Soares, C. (2016). Progress in Renewable Energies Offshore London, UK: Taylor & Francis Group.

Renewable energies offshore are becoming a significant contributor to the total energy produced in some countries and the interest in the subject is increasing worldwide. Various forms of renewable energy are being developed, from which some are at sea. There are some forms of energy that depend on the sea such as wave, tides and OTEC, which are the ones traditionally known as ocean energy but there are others like wind energy that can also be located at sea and thus be subjected to the same environmental conditions. Therefore, this conference is aimed at addressing all forms of renewable energy at sea, expanding from the concept of ocean energies. 

The first International Conference on Renewable Energies Offshore (RENEW2014) was organized at Instituto Superior Tecnico contributing to the exchange of information on the developments and experience obtained in concept development, design and operation of such devices. 

The scope of this second Conference is broad, covering all aspects of the renewable energies offshore activities such as resource assessment; wind energy; wave energy; tidal energy; ocean energy devices; multiuse platforms; PTO design; grid connection; economic assessment; installment and maintenance planning. 

The Conference aims at covering academically oriented papers, although not only from academic audiences, complementing the various existing initiatives that are associated with exhibitions of equipment both of ocean energy and of wind energy. Therefore, the papers have been subjected to a review process on the full papers and we leave here the recognition of the efforts of the various anonymous reviewers and of the Technical Programme Committee, who shared an important part of the review process. 

The final result after the review process of the 180 submitted abstracts are around 103 papers presented in 4 parallel sessions during the 3 days of the conference. The conference included also plenary presentations in the first morning with a number of invited speakers providing overviews of relevant matters in the various areas. 

The contents of the present book are organized in the main subject areas corresponding to the sessions of the Conference and within each group the papers are listed by the alphabetic order of the authors.
