“…Hnatiuk (1983) reports that average drilling period per year was 110 days while both drillships as well as their support systems were idle for eight or nine months due to ice conditions. A well drilled from one of the drillships could cost over $100 million and take up to three years.…”

A review of existing knowledge regarding how to manage ice during offshore work in cold waters has been carried out. The objective has been to contribute to increased safety and efficiency in future projects by learning from world-wide experiences. It was found that offshore drilling has been carried out in a wide range of ice conditions and at water depths spanning from five metres to more than a thousand metres. Icebergs in open waters have been handled safely over several years and the possibility of detecting icebergs is considered good. With respect to icebergs frozen in sea ice, both detection and deflection is considered difficult and the technology for doing so is not proven. Good ice management systems are considered to represent the main factors for operating successfully in the covered waters. Future work should focus on how to include the effect of ice management statistically in a design process.

“…Drift sea ice is a major limiting factor in regions with Arctic conditions, often restricting the operational season to a few months of the year [8]. Ice Management is the field encompassing all activities to reduce or avoid impact from ice features [4].…”

Abstract-In polar region operations, drift sea ice positioning and tracking is useful for both scientific and safety reasons. Modeling ice movements has proven difficult, not least due to the lack of information of currents and winds of high enough resolution. Thus, observations of drift ice is essential to an up-todate ice-tracking estimate.Recent years have seen the rise of Unmanned Aerial Systems (UAS) as a platform for geoobservation, and so too for the tracking of sea ice. Being a mobile platform, the research on UAS path-planning is extensive and usually involves an objective-function to minimize. For the purpose of observation however, the objective-function typically changes as observations are made along the path.Further, the general problem involves multiple UAS and -in the case of sea ice tracking -vast geographical areas.In this paper we discuss the architectural outline of a system capable of fusing data from multiple sources -UAS's and others -as well as incorporating that data for both path-planning, sea ice movement prediction and target initialization. The system contains tracking of sea ice objects, situation map logic and is expandable as discussed with path-planning capabilities for closing the loop of optimizing paths for information acquisition.
