Abstract

A steel lattice tower structure for supporting minimum offshore facilities, which is formed by two parts twisted 45 deg with respect to each other, the upper and lower parts having respectively vertical and battered legs, connected to each other by a transition truss located approximately 40% down of the water depth. The present invention also includes a procedure for fabricating and installing the entire structure as two separate units assembled offshore.
