High Stability and Scalability


High Stability & Reliability

INWave controls the torque of the generator according to a specific magnitude of the wave energy in order to maximize recovery. This allows controlling of the movement of the buoy against the waves, the tension of the rope and the amount of wave energy recovered.

This technique, by limiting the amount of energy recovered rather than forcing it to withstand, provides flexibility in dealing with unusually high waves and harsh marine environment caused by occasional typhoon.


High Stability & Reliability

INWave Onshore improves overall durability and provides better conditions for installation and maintenance by placing main power generating devices on land thus minimizing exposure to seawater waves.

Furthermore, it increases overall reliability by utilizing proven, off-the-shelf, industrial components such as permanent magnet synchronous generator (PMSG).


High Flexibility and Expandability

INWave’s modular configuration provides flexibility in terms of total power generation capacity by simply adjusting the number of installations subject to site conditions and power demand.

One buoy (EAU – Energy Absorbing Unit) and one on land installation comprise one full set of INWave Onshore model with a capacity of up to 350kW.

One MW-capacity may be reached by configuration of three sets of EAU and on land installations, which would require a strip of space on water and land with an area of approximately 100m x 100m.

Easy Transportation and Installation

INWave Onshore’s main power converting, generating and control units can fit in a freight container-type enclosure for ease of transportation.  Upon delivery to a designated site it can be easily mounted at the site by crane.  For mooring and controlling of buoys, subsea pulleys are installed and secured on underwater concrete blocks or piles depending on terrain conditions of the site.

Buoys are designed and constructed either in an all-in-one or detachable form for ease of transportation.  When buoys are placed on the water, they can be transported by a tugboat.  Installation of buoys (Energy Absorbing Unit) is completed when ropes are connected/attached thereto.

Since the ropes perform the function of power transmission and mooring, no additional devices or underwater transmission cables are required.
