Gangway System for
Arkona Offshore Wind Farm
Vroon Offshore Services and Ampelmann have joined forces to deploy a walk-to-work (W2W) solution for the Arkona offshore wind farm in the German Baltic Sea. Vroon’s VOS Stone vessel, the newest addition to its offshore support fleet, will be mobilized with an Ampelmann A400 gangway system.
The gangway, launched in 2017, will be utilized for the first time for W2W operations during array cabling work and commissioning of the Arkona offshore wind farm. The project should finish by September.
Testing at EMEC
CorPower Ocean has successfully installed its half-scale C3 wave energy converter (WEC) at the European Marine Energy Centre (EMEC) in Orkney, Scotland.
The C3 point absorber was installed at EMEC’s Scapa Flow scale test site in collaboration with local marine contractor Green Marine (UK) Ltd. The device was towed to site and the surface-operated install sequence was successfully performed from a vessel.
The C3 WEC was connected to a floating microgrid unit provided by EMEC.
The microgrid has been designed to allow the C3 device to behave as if it were grid connected by providing a stable voltage and frequency reference, simulating the impedance of a typical grid connection, absorbing power from the device under test and providing power to auxiliary systems.
This ocean deployment is looking to prove off-grid operations to address market segments such as islands, offshore installations or remote coastal locations.
Legislation in Nova Scotia
The government of Nova Scotia has proclaimed the Marine Renewable-energy Act, a major milestone for Canada’s marine renewable energy sector.

A demonstration permitting program is now open, allowing proponents to seek up to 5 MW for demonstration of a project. The program has a cap of 10 MW and requires all applicable permits and approvals in place.
Kraken in Germany Wins
Support for Offshore Wind
Kraken Robotics Inc.’s German subsidiary, Kraken Robotik GmbH, was named a winner in the Carbon Trust’s Offshore Wind Accelerator (OWA) competition, an R&D program funded by nine leading offshore wind developers and the Scottish government to reduce the cost of offshore wind energy. Kraken Robotik was among four companies selected in the competition.
Kraken will receive hands-on mentoring and advice from the OWA industry partners, which collectively represent more than 75 percent of the European offshore wind market, as well as a potential opportunity to demonstrate its SeaVision 3D underwater laser imaging system on installed foundations at a fully operational wind farm in Europe. The aim of the competition is to help advanced technologies access the large emerging market and become part of the normal subsea inspection strategy for offshore wind developers.
AUV Docking Station for
Offshore Wind Inspection
Modus Seabed Intervention is developing an innovative approach to enable AUVs to remain at offshore wind farm sites without a support vessel. The move could shave £1.1 billion from the operating cost of Europe’s offshore wind farms and would be a world first in the sector.
Modus Seabed Intervention, in partnership with Osbit Ltd. and the Offshore Renewable Energy (ORE) Catapult, is trialing an AUV docking station to enable vehicle recharging, upload of acquired data and download of mission commands.
The use of AUVs to survey and inspect offshore wind farm subsea infrastructure is a relatively new cost-efficiency measure in this sector. In addition to the estimated £1.1 billion savings across the current 11-GW offshore wind farm fleet over the next 25 years, the scheme will also significantly reduce the need for staff to work in often hazardous environments.
The Autonomous Vehicle for the Inspection of offshore wind farm Subsea INfrastructure (AVISIoN) project has received funding from Innovate UK for further development, testing and demonstrations of Modus’s existing hybrid AUV capability and docking station. Testing will take place at ORE Catapult’s National Renewable Energy Centre in Blyth, Northumberland.

The institute will help develop and commercialize wind, wave and tidal energy technologies and help support the adoption of alternative technologies in remote coastal communities.
A $1 million investment will significantly advance the work of the green transportation research team at UVic’s Institute for Integrated Energy Systems. The funding will move forward solutions for heavy-duty marine, mining and transportation sectors working to meet their greenhouse gas reduction targets and climate change mitigation goals.
Wind Energy Economical
For Ship Propulsion
Analysis from BMT has revealed that the wingsail technology pioneered by Oceanfoil could achieve an average fuel consumption and emissions savings of 14 percent on a mid-sized tanker vessel and up to 20 percent in certain wind and sea conditions.
The results put renewable wind energy for ship propulsion in a key role as the shipping industry seeks to lower its carbon footprint and save fuel costs.
The assessment considered a system of four Oceanfoil wingsails over the course of a year on a 183-m, 50,000-tonne deadweight Panamax vessel operating in the north Atlantic. The study identifies the thrust benefits for all wind angles around the ship and uses the average to define the Oceanfoil wingsail thrust at a given ship and wind speed.
Oceanfoil is in discussions with its classification society to obtain approval for its proposed advanced all-weather camera solution to provide enhanced bridge visibility that would ensure compliance with IMO regulations.
