Insights in icebreaker assistance operations for different ice conditions are obtained. Winter is a complex but common operation in the Northern Baltic Sea areas.
In Finnish waters, the safety of the wintertime maritime transportation system is managed through the Finnish—Swedish winter system. This system in different operational modes of shipwith vessels either navigating independently or under icebreaker assistance. A recent risk analysis indicates that during icebreaker assistance, convoys operations are among the most hazardous, with convoy collisions the most important risk events.
While the accident likelihood per exposure time is rather low, accidents occur almost every winter. Even though these typically lead to less serious consequences, accidents leading to ship loss and oil pollution have occurred and may occur in the future. One aspect of ship convoy in ice conditions is the distance kept between the icebreaker and the ships in the convoy, a form of the well-known ship domain concept.
While operational experience naturally is a valuable source of information for decision making about the distance of in convoys, systematic analyses are lacking. The aim of this paper is to investigate selected operational aspects of convoy in ice conditions in the Finnish waters of the Gulf of Finland, based on data of the Automatic Identification System and sea ice hindcast data.
Focus is on obtaining qualitative and quantitative knowledge concerning distances between vessels in escort and convoy operations and the respective transit speeds, conditional to ice conditions. Such empirical knowledge can support operational decision making, contributing to wintertime maritime safety.
