Marine energy specifically represents, among energies available in the natural world, energy created by power over the sea, on the sea, or under the sea, such as “wind power on the sea,” “power created by vertical movement of waves,” and “power created by tidal flows.”
Waters off the coast of Kabeshima Island in Karatsu City are located in the Genkainada Sea, northwest of Saga Prefecture.
It is roughly about 129° 52’ east longitude and 33° 34’ north latitude.

The demonstration field is an area of water where the performance or durability of power generator using marine energy is tested in actual experiments. Experiments are conducted to test whether a machine developed to tap energy from wind on the sea or tidal flows can produce energy efficiently. Now that an era of producing energy from the sea is expected to come, the outcome of visiting this experiment station will lead you to a step into such a future.

It is necessary to go through the procedures according to Saga Prefecture Demonstration Field Guideline (hereinafter the Guideline. See * for details.).

Please contact the Secretariat when you intend to use it.

* Established by the council organized by Saga Prefecture as a demonstration field operation and management guide , this Guideline is a compilation of local rules and use procedures intended to ensure the smooth use of the demonstration field, commercialize marine recyclable energy, and realize revitalization of local community, including coexistence with fishery and creation of new industries .

Demonstration Field This section explains the location of the demonstration field, water areas available for use, surrounding natural conditions, and an overview of social conditions.
Use Conditions This section provides conditions for use of the demonstration field.
Consideration of Local Community This section specifies things to be considered of the local community to ensure the smooth use of the field in harmony with local community.
Necessity of Safety Measures It presents an outline and procedures of safety measures to be taken for appropriate use of the waters.
Outline of the Service and Fees This section explains the services to be provided, the fee system for the services, and the period of use.
Response to Study Tours It explains how study tours are received.
Contact It explains the contacts for each activity.
Procedure of Application for Use It shows the process of application.
History of Guideline Development It outlines the history behind development of the Guideline.
We have a set of various services that supports business operators. Here are some of the examples.

  • The remote monitoring system is in place. It allows the office staff to see the condition of the demonstration field, its surrounding waters, and the demonstration equipment.
  • We monitor various meteorological and hydrographic data, including the wind conditions, waves, or tidal flows of the waters on a daily basis during the test period.
    Our observation equipment has the following specifications.
Name Seawatch Wind Lidar Buoy
Size 2.8 m in diameter, 6.3 m in total height,
2.8 m in height from the sea surface, and 1.6 ton in weight
Measurement Data Wind velocity (12.5 m to 300 m in altitude), wind direction, wave height,
wave cycle, wave direction, flow rate, flow direction
Characteristics (1) Certification of DNV-GL, Norway, measured wind condition, data precision obtained
(2) Japan’s first buoy equipped with Doppler lidar function (*Reference)
* A function that measures wind velocity by emitting laser light to the air, receiving the reflection of light that returned off from dust or minute particles in the air, and measuring the moving speed.
(3) It is capable of making an independent measurement and transmitting data.
(4) It is easy to relocate or withdraw.
(5) It is less costly than a wind condition observation tower.

  •  We have mooring chains and anchors used to locate test equipment in the demonstration field.

  •  
  • * Even through the field is shown to be available, the use procedure
     by other organization may be ongoing.
