Sea Ice Services in the Baltic Sea

TransNav : International Journal on Marine Navigation and Safety of Sea Transportation

Vol. 3, no. 4

415--420

The Baltic winter navigation depended always very much on the ice conditions in the sea. The sea ice occurs different in form and amount, depending on the sea area and the winter season. As the maritime traffic on the Baltic Sea constitutes a substantial amount in the whole of the Baltic countries transport, Sea Ice Services (SISs) have come into being. They constituted the Baltic Sea Ice Meeting (BSIM) – a body, which assembles the parties, which are interested in warnings against bad ice conditions, and in protection of navigation in ice in the Baltic Sea. An indispensable co-operator to this body was always the company “Baltic Icebreakers”. To-day within the BSIM operate by the SISs of Denmark, Sweden, Finland, Russia, Estonia, Latvia, Lithuania, Poland and Germany, Netherlands, Norway and the Baltic Icebreakers. The main statutory duties of the SISs is the acquisition, processing and dissemination of actual information on sea ice conditions and on obstructions to navigation due to sea ice. This is done by maintaining observing posts along the coast of those countries, in their ports and approaches to them, by gathering information from ships, from ice beakers, if possible – from reconnaissance flights or satellite images. Routine products of SISs are the ice reports, ice bulletins, ice charts, forecasts and warnings and other information broadcast by mass media, e.g. radio, internet, Navtex and on the national and Baltic SISs’ web sites etc.

All activities in the Arctic are conducted near the limit of technological opportunities and human abilities. But the drain of resources in the areas convenient for development obliges us to look at this severe polar region. The main objectives of the PetroArctic project (offshore and coastal technology for petroleum production and transport from arctic water) as a part of PETROMAX and MarSafe project (Marine Safety Management) are to obtain and provide information for safety of Arctic operation such as hydrocarbons production and transport from Polar seas. One of the tasks is a collection of ice pilot experiences from the people involved in the Arctic activities to learn how they felt in these conditions, how they solved difficult tasks and managed the ice. Items of special interest are connected to lost vessels and other marine accidents. Appreciable amount of written documentation and interviews have been processed and organized into a data base of marine accidents in Russian Arctic since 1900. It includes a set of maps where the locations of the accidents are shown with a description of the accidents (date, geographical environment, vessel type, what happened and how the people acted, etc). This paper includes the map for Kara Sea and descriptions of several accidents in the eastern part of Arctic as example of different situations, as well as the principles of the data base construction and accidents classification.
