To obtain a full understanding of icebreaker propulsive performance, full-scale and model experiments in ice were carried out for an icebreaker PLH "SOYA". A full-scale icetrial was made in February 1997 in the Sea of Okhotsk. A speed trial was carried out with a stopping and a bollard-pull test. Shaft thrust and torque were measured using strain gauges mounted to a propeller shaft. Thrust at zero CPP blade angle was used as its zero-level. Repeatability of the thrust measurement was examined using a bollard-pull test data. It was shown the scatter of thrust data was within 20kN. Model resistance tests in ice were carried out at the ice model basin of Ship Research Institute. The regression model for the model resistance in ice was presented. The predicted full-scale thrust was compared with the measured data and a fairly good agreement was obtained.
