Sea Power Ltd has successfully deployed its novel ‘WEC’, or wave energy converter, prototype in Galway Bay at the SmartBay 1:4 scale test site. Their device seeks to “extract energy from ocean waves efficiently, safely and with minimum maintenance and maximum economic return”. The Platform is a wave attenuator made up of large hollow concrete pontoons that oscillate on only a single hinge. It is capable of capturing incident wave power in more than one oscillation mode which gives it a distinct performance advantage over other types of WEC devices. The simplicity of the design makes it far more cost effective than any other available attentuator-type WEC device.

Check out how the scaled prototype came together coming up to the test deployment.



Congratulations to Joe and his son Cian Murtagh for reaching this key project milestone. TfI conducted mooring simulations for this deployment and we are delighted to see it brought forward.

Team SEWEC will be spending this week testing their Floating Oscillating Water Column WEC device in the U.S Navy’s Maneuvering & Seakeeping (MASK) basin at Carderock in competition for the Wave Energy Prize. The competition sees $1.5M in prize money going to the team who can best improve wave energy converter efficiency, with the overall aim of doubling energy capture from ocean waves.

Our CTO Dr. Paul McEvoy provided his expertise to the SEWEC project in modelling of the mooring system, specifically using TfI Marine polymer mooring components. Check out this video of the scaled SEWEC generator prototype to be tested.

Sponsored by the U.S. Department of Energy (DOE), the Wave Energy Prize competition hopes to jump-start private sector innovation in the ocean energy realm, contributing to economic growth, energy security, and international competitiveness in the wave energy conversion sector.

Teams undergo a stringent application and validation process before they’re allowed near the MASK basin test facility. Current finalists would have submitted their initial design proposals between April and July 2015. Following this, an expert judging panel reviewed all submissions and selected a number of Qualified Teams to develop 1/50th-scale demonstration models of their devices for proof-of-concept testing and numerical simulation between August 2015 and January 2016. In March of this year, 10 finalists were chosen to build 1/20th scale prototypes for testing at the MASK basin facility, where the devices will be tested for performance under high-energy loading to simulate an ocean environment.

We at TfI Marine wish SEWEC and all the other finalists the best of luck in the final assessment stage, and look forward to finding out the results this November.

Great news for TfI Marine as Wave Energy Scotland have selected our Gator Power Take-Off (PTO) project to progress into stage 2 of its competitive call for novel wave energy converter devices.

Developed with our partners Exceedence, University of Strathclyde, MaREI UCC, and Pelagic Innovation, the Gator project aims to design, prototype, and test a novel polymer ‘spring pump’ capable of pumping significant quantities of water at moderate pressures through conventional hydro-electric turbines. As this innovative non-linear pump does not require any seals, it is designed for tens of million compression cycles and can be implemented in a system with very low maintenance requirements.

We at TfI Marine are delighted and excited to move forward with the Gator PTO project, and look forward to continuing work on it. Keep an eye on our website over the coming months for updates and more information on its progress.

TfI Marine will be exhibiting at Aquaculture Europe 2016 at the Edinburgh International Conference Centre (EICC), September 20-23rd. The event will see industry, academia, and government come together to discuss and exhibit on the world’s most rapidly expanding part of the livestock sector.

Noel Halloran (CEO), Dr. Paul McEvoy (CTO), and Lawrie Stove (UK manager) will be at stand 6 showcasing TfI Marine’s unique mooring solutions for offshore deployments. Stop by and chat with us about our tailored mooring tethers and how they can benefit your aquaculture farm, drastically reduce loads on your equipment, and enable deployment in high-energy sites.

The €11m FORESEA project brings together Europe’s leading ocean energy test facilities to help demonstration of tidal, wave and offshore wind energy technologies in real-sea conditions. The project is funded by the Interreg NWE (North-West Europe) programme, part of the ERDF (European Regional Development Fund).

Led by the European Marine Energy Centre (EMEC), the FORESEA (Funding Ocean Renewable Energy through Strategic European Action) project will provide funding support to ocean energy technology developers to access Europe’s world-leading ocean energy test facilities:

  • EMEC (Orkney Islands, UK)
  • SmartBay (Galway, Ireland)
  • SEM-REV (Nantes, France)
  • Tidal Testing Centre (Den Oever, Netherlands)

Commenting on the project launch, Karmenu Vella, European Commissioner for the Environment, Maritime Affairs & Fisheries said: “This programme shows the added value of European cooperation. If we are to help ocean energy on a path towards commercialisation, countries as well as companies will have to work together to overcome joint challenges. The European Commission is encouraging this kind of cooperation, for example through the Ocean Energy Forum as well as programmes such as this one.”

