NOVELTY - The power platform (1) has triangular platform case (2) that is configured for supporting an electricity generation device for generating electricity from water energy. The variable buoyancy is configured to sink the platform in water. The variable buoyancy is configured for floating the platform to an installation site and ballasting the platform to sit on a sea floor (200) thus providing a static support for the electricity generation device. An oscillating water column (100) is configured to generate electricity from wave energy.    USE - Offshore power platform configured to harness natural energy such as solar, wind, wave and tidal and convert energy into electrical power for use in power platform system for scour prevention skirt (claimed).    ADVANTAGE - The power platform has a barrier for minimizing erosion of the supports of the platform when the platform is submerged in water. The triangular form of the case provides inherent bottom stability so that the needs for piling or expensive foundations are avoided to support or secure the platform on the sea floor. The triangular form provides floating stability, which enables the overall structure to be floated, thus minimizing if not avoiding the costs of marine construction at sea. The platforms are located about 5 meters above the mean sea level (MSL) to minimize the wetting of the platform. The boat landing platforms are ideally located on the leeward side of each platform to provide protection and minimize exposure against the action of the primary wind and wave directions. The effect of shadowing from water movement of one oscillating water column due to the presence of another oscillating water column depending from the same platform is minimized. The positioning and repositioning of an offshore platform is made simplified and reduces the environmental impact associated with the tasks along with the installation of oscillating water column.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of assembling and installing a power platform.
