Abstract
A method for protecting stationary constructions, located in water and surrounded by water, against strain caused by a moving ice field in said water. A protective structure is arranged around said stationary construction. Said protective structure has a cross-section considerably greater than the cross-section of said stationary construction and it comprises, at the water surface level and below this level, an outer surface which slopes downwards in a direction against the stationary construction to form an ice breaking surface bending downwards ice, which move against said protective structure.
