Abstract

En fremgangsmåte for å opprettholde posisjonen til en flytende installasjon som befinner seg i islagte farvann, der installasjonen særlig befinner seg i et område hvor isen kan være i bevegelse med skiftende retning. Fremgangsmåten er kjennetegnet ved at: installasjonen (1) er festet til havbunnen med forankringsliner (8) som er opplagret i installasjonens bunnparti, og der installasjonen videre omfatter et antall iskuttere (3) anordnet rundt utsiden av installasjonen og tilstøtende til installasjonens vannlinje (1) for å bryte opp havisen oppstrøms for installasjonen, hvor et antall fremdriftsorganer (4) tilhørende installasjonen (1) aktiveres for å posisjonere installasjonen med dens iskuttere (3) til og i en korrekt posisjon i forhold til den bevegelsesretning som isen (6) til enhver tid oppviser, samt at fremdriftsorganene (4) anvendes til å forflytte de oppbrukne isblokkene (14) bort fra installasjonen. Det omtales også en anordning for å kontrollere installasjonens posisjon. Oppfinnelsen vedrører også en konstruksjon av iskutter som kjennetegnes ved iskutterens holder og derved iskutterhodet kan beveges om en horisontal og en vertikal akse for å regulere dens innstilling relativt installasjonen og til et innkommende issjikt som skal brytes opp.A method of maintaining the position of a floating installation located in icy waters, where the installation is particularly located in an area where the ice may be moving in a changing direction. The method is characterized in that: the installation (1) is attached to the seabed with anchoring lines (8) which are stored in the bottom part of the installation, the installation further comprising a number of ice cutters (3) arranged around the outside of the installation and adjacent to the installation's waterline (1) for breaking up the sea ice upstream of the installation, wherein a plurality of propulsion means (4) of the installation (1) are actuated to position the installation with its ice cutters (3) to and in a correct position relative to the direction of movement of the ice (6) to any time, and that the propulsion means (4) are used to move the used blocks of ice (14) away from the installation. There is also mentioned a device for controlling the position of the installation. The invention also relates to a construction of ice cutter which is characterized by the holder of the ice cutter and thereby the head of the ice cutter can be moved about a horizontal and a vertical axis to control its setting relative to the installation and to an incoming ice layer to be broken up.
