A platform assembly comprising a marine energy harvester such as a tidal turbine (70) and a frame (1). The frame (1) has a chamber (40) for containing a buoyant fluid material and serving as a buoyancy device and is adapted to convert to a ballast device during installation of the platform assembly. The chamber (40) performs a dual purpose in providing buoyancy during deployment to an installation site and providing ballast acting on the platform assembly following installation of the platform assembly at the installation site. The chamber is movable relative to a base of the frame and has guide posts (5) adapted to guide the movement of the chamber (40) relative to the base (20). The guide posts (5) can optionally be removed from the frame (1) after conversion of the chamber (40) into a ballast device. |
