1. An offshore frame construction comprising:
structural members,
a structural joint connecting the structural members, wherein the structural joint includes a fork part, an ear part, and a pin, wherein the fork part and the ear part includes a bore, and wherein the pin is inserted into the bore, wherein:
the pin has a non-corroding surface, and wherein the non-corroding surface is:
a cladding or bushing welded or shrunk or glued or otherwise affixed to the pin which consists of a different material; or
continuous with the pin, and the pin consists of the non-corroding material; and
the bore in the fork part and the ear part includes a sliding surface, which is fitted with a liner acting as a bearing, wherein:
one or more axial bearings are inserted between the ear part and the fork part,
the bearing and the one or more axial bearings are made with a non-conducting material, and
the pin has a body, that is surrounded by the bearing and the one or more axial bearings, wherein the non-conductive material from which the bearing and the one or more axial bearings are made is selected from the group consisting of plastic, fiberglass reinforced plastic, polyether ether ketone, lignum vitae, and rubber.
