Abstract

En undervanns beskyttelsesstruktur omfattende et selvbærende skall med en kontinuerlig vegg som, i installert stilling, virker til å omslutte sidene og toppen av undervannsutstyr når den er plassert over dette. Skallveggen består i det minste regionalt av veldefinerte fasetter, hvor nabofasetter er forbundet i vinkel med hverandre gjennom minst én avstivningsformasjon hvis avstivningsvirkning skyldes romforholdet mellom de vinkelmessig forbundne fasettene.An underwater protection structure comprising a self-supporting shell with a continuous wall which, in its installed position, acts to enclose the sides and top of the underwater equipment when placed over it. The shell wall consists at least regionally of well-defined facets, where neighboring facets are connected at an angle to each other through at least one stiffening formation whose stiffening effect is due to the space relationship between the angularly connected facets.
