Literature Survey of Station Keeping and Ice Management Available to Purchase

Station keeping of drillships in ice has emerged as a key enabling factor for offshore developments in intermediate and deep Arctic waters. A drillship would have to keep position within strict offset limits for safe operations. This requires reliable information concerning levels of ice management, estimates of ice forces, performance of mooring and Dynamic Positioning systems, and the corresponding responses of the vessels. In spite of the importance of these issues, several technical aspects remain poorly understood. This has prompted substantial recent research efforts. The objective of the present review is to provide the reader with efficient and thorough up-to-date information on available literature which deals with the various aspects of stationkeeping in ice. The review includes compilation of the literature and analysis that categorizes the investigations according to their objectives, approaches, scopes and outputs.
