Abstract: Operational feedback and in-situ data are required to develop reliable, safe and economic designs of ships and offshore structures. The data is also a prerequisite to determine marine operation feasibility, and to study uncertainty and variability in ice modelling and engineering. This paper outlines a ship transit of the Kara Sea and details the data and observations attained during the voyage. We gain insight into the ship's ice capabilities with and without icebreaker escort by comparing observed ice conditions and ship performance against ship speed and position. The paper also presents a shipboard ice observation method which is intended to reduce biases that arise from ships avoiding thick ice in favour of leads. Our observations highlight the need for a detailed and accurate ice navigation system to enable safe and efficient navigation. It is important that this ice navigation system takes the ship performance into account when determining possible strategic and tactical routes.
