The Centre for Ocean Energy Research (COER) at Maynooth University Ireland hosted its 5th workshop event on Friday 20th January 2017, sponsored by Science Foundation Ireland. The scope of the workshop covered a range of topics across wave energy conversion, with a broad focus on modelling, control and
estimation/forecasting.

The workshop featured 11 oral presentations from invited experts, from both industry and academia, including the renowned Prof. Johannes Falnes (NTNU). Additionally, 26 posters were presented at the event, providing a catalyst for conversation and networking between the 90+ attendees during the coffee and lunch breaks. The workshop concluded with an open forum discussion, on the topic "Instabilities of WECs: Good news or bad news?", chaired by Alain Clement.
