PRODUCTS Trojan Marinex BWTS Trojan Technologies’ Trojan Marinex ballast water treatment (BWT) product suite received United States Coast Guard (USCG) Alternate Management System (AMS) acceptance, in accordance with the USCG’s fi nal rule for Standards for Living Organisms in Ships’ Ballast Water Discharged in U.S. waters, for all water qualities: freshwater, brackish water and marine water. AMS is a temporary designation given to a ballast water treatment system ap- proved by a foreign administration. Vessels operating in U.S. waters may use an AMS-designated BWT system to manage their ballast water discharges in lieu of ballast water exchange for a period of fi ve years from a ship’s compli- ance date while that BWT treatment system undergoes USCG Type Approval testing. AMS certifi cation neither guarantees nor implies that USCG Type Approval is likely, as the two programs are independent of each other. The Trojan Marinex BWT product suite is tested and IMO Type Approved to the lowest UV transmittance value in the industry (corresponding to poor wa- ter quality) under full fl ow conditions. Testing was conducted under the su- pervision of DNV, who is certifi ed as an Independent Lab (IL) by the USCG, in accordance with United States Environmental Protection Agency (USE- PA) Environmental Technology Verifi cation (ETV) Ballast Water Protocol. www.trojanmarinex.com 70 Maritime Reporter & Engineering News • SEPTEMBER 2014 DMC Builds the Smallest Ever Nozzle Damen Marine Components (DMC), part of Damen Shipyards Group, said it smashed its propel- ler nozzle world record by 33 percent downwards. This downsizing to an inside diameter of 665 mm— from the previous 1,000 mm ‘entry level model’ – marks a new milestone for DMC’s Optima Nozzle series. Already one-third smaller than the previous one meter (1,000mm) Ben- jamins, the new 65 centimeter nozzles are, however, dwarfed altogether by the biggest models in the Optima series, with an 8m inside diameter. The two 665mm nozzles weigh 188 kilos each and were built for one 50 ft. (15m) yacht. The two mini Optimas were commissioned at Damen Ma- rine Components by a third-party manufacturer of propulsion systems. DMC’s Optima propeller nozzle combines reduced noise and vibration with propelling performance. Its specifi c inside profi le design was patented in 1998. For dredgers, Stan Tugs or inland waterway vessels, DMC’s Optima nozzles usually have an L/D 0.5 ratio (length = 0.5 x diameter). For push boats the L/D is 0.6. The two world’s smallest nozzles feature L/D 0.4 in order to still safeguard ‘crew comfort’ at the river yacht somewhat higher 11 knot speed. www.damen.com VDR Tech Danelec Marine planned to show its DM100 VDR at SMM2014. The company reports it is the fi rst VDR to be type approved and wheelmarked by BSH for compliance with the new IMO standard, which came into force July 1. The DM100 VDR features Danelec Marine’s SoftWare Advanced Protection (SWAP) technology, which stores all programming data and confi guration fi les on a hot-swappable memory card. www.danelec-marine.com New LED Light Range IMTRA announced its latest high-output LED light range, the IMTRA Sigma Pow- erLED. A straight-forward dimmable LED upgrade for existing marine halogen down light systems, the new Sigma PowerLEDs use existing fi xture locations, hole cutouts and two-wire cabling to make full-featured retrofi ts easy. The Sigma range eliminates the need to rewire existing circuits, while providing the highest level of light qual- ity and protection against interference. The Sigma series is available in small, large and surface-mounted confi gurations. www.imtra.com Photo cour tesy of Damen A member of the Edison Chouest Offshore companies, Fairweather, LLC was founded in 1976 and is today one of Alaska’s leading provid- ers of specialized support services to offshore oil and gas operations in the Arctic.
