Spain – Lundi 02/07/2018 – energiesdelamer.eu – PAT18, the Spanish Association of Naval Architects and Marine Engineers’ working group on Marine Renewables (ENERMAR) closed the 9th Edition of its annual Technical Sessions in Seville, Spain, on 29 June.

energiesdelamer.eu was pleased to have been a media partner of PAT18 ENERMAR. Below is a summary of what transpired during PAT18, as provided by Juan Moya Garcia, the President of PAT18 ENERMAR.


Copies of many of the interesting PAT18 working papers will in the near future be put online. energiesdelamer.eu will send to its subscribers the link once available.


During the two-day meeting, more than 60 professionals coming from industry, certification bodies, technical offices, designers, shipyards, universities environmental organizations and officials involved in the close relationship of renewable energies and marine & maritime sectors listen to and discussed with the 18 speakers and participated in 5 round-tables spanning all the aspects of this exciting new industry.


The discussions included new concepts of floating offshore wind, already installed tidal devices and pre-commercial projects and even their decommissioning phase.


First day involved two panels made up of three speeches each.

One panels addressed new concepts of floating wind and opportunities of synergies with other energy converters.

The second panel presented current Spanish companies designing and manufacturing fixed offshore wind substructures.

Finally, closing the morning session, before leaving towards Cádiz, designers, regional and national administrations, conservationist organizations and developers sat down together and discussed on the challenges, risks and opportunities of the Marine Renewables along the Andalusian coasts.

At the Puerto Real shipyard, the participants visited Iberdrola’s East Anglia One offshore wind farm’s OSS (both top and jacket), ready to sail to the site off UK shores. Beforehand, the project manager made explained how the electrical substation and structure were planned and executed.



The second day started with a panel on the maintenance of the marine plants, a key factor on their profitability and final LCOE. Several new maintenance strategies and approaches as well as a patent of an access to platforms were presented.

The fourth panel addressed “hidden” aspects of the business (although of paramount relevance): certification, installation and decommissioning.

A stunning fact disclosed here was the significant size of the decommissioning business (in a not-so-distant future….).

The fifth panel introduced wave, current and tidal devices already in prototype phase. Two of them are Spanish and one is French.

Finally, the Conference came to its end with the panel dedicated to upcoming Floating Offshore Wind solutions, in different phases oftheir TRL ascent path: From lab tests to full size prototypes.

The 18 speakers came from Spain, France, Belgium and the UK.

PAT18 made a special effort to include all the papers received and accepted, but it was physically impossible to include more than 18 speechesin only two days. The papers which were not orally presented were made available.
