DP station keeping event bulletins enhance the traditional reporting and analysis of dynamic positioning station keeping events and incidents. They ensure that the industry is provided with prompt feedback, including anonymous factual event trees of events reported to IMCA.

Individual DP events are available individually online, tagged and searchable, while the traditional PDF collections are also available for download.
