PlanetSolar Stops in Morocco to Promote Renewable Energy
Having departed from Boulogne-sur-Mer, France, on May 25, the PlanetSolar solar vessel arrived in Atalayoun in the Marchica lagoon, Morocco, in June. The ship’s arrival to this location shows the Moroccan authorities’ desire to promote the use of renewable energies within the framework of a comprehensive development plan for the Marchica lagoon. Over the course of a week, the catamaran served as the central hub for events that were meant to showcase the progress of this large project.

The stopover was also an opportunity for PlanetSolar to announce a partnership with the agency in charge of the site’s development, MarchicaMed. PlanetSolar will manage a pilot project that aims to power the Marchica harbor master’s office completely autonomously and without carbon dioxide emissions. MarchicaMed also aims to use a fleet of electrosolar boats for lagoon transportation.

The catamaran stopped in Morocco for about two weeks, then sailed to Monaco for a solar boat race. Afterwards, the ship was to sail to Greek waters to be a scientific platform for the University of Geneva to study submerged prehistoric landscapes during the TerraSubmersa expedition.


OpenHydro, EDF to Test Two Tidal Turbines in France
OpenHydro (Dublin, Ireland) will supply two new tidal turbines for installation at Paimpol-Bréhat in Brittany, France. OpenHydro and Electricité de France (EDF) are going to test the turbines operation in connection to the grid. The turbines will be operational from 2015. This pilot phase will pave the way for the deployment from 2016 of precommercial farms and the development of a tidal energy industrial sector in France.

The new project builds on the successful testing of the tidal turbine L’Arcouest in real conditions between December 2013 and April 2014 at the Paimpol-Bréhat site. These conclusive tests demonstrated the performance of the tidal turbine developed by OpenHydro and also served to validate the principle of the 16-meter-diameter prototype.

The second-generation turbines will be adapted for series production to support future calls for tenders for commercial farms. The development of the Paimpol-Bréhat pilot farm, together with other pilot farm projects OpenHydro is progressing in France and Canada, are intended to demonstrate the technical, economic and environmental feasibility of the tidal energy sector.


BOEM Issues Lease to FAU for Turbine Testing in Florida
BOEM has issued a lease to Florida Atlantic University (FAU) for marine hydrokinetic technology testing offshore Florida to evaluate the use of turbines powered by ocean currents. This is the first time a lease has been issued to test ocean current energy equipment in federal waters.

FAU’s Southeast National Marine Renewable Energy Center applied for a lease to deploy experimental demonstration devices in an area located approximately 10 to 12 nautical miles offshore Fort Lauderdale.

The proposed project involves the installation of multiple anchored, floating test berths to evaluate ocean current turbine designs. Each test berth will consist of a buoy anchored to the seafloor to measure ocean conditions and allow ocean current turbine prototypes to be deployed from vessels moored in the Gulf Stream. Now that the lease has been executed, FAU may submit a project plan for BOEM’s review.


FoundOcean Tests MGPs at UK Offshore Wind Farm
FoundOcean (Marlow, England) is testing its latest range of Marine Growth Prevention (MGP) units on an unnamed offshore wind farm jacket structure in the U.K. Two units have been installed in the Liverpool Bay area. These latest units are the beginning of an extended trial period on the jacket, following successful results of an earlier version of an MGP unit fitted in 2013.

As well as adding to the static weight of a structure, marine growth can interfere with the systems for corrosion protection and increase the hydrodynamic loadings associated with wave and current actions on the structure.

These increased stresses can result in unnecessary and avoidable fatigue damage that can reduce the operational lifespan of the asset. Hence, many offshore standards address the control of marine growth, particularly with regard to the inspection of marine growth buildup and its removal.

MGPs constantly prevent the buildup of the microbial slime, which is the precursor to much more damaging hard and soft marine growths like crustaceans and seaweed.

MGP is offered in two versions: wave-driven for splash zone applications and current-driven for controlling marine growth subsea.

By eliminating the need for divers to periodically remove marine growth, numerous asset managers around the globe have found that the technology is one of the most cost-effective and safest life extension solutions on the market.


DNV GL Proposes New Enhanced Oil Recovery Concept
DNV GL (Høvik, Norway) is proposing a new concept that combines mature water injection technology with the newest developments in offshore wind power to achieve more cost-effective enhanced oil recovery (EOR). DNV GL’s concept intends to integrate the compressor and water treatment equipment into the substructure of a floating wind turbine.

DNV GL studies show clear indications that such a wind-powered water injection system could reduce both capex and opex and drive innovation of new technology. It could be installed without costly retrofittings on the platform, provide access to systems normally located subsea, increase the flexibility of injection location and reduce installation time. The system would also be easy to move and use at new locations after the closure of a well or field.

DNV GL invites industries to develop this concept further in a joint industry project.

Studies show it will reduce the cost of water injection, avoid costly topside modifications and reduce greenhouse gas emissions.
