Archaeologists in Newfoundland are planning a survey of a wrecked ship which has recently washed up on the coast and may be up to 200 years old.

As the BBC reports, the 24 metre-long shipwreck was found by a boy hunting sea ducks near the shore outside Cape Ray, a coastal town in south-west Newfoundland.

There is speculation that the wreck, which would have been one of many caught by the large shallow rocks off Cape Ray, could have been dislodged from the seabed well over a year by Hurricane Fiona.

The hurricane hit Canada in September 2022, having travelled north from the Caribbean and through the Atlantic.

Wanda Blackmore, whose son found what seemed at first like "a dark object out in the water", told the BBC that it “could be the ship that brought my ancestors, or my husband's ancestors”,

Like many Newfoundland residents, she has English, Irish and Scottish roots, linked to the seasonal Atlantic cod fishery.

The archaeological team has to survey the timbers before strong waves pull the ship away from the coast and towards deeper waters.

Neil Burgess, president of the Shipwreck Preservation Society of Newfoundland and Labrador, said it was hoped to “be able to piece together where this ship came from and how it ended up here”,

A diving team based in Fermoy have captured up-close images of a shipwreck that lay undiscovered in Bantry Bay for nearly 200 years.

The French naval frigate La Surveillante was deliberately scuttled by its captain in 1796 during the failed landing that proceeded the 1798 Irish rebellion against British rule.

It was not seen again until 1979 during clean-up operations that followed the Whiddy Island tanker disaster.

Blackwater Sub Aqua Club member Timmy Carey told The Corkman that he and his fellow divers had wanted to visit the wreck of La Surveillante for more than 20 years.

“During the dive we saw numerous cannons, timber pulley blocks from the rigging, its anchors, cooking utensils, the high raised bow and even piles of small musket balls,” he said.

“We also saw the long sheets of copper plating that had been nailed to the outside of the timber hull for protection.”

The world’s deepest shipwreck on record has been found by a team of explorers in the Philippine Sea.

The hull of the USS Samuel B Roberts, or Sammy B as it was known, was located at 22,916 feet (6984.7 metres) by a team involving explorer, private equity investor and former navy commanader Victor Vescovo of Caladan Oceanic Expeditions and British exploration company EYOS Expeditions.

Most of the world’s ocean floor is less than 6,000 metres deep, and areas deeper than that have tended to be linked to great tectonic trenches.

The Sammy B was one of several ships named after US Navy coxswain Samuel Booker Roberts, Jr., who died in the second world war Battle of Guadalcanal in 1942.

Roberts was part of a rescue mission for a company that had been surrounded by Japanese forces. He steered his vessel directly into the Japanese line of fire, and was mortally wounded.

The Sammy B, a destroyer, was commissioned in 1944 and was sunk by Japanese forces during the Battle of Samar later that same year. Two other US Navy ships were also later named the U.S.S. Samuel B. Roberts.

The Sammy B is reported to have damaged the Japanese fleet and delayed it for so long that it retreated, but the destroyer sank after it was hit with the loss of 89 lives. Some 120 crew on board were saved, after clinging to the wreckage for up to 50 hours according to BBC News.

“The Sammy B bore evidence of the incredible, ferocious fight that she waged against the cream of the Imperial Japanese Navy,” Vescovo told Jonathan Amos of BBC News.

“There were shell holes. She obviously had taken a massive hit from a battleship on her stern quarter [the rear of the boat], with it basically blown apart.”

Vescovo said that he was surprised they were able to find the ship because there was so little debris. It was broken in two, but he said it was relatively intact.

“Using a combination of detective work and innovative technology, everyone has pulled together to reveal the final resting place of this tenacious ship,” Kelvin Murray, EYOS expedition leader and director of expedition operations and undersea projects, said in a statement.

“It’s been challenging, thrilling and poignant expedition, one that recognises the ships and sailors from all nations who fought so hard during this battle.”

The same team discovered the U.S.S. Johnston last year in the Philippine Sea at over 21,000 feet – which then held the deepest wreck record until identification of the Sammy B.

Mr Vescovo was the first person to visit the deepest points in Earth's five oceans.

He's also climbed the highest peaks on each of the seven continents; and he recently went into space on New Shepard, the rocket and capsule system developed by Amazon.com founder Jeff Bezos.

Norwegian divers have discovered a 300-year-old shipwreck of an Irish sailing ship on the sea bottom outside Mandal in Southern Norway.

The Irish ship, named "The Providentz", sunk in November 1720.

It is reported by the Norwegian NRK journalist, Siv Kristin Sællmann, that all crew members were saved, but the ship was left at the sea bottom. Divers and archaeologists are astonished by how well-preserved the ship and its possessions are.

The ship and most of the possessions will be left on the sea bottom for divers to explore freely.

The National Monuments Service says it has resolved the mystery of a shipwreck off Co Sligo's Streedagh strand where three Armada ships are known to have foundered in 1588.

Research has confirmed that a wreck of a vessel off Streedagh known as "the Butter Boat" was a Yorkshire coastal trading ship, the Greyhound.

The ship from Whitby port sank with the loss of 20 lives on December 12th, 1770 - some 182 years after the Armada fleet.

The National Monuments Service, which marked the 250th anniversary with the local community last week, says that the Greyhound tried unsuccessfully to seek shelter in Mayo's Broadhaven Bay during a storm in December 1770.

It anchored off Erris Head in Co Mayo, but the crew was forced to abandon ship, leaving a cabin boy on board.

