... We introduce a semi-empirical model that can determine a ship’s performance in level ice based on Lindqvist’s model and develop a simple model for calculating ice resistance. This model assumes that contact between the ship and the ice is a case of symmetrical collision, and two contact cases...

... shell was studied experimentally. The SCS specimens were designed using the ISO ice pressure. The experimental results show that they possess far higher resistance against patch load caused by ice. Moreover, the load-deflection behavior of the curved SCS sandwich system is ductile and it can absorb...

... 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...

... of station keeping conditions for a new generation of Arctic drillrigs and production vessels. Existing scaling relationships were used to relate the resistance of the Svalbard to the expected resistance of a moored vessel of defined characteristics, and for different conditions. The paper summarizes...

The paper presents predictions of speed and power for each icebreaking tanker design, in level ice, pack ice and open water. The important features of each...

... the analysis of the resistance and propulsion tests, the Healy, with its total shaft horsepower of 30,000, was shown to be capable of its design requirement. Using a similar analysis, an imaginary “Polar 8” icebreaker of the Healy design was shown to require 85,000 HP to continuously break ice of 2.44 m (8 ft...

... The magnitude of ice loads imposed onto a structure located in land fast ice, such as an ice island, is usually controlled by the failure mechanism of the ice at the interface with the structure – crushing of the ice sheet or passive edge failure of the ice island. These ice loads are resisted...
