The earliest use of oscillating water columns was in whistling buoys. These buoys used the air pressure generated in the collecting chamber to power a PTO system that consisted of a whistle or foghorn. Rather than generating electricity, the PTO would generate sound, allowing the buoy to warn boats of dangerous water. J. M.
Oceanlinx technology focused on the oscillating water column principle, and developed several prototype generators which were deployed and tested in Port Kembla, New South Wales. In 2014, Oceanlinx entered receivership and its technology, intellectual property, brand and trademark were sold to Wave Power Renewables Limited in Hong Kong.

Islay LIMPET was a shoreline device using an Oscillating Water Column to drive air in and out of a pressure chamber through a Wells self-rectifying turbine. [1] [7] [8] The chamber of the LIMPET was an inclined concrete tube, with three sections each 6m by 6m.
The operation principle of MARMOK-A-5 is a point absorber OWC (Oscillating Water Column). The device is 5 m (20 ft) in diameter and a length (or height) of 42 m (140 ft), [6] with 6 m (20 ft) above the water. It has a weight of 162.2 tons. [7]
An OE Buoy or Ocean Energy Buoy is a floating wave power device that uses an Oscillating Water Column design. It is being developed by Irish company Ocean Energy Ltd., based in Cork, in collaboration with the Hydraulics and Maritime Research Centre at University College Cork, Queen's University Belfast, and Marine Institute Ireland.
It appears that this was the first oscillating water-column type of wave-energy device. [10] From 1855 to 1973 there were 340 patents filed in the UK alone. [8] Modern pursuit of wave energy was pioneered by Yoshio Masuda's 1940s experiments. [11] He tested various concepts, constructing hundreds of units used to power navigation lights.
In 2000, Wavegen became the first company in the world to connect a commercial scale wave energy device to the grid on the Scottish island of Islay. [2] The LIMPET (Land Installed Marine Powered Energy Transformer) is a shoreline device which produces power from an oscillating water column.
