A floating platform comprising a hull having a deck mounted on the upper end thereof extending above the water line and pontoons extending radially outwardly from the base of the hull, the improvement comprising temporary buoyancy means mounted on said pontoons at the distal ends thereof for maintaining the hydrostatic stability of said platform during installation.
A method of installing a floating platform, comprising the steps of:
- a) providing said platform with removable temporary buoyancy means for maintaining hydrostatic stability of said platform while ballasting down to the installation draft of said platform;
- b) towing said platform to an installation site;
- c) ballasting down said platform to an installation draft;
- d) connecting said platform to the pre-installed tendons;
- e) removing said temporary buoyancy means;
- and
- f) deballasting said platform to develop the tendon pre-tension required to provide stability to said platform.
