... tests will be carried out in order to improve their ice-going capability as well as their performance. This in turn leads to increased demand for physical model testing in ice to assist a design process and to improve a vessel’s ice-going capability and performance. The estimation of a ship’s resistance...

... The first resistance and propulsion tests of a Terry Fox model were carried out in 1988 at the Institute for Ocean Technology, IOT (formerly Institute of Marine Dynamics, IMD). More recent resistance and propulsion model tests were again conducted in 2007. This paper describes not only...

... by experimentally investigating the hull’s ice transiting resistance and its motions, and to validate a numerical model of lifeboat sail away. This paper reports on the physical model experiments and their comparison with numerical modeling. model test concentration thickness 10th concentration simulation...

... Propulsion model test results of the USCGC Healy are reported here and correlated with full-scale data. The design requirement for the Healy was for “continuous icebreaking at 3 knots through 4.5 ft (1.37 m) of ice of 100 psi (690 kPa) strength”. The full-scale trials were designed to test...

... is benchmarked against measurements from PMM model tests. A preliminary parametric analysis on the channel width and yaw moment due to the ship motions is carried out using the model. The simulation results demonstrate the capability of the model for the real-time simulations. model test ship ice piece...

... The current tendency shows that ship designers prefer to apply advanced methodologies, such as direct calculation and model test, to rationalize the propulsion system and propeller design. In this paper, two critical design issues for ice ship propulsion, namely engine powering and propeller...
