Norwegian emergency towing service – past – present and future

Berg T. E., Selvik Ø, Jordheim O. K.

83--88

The Norwegian Coastal Administration (NCA) is an agency of the Norwegian Ministry of Transport and Communications, and is responsible for services related to maritime safety, maritime infrastructure, transport planning and efficiency, and emergency response to acute pollution and drifting vessels. NCA has five regional Vessel Traffic Service centres. Of those, Vardø VTS has the special task of monitoring high-risk maritime traffic in Norwegian territorial waters, including the sea areas around Svalbard. Based on the history of ship incidents in Norwegian waters and lack of commercial tug resources in Northern Norway and the Svalbard area, the government decided in 2005 to establish a national emergency towing service. The establishment and coordination of this service was assigned to the Norwegian Coastal Administration. This paper briefly describes the development of the Norwegian Emergency Towing Service (NETS), how the service has changed over the years and plans for the coming years. Some cases involving emergency towing vessels are described. The paper also reviews the development of a national competence plan for senior officers on vessels employed by the Norwegian Emergency Towing Service.

The data analysed in the paper are related to the hydrology of tidal waters at a tidewater glacier terminus. Set of data was collected in the wide span of time from 2009 till 2015 in the Nordaustlandet and Southwest Spitsbergen near various tidal glaciers terminus. The data are related to tidal phenomenon, calving glacier, drifting ice, hydrology of brackish water from ice of glacial origin and theirs consequences on safety of navigation. Thus, results of analysis of hydrological data may serve for improvement of safety of maritime transport in polar regions on high latitudes in vicinity of tidewater glaciers. The research work was part of the reconnaissance of hydrological and hydrographic conditions for the needs of other studies. Measurements were taken at the Kamavika inlet leading from the Hans Glacier to-wards Hornsund fjord (Southern Svalbard). Based on above data, the causes of disturbances and errors of hydrographic measurements that may occur in area of occurrence of brackish water layer and their influence on errors of digital information displayed in ECDIS systems as well as prediction of ice conditions and safety of watercrafts in vicinity of glacier terminus and on anchorage were described.
