Armstrong Marine, Port Angeles, WA, delivered Arctic Solution, a landing craft to transport equipment and personnel toand from oil producing regions near Prudhoe Bay, AK. Arctic Solution was built for Arctic Marine Solutions in Se- ward, Alaska, to an innovative landing craft design developed by Pat Eberhard, Engineer and owner of CoastWise Cor- poration. This new new design is co- owned by Arctic Marine Solutions and CoastWise Engineering. When laden, the 38.6 ton (85,000 lb.) vessel has a sprint speed of 30 knots (Lightship 35 knots). Itis a shallow water RoRo passenger and vehicle ferry, and features a planing hull form. It is certified to carry two crew and 49 passengers and also to carry haz-ardous materials.Because of the vessel?s size, Armstrong Marine constructed the hull and wheel-house in two sections and it is Arm- strong?s and CoastWise?s attention to detail, that makes this vessel stand out. Three removable pods were also built for the landing craft to each seat 12 workers, and can be fixed as required to the ves- sel?s deck for ferrying personnel to drilling sites. The bow ramp designed by Pat Eberhard is very impressive and can load heavy vehicles from unimproved beaches. It has the ability to sustain a65,000 lb. load for extra durability in the harsh environment of the North Slope. Lightship Arctic Solution has a payload of 28.7 tons (63,235 lb.). She is powered by triple 485 kW (650 hp) Scania DI1266M diesel engines coupled to triple Ul-traJet 410 waterjet propulsion systems, via ZF325-1 transmissions. The excep- tional maneuverability is achieved with an UltraJet JetMAster-Pro electrohy- draulic control system fitted for steering and independent operation of the three re-versing deflectors. New Exhaust Manifold V-CAT Catalyst System MIRATECH announced a successful first year demonstration of its new V-CAT Integrated Diesel Oxidation Catalyst Sys- tem on a vessel powered by two EMD 12-645 diesel engines in service in Cal-ifornia. MIRATECH, in partnership with Foss, has now completed the first year of a three-year program to demonstrateemissions reduction from the M/V BrynnFoss, using MIRATECH embedded diesel oxidation catalyst (DOC) systemsknown as V-CAT on the tug?s EMD en- gines. The V-CAT system is designed to reduce particulate matter (PM) 30-50%,hydrocarbons (HC) 50-70% and carbon monoxide (CO) 80-90% at full load con-ditions. The program was funded via a grant through the Port of Los Angeles, CA. www.miratechcorp.com 82Maritime Reporter & Engineering News FEATURE MARINE PROPULSION Landing Craft Vessel for Alaska Fitted with Triple Jets Main ParticularsBuilder: . . . . . . . . . . . . . . . . . . . . .Armstrong Marine Type: . . . . . . . . . . . . . . . . . . . . . . . . . . .Landing Craft Construction: . . . . . . . . . . . . . . . . . . . . . .Aluminium Length: . . . . . . . . . . . . . . . . . . . . . . . . .57 ft.
