This document provides recommendations for good practice implementation of Modular and Crosscutting Power Take Offs (PTO) for wave energy linear direct drive technologies, in addition, a switched reluctance case study will be presented. Any wave energy technology developer or associated stakeholders should find here guidance and recommendations to consider and adopt a Modular and Cross-cutting linear direct drive PTO technology. Consensus on the core elements for Modular and Cross-cutting PTO technology is provided to enable its identification, definition and design recommendations or guidelines, including mechanical, electric, power electronics and control elements. Specifically, this CWA sets out the following: 1) Core elements for a cross-cutting and modular PTO. 2) Relevant interfaces for modular and cross-cutting PTO implementation. 3) Annex: SEA TITAN linear switched reluctance PTO.
