Mastkonstruksjon og fremgangsmåte for oppreisning av samme, på en offshore-installasjon

摘要

Mast construction for an installation to be installed floating on water. On part of the mast construction extends beneath the water level and one part, provided with the installation, extends above the water level. The part close to the surface of the water (4) has a smaller effective circumference in order to limit the effect of striking waves as much as possible. Tensioning cables (15) can optionally be present at the location of the part having the smaller effective circumference, so that the strength remains optimum.
