"Garinko-go2"is a new type Icebreaking vessel with Archimedean cylindrical screw-rotors at the bow as means for breaking ice floes, and has such features as larger Icebreaking capability as compared with conventional ones. In the ice sea, by rotating the Icebreaking rotors, spiral blades arranged around them dig into ice surfaces, and thus, their rotational motion enables the vessel to move ahead while breaking ice. This vessel can break 0.4m-thick ice floes at a speed of 2 knots, and maximum breakable ice thickness is about 0.6m<BR>Main particulars of this vessel are as follow: 150 gross tons, length overall 35m, width 7m, depth 2.7m, draft 1.9m, 1010 ps diesel engine lset, 195 passengers, and crusing speed 10 knots. Two Archimedean cylindrical screw-rotors are driven by hydraulic motors with a 500 ps diesel engine.<BR>This vessel was built in October 1996 for full-fledged commerical navigation to succeed her predecessor"Garinko-go"which had been in operation since 1987 until 1996, and then put into operation in Feburary 1997 off the Monbetsu coast in the Sea of Okhotsk to where lots of ice floes drift from Siberia.
