A very special vessel appeared with high-tech performance of a  360-degree revolution in place, horizontal moving, and keeping its  position automatically without being blown by wind or wave.

 Pukyong National University held a launching ceremony of ‘Naraho,’ a new  marine research vessel (Captain. Kim Jung Chang) at the reclamation  dock in Yongho-dong on the September 3rd.


 The vessel of 1,494 ton, 70.7m long and 13.5m wide is going to conduct  boarding practices for students and marine research and investigation.  It navigates at a speed of 14.3 knot maximum, accommodating 66 crew  members and trainees. The ship was built by Han Jin Heavy Industries  & Construction Co., Ltd, with investigation of 32,600,000,000 won  for 32 months from October 2012.


 The most feature of Naraho is an installation of Dynamic Positioning  System (DPS), which makes it possible for the ship to keep doing its  researching and investigation task without straying from its place by  detecting the effect of wind and wave by itself even in an extreme  situation.


 Another noticeable feature of this vessel is it has two propellers on  both sides of the back of the ship respectively unlike other ships  having one propeller only. The propellers equipped in the vessel is the  domestically first introduced Counter-Rotating Propeller, which has a  high propulsion efficiency with spiral propellers stacked each other in a  different turning direction. These enables the vessel to turn 360  degree in place or move horizontally by operating together with the  propellers in the front part of the ship.


 In addition, Naraho features a silent navigation with Electric  Propulsion System and Anti-Rolling Tank decreasing a rolling problem.


 Equipped with oceanographic observation devices such as a Multiple Echo  Sounder and a Sub-bottom Profiler, the vessel enables basic research and  practical training for marine physical, chemistry, geology,  environment, weather, and ecology areas and practical investigation for  marine resources.

 Naraho is the best vessel with the highest technology among marine  research vessels that have introduced until now, and It will be an  advance guard traveling the world ocean and advancing marine science  technology of Korea. said Kim Yeong Seup, president of Pukyong National  University.
