Abstract

Для поддержания воды вокруг морской установки (1), свободной от вредного воздействия льда, судно (5) используют для размещения якоря (6) в некотором месте на некотором расстоянии от морской установки (1) и в направлении, которое, если смотреть с морской установки (1), по существу параллельно направлению (Р) движения льда. Посредством механизмов судна, которые предпочтительно включают в себя азимутальные подруливающие устройства, направление якорного каната регулируют и, следовательно, регулируют ориентацию судна относительно якорного каната для того, чтобы подруливающие устройства (гребные винты) можно было использовать для измельчения льда и избавления от льда без использования энергии для удерживания судна, находящегося под действием давления льда.To keep the water around the offshore installation (1) free from the harmful effects of ice, the vessel (5) is used to place the anchor (6) in some place at some distance from the marine installation (1) and in the direction that, when viewed from the marine installation (1), essentially parallel to the direction (P) of ice movement. Through the ship's mechanisms, which preferably include azimuth thrusters, the direction of the anchor rope is adjusted and therefore adjusts the orientation of the vessel relative to the anchor cable so that thrusters (propellers) can be used to crush ice and get rid of ice without using energy for keeping the vessel under ice pressure.
