This paper presents the unique ocean wave power station, which is composed of the floating type platform with a pair of the floats lined up at the interval of one wave length and the counter-rotating type power unit submerged in the seawater at the middle position of the platform. Such profiles make the flow velocity through the turbines two times faster than that of the traditional OWC types, and make the turbine diameter large as possible because the rotational moment hardly acts on the platform. The previous paper verified that the station is effective to get the power from the ocean wave at the normally oscillating motion. Continuously, this paper discusses the effect of the wave length on the motion of the platform and present the flow conditions around Wells type hydraulic turbine in CFD. The platform in which the floats are at the symmetrical position to the anti-node oscillates normally irrespective of the stationary wave length. On the contrary, the platform with the floats the asymmetrically arranged or being at the progressive wave plays in the dutch-roll condition and does not get the fruitful power.

Pneumatic mechanism widely used in industrial, automotive, aerospace, and etc. The principle of pneumatic like piston is move up and down due to the air pressure inside the piston. Mechanism of piston can be applied to the power plant that utilizes the ocean waves where as use of piston mechanism is very helpful in solving the problem of fossil fuel scarcity as a source of energy in power plants. In this study we will focus on the pneumatic system which utilizing ocean wave that moves longitudinally to encourage buoy that located on the piston shaft to up and down and then the pressing of air out of piston. Output of the piston will be forwarded to the generator (rotor and stator) to produce a voltage. In this paper is focused on the manufacture of pneumatic systems and processes to produce the rotation and voltage. Material of piston tube component made of aluminum and rubber, buoys made of plastic and generator such as of metal and copper coils. Output of the piston will be forwarded to the generator (rotor and stator) to produce a voltage. In this paper is focused on the manufacture of pneumatic systems and processes to obtained the rotation and voltage with aluminum for piston tube material, buoys made of plastic and magnet rotor and copper coils of stator include on the generator and get the results of ocean wave power plant using piston mechanism is 1400 rpm with a voltage of 36 volt.
