Full-scale ship trials at actual seas are carried out using a training ship Seiun-maru. The training ship is equipped with a data processing system using local area network with which many kinds of data such as ship speed, rudder angle, propeller revolution, wind, current, and waves etc. can be collected and stored as a set of data file easily. Collected data are analyzed from viewpoints of ship manoeuvrability under external forces, long-term ship propulsion performance quality, crews work efficiency and comfortableness and maneouvring motion in harbor. On manoeuvring motion under external forces, validity of wind and current data are confirmed and manoeuvring motion in wind and current can be estimated by simulation under consideration of the effects of these external forces. On long-term ship performance quality, relations between external effects and propulsive quality are demonstrated by analysis of long-term global voyage data. Moreover, present evaluation procedure for long-tem ship performance quality introduced by authors is confirmed to be effective and new estimation technique is also proposed. On crews work efficiency and comfortableness, subjective evaluation is carried out through questionnaires. The results of questionnaire are compared with measured acceleration data and relations between them are investigated. On manoeuvring motion in harbor, simulation model used in this paper is confirmed to be effective to estimate the motion in harbor. All reported here in this paper indicate that data collected through the training ships information processing system using local area network is very useful and effective for researches on operational performances of ships at actual seas.
