Abstract
The Marine Research Vessel performing the role of mothership such as marine environment protection, sea trials control, transporting equipment and personnel, maritime joint test etc. needs excellent maneuverability and propulsion performance to fulfill the given mission regardless of the rough sea state. Thus,

the Marine Research Vessel is required simulation analysis to estimate the maneuverability from the very start of the ship design and after the design it needs to be tested whether it meets the IMO maneuverability criteria and

comparison analysis on estimated maneuverability and propulsion performance.

This ship's maneuverability is estimated by using MMG equations of motion considering the effect of the mutual interference on the unique characteristics of the hull, rudder, propeller acting on the hull and accredited simulation program was used to analyze the forces and moments. In Sea trial phase after the construction Initial turning test, Turning circle test, Zig-zag test, Crash

astern test and Spiral test is conducted and comparative analysis to the simulation result is conducted to whether it satisfies the IMO maneuvering criteria.

Maneuverability that is needed for collision avoidance and altering course for maneuvering is checked by analysing on new course distance, turning performance & maneuvering indices K’ and T’.

And analysing characteristics of Inward rotation screw which is equipped in the Marine Research Vessel, suggested the chance to facilitating hull posture

and state of activation which is required for unique mission or special operations.

These results will predict the possibility and the risk of working at various sea states, contribute to efficient vessels for safe navigation, also it can be utilized

in ship design which is similar the Marine Research Vessel and estimation & evaluation for maneuverability.
