| Abstract | As part of the ColdTech program, the Norwegian Coastguard vessel KV Svalbard has been equipped with an inertial measurement device (MRU) to record global ship motions in six degrees of freedom during ramming of heavy ice features. The objective of the measurement campaign was to look further into the possibility of using recorded whole-ship motions to evaluate the response of the ship and the global loads acting on the hull for different types of ship-ice interactions. The system has been tested during two expeditions around the Svalbard islands and the Fram Strait in 2011 and 2012. This paper should be considered as an introduction to the measurement campaign, and discusses the authors’ views on the applicability and limitations of such a monitoring system. Although similar measurements have been carried out in earlier projects, the actual usability of the system and the potential for further development to obtain a better understanding of the ice loads and the ship response during ramming have not previously been discussed in detail. The post-processing of the recorded data and further evaluation of the global ice loads derived from the measured ship motions are discussed in brief and exemplified using the recordings from a controlled impact with a distinct ice feature. Detailed discussions and validity of results will however be presented in a separate paper. Assumptions made and uncertainties connected to the proposed procedure are also discussed. |
