Abstract: An observation platform device, including a platform deck, an observation mechanism disposed on the platform deck, a primary swing reduction and self-righting mechanism, and a secondary swing reduction mechanism. The primary swing reduction and self-righting mechanism includes a hollow upper support rod, a solid lower support rod, a buoyant cabin, and a counter weight cabin. The lower support rod includes a lower end fixedly connected to the counter weight cabin, and an upper end fixedly connected to the buoyant cabin. The secondary swing reduction mechanism includes a water pond, a plurality of wing-type supports, and a plurality of spaced fan-shaped floating cabins. The plurality of wing-type supports each includes an upper end fixedly connected to a lower plane of the platform deck, and a lower end fixedly connected to an upper plane of the fan-shaped floating cabins.

Abstract: An underwater operation platform, including: a main body; two ducted propellers disposed at the tail end of the main body; a living building; pile legs; a tower crane; a submergence module; lifting devices; and a gantry crane. The main body includes a deck and a moonpool. The submergence module includes a support plate, a plurality of truss members, and a base plate. The living building disposed on the front end of the deck. The pile legs are disposed at the four corners of the main body, respectively. The deck includes two parallel pathways which are located at two sides of the moonpool, respectively, for supporting the gantry crane. The lifting devices are disposed on the deck and are close to four corners of the moonpool. The support plate and the base plate are integrated with the plurality of truss members.
