Floating structure intended for the transport and installation of a floating tensioned leg platform

A floating structure intended for the transport and installation of a floating tensioned leg platform (TLP) with a number of legs radiating from a central point, the floating structure comprises:

• controllable ballast tanks for changing its buoyancy;
• and
• a number of floating structure parts intended to be positioned horizontally adjacent each of the legs of the TLP, which floating structure parts are provided with engagement means for engaging counter engagement means provided on said legs of the TLP in such a way that, in an operative position of the floating structure in which said floating structure parts are positioned horizontally alongside the legs of the TLP, the engagement means are configured to load the counter engagement means with a downward force opposite an upward buoyancy force of the TLP to maintain the TLP at a required draft during transport and installation, and wherein said engagement means further are arranged to engage the counter engagement means in the described manner even when the legs of the TLP at least partly are positioned at a level above sea level.