The first call for applicants to apply for support packages is scheduled to be announced later this month.

The EU-funded Floating Tidal Energy Commercialization (FloTEC) project is expected to advance Scotrenewables’ 2 MW floating tidal turbine technology, the SR2000, while reducing the levelized cost of energy (LCOE) of floating tidal energy.

The project will cover several aspects such as advanced standard power conversion technology as already used in offshore wind, more economical manufacturing, and integrated energy storage, according to Marco Thoma, Head of Global Marketing and Sales at ABB.

ABB is one of FloTEC project partners, led by Scotrenewables Tidal Power, in addition to other industrial and research organisations including DP Energy, Harland and Wolff Heavy Industries, the European Marine Energy Centre (EMEC), EireComposites, TfI Marine, University College Cork, and SKF.

Marco Thoma said: “One aspect that’s being looked into is to reduce costs by moving the electrical equipment, which is currently installed in the hull of the floating turbine, onshore.

“We expect that by installing the electrical equipment, such as converter and switchgear onshore, the structure of the hull can be simplified, and installation and maintenance costs can be significantly lowered. This is just one part of the project, which will deliver a number of innovations to reduce the cost of tidal energy.”

The plan is that the 2 MW prototype of the tidal turbine, the SR2000-M2, will be installed alongside Scotrenewables’ SR2000 turbine at the European Marine Energy Centre’s (EMEC) tidal test site in Orkney, where the 4 MW floating tidal array will serve as a demonstration platform for commercially viable tidal stream energy, according to ABB.

Thoma added ABB will provide engineering services and simulation studies that will focus on an optimal design of the electrical drivetrain and the connection to the grid to ensure lowest LCoE and grid code compliance.

As reported earlier, the European Commission’s research and innovation program, Horizon 2020, backed the FloTEC project with €10 million in February this year.

The European Commission’s largest research and innovation programme, Horizon2020, has awarded a grant of €10 million (£7.75m) to advance the commercialisation of Scotrenewables’ floating tidal energy technology.

The Floating Tidal Energy Commercialisation (FloTEC) project will demonstrate the potential for floating tidal systems to provide low-cost, high-value energy to the European grid mix.

Scotland’s Energy Minister, Fergus Ewing, made the announcement today [23 February 2016] in his keynote address at the International Conference on Ocean Energy (ICOE) in Edinburgh.

“I am delighted that Scotrenewables has been successful in securing €10 million from the European Commission’s Horizon 2020 programme,” commented Mr Ewing.

“Scotrenewables has proven that collaboration is a vital component in overcoming the challenges facing successful tidal energy deployment – a view echoed by the members who have joined this impressive partnership.

“The Scottish Government and our enterprise agencies have been proud supporters of Scotrenewables from the early days of the development of the SR250 prototype. Scotrenewables has taken a significant step closer to demonstrating that extracting energy from our seas can be a commercially viable, cost competitive option for producing clean, green energy.”

Following the announcement, the project partners met for the kick-off meeting.

Led by Scotrenewables, FloTEC brings together a unique partnership of the most experienced and committed commercial, industrial and research organisations involved in tidal energy today: DP Energy; Harland and Wolff Heavy Industries; the European Marine Energy Centre (EMEC); ABB Ltd; EireComposites; Technology from Ideas; University College Cork; and SKF.

The FloTEC project will advance Scotrenewables’ current 2MW floating tidal technology, the SR2000, with the development of a mark 2 turbine.

The SR2000-M2 prototype will be installed alongside the SR2000-M1 at EMEC’s tidal test site at the Fall of Warness in Orkney, forming a 4MW floating tidal array to serve as a demonstration platform for commercially viable tidal stream energy as well as optimising energy extraction for arrays in locally varying tidal resources.

There will be a significant focus on reducing the levelised cost of energy (LCoE) at every stage of the design, build and demonstration of the SR2000-M2, with significant capital and operational cost reductions expected.

James Murray, Business Development Manager at Scotrenewables Tidal Power said:

“The ambition of FloTEC is to drive down the cost of tidal energy through the delivery of a number of targeted innovations on an enhanced variant of Scotrenewables’ SR2000 floating tidal turbine. Engineering will commence in early 2016 and will include advanced power conversion hardware, low cost manufacturing technologies, load reduction mooring components and integrated energy storage.”

EMEC’s Managing Director, Neil Kermode, adds:

“Having successfully tested their 250kW prototype at EMEC since 2011, we’re extremely excited to see the next generation SR2000 take its place over the coming months.

