| Summary: | Methods for ice model updating using a mobile sensor network Background As offshore oil- and gas production enters arctic seas, the presence of ice becomes a substantial challenge in dynamic positioning of vessels. An important part of a DP system in the arctic, is a system for doing "ice management", which likely will include the use of observer techniques including appropriate measurements for constructing an overall picture of the ice situation, and to be able to predict movement and impact of ice. Possible sensors for ice measurements include video/ radar measurements from UAVs and sensors placed on the ice by e.g. UAVs, that is, sensors that can be located based on information in an ice management observer. This project work will look at how model information can be used for “optimal ” information gathering from UAVs. The master thesis builds in part on the project work, “Measurement selection based on observability Gramians”. Work description � � Give a brief overview over the challenges with DP in ice, and how an observer scheme for ice dynamics can be help in this regard.
