This paper presents a conceptual study of a wave farm based on ship-like structures being developed under the acronym KNSWING. These are attenuator Wave Energy Converters (WEC) integrating Oscillating Water Columns (OWC) with side openings in the hull. This leads to important advantages compared to solutions based on Point Absorbers as described in (K. Nielsen, 2004) such as: large modular structures with redundant PTO systems, simplicity with few moving parts, less electrical equipment on the seabed and lower grid connection costs, a main structural frame suited for mass production, high energy absorption from waves, low mooring forces, low cost concerning tow out for installation, and easy access to mechanical equipment which are all located above water.