“The performance assessment at EMEC will provide evidence of the enhancements that have been made to the SR2000-M2, de-risking the technology and improving investor confidence, supporting the technology towards commercialisation”.

The UK is almost certain to miss its EU 2020 targets for renewable energy, the National Grid has said.

The firm has produced UK future energy scenarios covering four different approaches in policy.

Even in the most environmentally minded scenario, the UK is projected to fail in its target of producing 15% of total energy from renewables.

The government no longer claims the 2020 target will be hit but a spokesman said the UK was making good progress.

The National Grid also says the UK will not achieve its own independently set long-term CO2 reduction plans unless tougher policies are imposed very soon.

Legally binding

The Climate Change Act mandates emissions cuts of 80% by 2050.

The government spokesman said the UK was still committed to the act, and last week ministers announced a world-leading interim step towards that goal.

But its advisers, the Committee on Climate Change, pointed to a huge mismatch between ministers’ aspirations and their policies.

The National Grid’s report says Britain’s progress on wind and solar-powered electricity has been quicker than some people expected.

But the rate of progress towards electric and hydrogen cars needs to almost treble (from 15 terrawatt hours (TWh) to 40TWh) to meet the EU 2020 target.

And the uptake of clean heating systems like heat pumps is also a massive challenge – needing to increase from 35 – 95 TWh.

On National Grid’s low-ambition scenario, the UK will miss the targets by nine years.

Even the greenest scenario only reaches the targets by 2022.

The renewables targets are legally binding and the EU may wish to punish nations that fail to meet them.

The UK’s energy system is closely bound to the EU in many ways, and Britain benefits from being able to import electricity through undersea cables.

It is impossible at the moment to say how links will change after the UK voted to leave the EU in the 23 June referendum.

Whatever the UK’s relationship with the EU, Britain’s energy system will still have to follow the Climate Change Act.

‘Still achievable’

The National Grid report says three technologies are needed to ensure a cost-effective path towards its goals – 22 gigawatts (GW) of nuclear, 100GW of renewables and 20GW of fossil fuel generation with carbon capture and storage technology in 2050.

A spokesman said: “The 2050 targets are still achievable, but we need much more momentum.

“The government has to change the trajectory or we are going to fail. We need to learn our lessons from where things have gone wrong so far.”

The government is struggling to build nuclear plants and scrapped a fund for carbon capture technology after Prime Minister David Cameron previously said it was “crucial” for the UK.

He later said the technology was “not working” and complained that costs had not come down as expected.

Mitsubishi Corporation is the second largest Atlantic salmon farmer in the world behind Marine Harvest, according to a ranking published in the latter’s salmon industry handbook.

Bergen, Norway-based Marine Harvest produced 407,500 metric tons of Atlantic salmon (gutted weight equivalent, or GWE) in 2015 in Norway, Scotland, Canada and Chile, according to the document. This does not include the 13,000t Marine Harvest produces in Ireland and the Faroe Islands, however, taking total production to just over 420,000t.

Aquaculture Mooring

Mitsubishi, which added Cermaq to its Chilean operation, Salmones Humboldt, in Q3 of 2014, farmed 139,000t in 2015, across its operations in Chile (60,000t, Cermaq and Humboldt combined); Norway (58,000t), and North America (21,000t). This is up from 121,000t in 2014, excluding Humboldt.

Coming in third is SalMar, with 136,400t; then Leroy Seafood Group, with 135,000t. SalMar and Leroy operate only in Norway directly, but have 50% each of Scottish Sea Farms in the UK.

In fifth is Canada’s Cooke Aquaculture, which produces 86,800t in total, with 42,000t in North America; 25,000t in Chile and 19,000t in the UK.

After Cooke comes Chile’s Empresas Aquachile, with 63,400t and Grieg Seafood, with 62,400. Grieg, which operates in Norway (31,700t), the UK (16,400t) and North America (14,300t). Next is Chilean firm Salmones Multiexport, with 51,000t.

Marine Harvest’s report only ranks firms from Norway, the UK, Chile, North America and Chile, which excludes Bakkafrost, based in the Faroe Islands. According to its annual report, Bakkafrost produced 50,565t of GWE Atlantic salmon in 2015.

In addition, the Marine Harvest list for Norway does not include Bremnes Seashore. According to Olav Svendsen, group CEO, the company had 28,000t in GWE Atlantic salmon production in 2015.

Below is the list of the world’s top salmon farmers, using the Marine Harvest report, along with the addition of Bakkafrost and Bremnes Seashore.
