Abstract: This paper aims at better understanding of the existing status and developing trends in capture and
conversion of renewable ocean energy and in use of its equipment and technology, and at promotion of the
advances in technology and multilateral collaboration. We presents a summary on the technology and
equipment in developing tidal energy, wave energy, and other renewable ocean energy in the world, based on
the 2012 international renewable ocean energy conference and the 2013 renewable ocean energy annual
conference held in China. On this basis, the common issues in the capture, conversion, and application
technology of renewable ocean energy are discussed.
