfield Scott and Logistics Support Vessel MG Robert Smalls. In the event of a man overboard situation, ORCA transmitters self-activate within three to five seconds of submer- sion in either fresh or saltwater and immediately transmit the user’s location and relative bearing to all ORCA systems within range. The ORCA system also provides the name of the individual who has fallen. www.briartek.com New Metallic LED Vaporproof Fixture Phoenix Products Company, Inc. released the Metallic LED VP Series of vaporproof fixtures. Aiming to keep the design of traditional “jelly-jar” fixtures, the Metallic LED VP uses a patent pending mod- ule to house a Bridgelux LED light source rated for 50,000 hours of illumination. These fixtures are UL 1598A listed for marine, outdoor and saltwater environments; UL 844 listed for hazardous locations; ABS listed; IP66 and LM79 tested and certified. The fixture employs thermal paste in mounting the array. www.phoenixproducts.com Environment Marine’s MSD Type II The MSD Type II Marine Sanitation Device is a biological aerobic (bacteria and air) sewage treatment system.

ZF Marine will sup- ply its 45 and 63 series trans- missions, produced in Padova, Italy to Ilmor Marine for packaging and line side shipment of the powertrain to MasterCraft’s production facility. www.zf-marine.com MTU 4000 Engines Power New LNG Terminal Tugs Boston Harbor has been a center for unloading the liq- uefied natural gas (LNG) tankers that supply natural gas to much of the Northeast. Getting those tankers safely to their terminals is the job of ship-assist tugboats such as those operated by Boston Towing and Transportation (BT&T). Suez Energy North America contracted with BT&T to handle LNG ships for the next 20 years. Based on that contract, Boston Towing was able to finance two new tugs, the 128-ft Independence and the 98.5-ft Justice. BT&T specified twin MTU 16V Series 4000 marine diesel engines for both boats, which were designed by Robert Allan Ltd. The Justice was built by Martinac Shipyards in Seattle, Wash.; the Independence was built by Derecktor Shipyards in Bridgeport, Conn. Boston-area MTU distributor, New England Detroit Diesel-Allison in Wakefield, Mass., sup- plied the engines. www.mtu-online.com Image courtesy HydroComp Image Environmental Marine Image courtesy Phoenix Products Image courtesy ZF Marine Photo courtesy MTU
