Gravity base structure for an offshore platform in arctic regions

摘要

A gravity base structure for an offshore platform having deck supporting columns extending from seabed to above seawater level includes bottom and top slabs having inner and outer protective walls extending between them with a lattice structure for transmitting impact energy from the outer wall to the inner wall. The deck supporting columns are substantialy free of means for transmitting impact energy from the inner and outer protective walls to them.
