Corrigendum to “State of the art of Power Take Off (PTO) systems in Wave Energy Converter (WEC)” [Ocean Eng. 335 (2025) 121669] (Ocean Engineering (2025) 335, (S0029801825013757), (10.1016/j.oceaneng.2025.121669))

The authors regret that there is a minor but important visual omission in Figs. 1, 12 and 15.

The revised Figs. 1, 12 and 15 are as follows:[Figure presented][Figure presented][Figure presented] The authors would like to apologise for any inconvenience caused.