The National Monuments Service says that "on learning of the plight of the cabin boy, local volunteers from Broadhaven Bay, together with the crew of a passing ship from Galway and some of the original crew of the Greyhound showed extraordinary bravery in an attempt to rescue the boy and the stricken ship".

"While the rescue team did manage to board the Greyhound and move the vessel away from the cliffs, it was driven further out to sea by the force of the storm with some of the volunteer crew still on board, including the cabin boy, and later that night she was wrecked at Streedagh Strand, 100km to the east, with the loss of 20 lives," it says.

Oak timbers from the wreck were recorded and analysed by Denmark-based dendrochronologist Dr Aoife Daly as part of the research, which also included liaison with the Irish Folklore Commission’s Schools Manuscripts Collection, archived in University College Dublin.

An account given in 1937 by a Streedagh local, 75 year-old Michael MacGowan, to his granddaughter, told of a ship, described as a “tourist boat”, driven ashore at Streedagh Point some 200 years previously.

Mr MacGowan said all the crew bar one attempted to clamber to safety over the rocks at Streedagh Point but were drowned after falling into a deep recess between the rocks.

Later that night the ship re-floated on the rising tide and was washed ashore on the beach at Streedagh, where it grounded in the soft sands and is the vessel still visible today known as the “Butter Boat”, he said.

When the tide receded the following day, the one man who remained on the boat, Mr Williams, made it to the safety of the shore and, according to Mr MacGowan’s account, he returned "home" to England..

Dating sequences obtained from two samples had placed the construction of the vessel firmly in the first half of the 18th century, sometime after 1712, the National Monuments Service said.

"The analysis also indicated that the timber used in the construction was probably sourced from the English midlands or possibly Yorkshire,"it said.

" This provenance of the ship's timbers along with the 18th-century dendro date, clearly rules out any association between the ‘Butter Boat’ and the 16th century Spanish Armada campaign," it says.

Minister of State for Heritage at the Department of Housing, Local Government and Heritage, Malcolm Noonan welcomed the work put into confirming the events leading to the ship's loss.

“I know there is a huge amount of local interest in this wreck and that its identity has been a topic of debate for many years, with many calling it the Butter Boat and others thinking it part of the Armada, "Mr Noonan said.

He said he was struck in particular by "the value of folklore archives along with applied archaeological research in uncovering the full and tragic story of the Greyhound and those caught up in the tragedy’’.

“Its calamitous story illustrates starkly the perils of the sea but also highlights, how in times of trouble, the common bond of the sea brings people from different backgrounds together in an attempt to save lives," he said.

" I am proud that my department has been able to bring to light this story of tragedy and loss but also of extraordinary bravery, compassion, selflessness and heroism,"he said.

The commemoration with a wreath-laying at the wreck at Streedagh Strand on December 12th involved local residents, religious leaders and members of the National Monuments Service team.

"I am very appreciative of the continued community partnership between my our National Monuments Service and the Grange Armada and Development Association, Spanish Armada Ireland and Sligo Sub Aqua Club to promote, commemorate and keep watch over the internationally important wrecks of the Spanish Armada lost at Streedagh in 1588 and also the wreck that we now know is the remains of the Greyhound, "Mr Noonan said. 

"We hold in our honoured custodianship the memory of those lost in the Spanish Armada wrecks and to that, we now add the memory of those lost in the tragic wrecking of the Greyhound 250 years ago," he added.

The annual INFOMAR Seminar is a celebration of the year’s work by Ireland’s national seabed mapping programme. INFOMAR is funded by the Department of Communications, Climate Action and Environment and is jointly managed and operated by Geological Survey Ireland and the Marine Institute.

Attendees at the seminar, which will be held in Dingle, Co Kerry, on 16 and 17 October, will be among the first to see details of more than 8,500 of seafloor mapped, over 20 shipwrecks surveyed, and new 3D visuals of the coastal landscapes developed during the 2019 survey season.

The event will focus on Irish seabed mapping activities related to marine science, biodiversity, heritage and tourism in coastal communities. The event will feature an exciting line-up of experts presenting on; shipwreck mapping and archaeology, ocean literacy, marine ecology, ocean energy and infrastructure, as well as submerged and coastal landscapes and the connection between marine tourism and Fáilte Ireland’s Wild Atlantic Way.

Koen Verbruggen, Director of Geological Survey Ireland stated; “The INFOMAR seabed mapping programme continues to create significant positive impact at national, European and international levels, however this year’s annual conference in Dingle, Co Kerry, reflects INFOMAR’s prioritisation of engagement with local maritime communities who remain key stakeholders in Ireland’s national seabed mapping programme.”

“Ireland is an exemplar internationally in demonstrating best practice in ocean governance, through mapping, observing, predicting and managing our marine territory and resources. Connecting society with the value and importance of our ocean wealth is critical if we are to address today’s challenges, including climate change and population growth” said Dr. Peter Heffernan, CEO, Marine Institute.

Minister Canney stated; “INFOMAR, Ireland’s internationally renowned seabed mapping programme is an impressive example of inter-agency cooperation within the Government of Ireland. By holding its annual seminar event in Dingle Co. Kerry, I’m delighted to see the programme engage with its stakeholders at a local level, conveying its role in supporting the development of industry, research, heritage and tourism within coastal maritime communities”.

The INFOMAR Seminar will take place in the Dingle Skellig Hotel on Wednesday 16 and Thursday 17 October 2019. The event will include a special commemoration of the achievements of the Irish Baselines Project, and a live cast to MAREANO, the Norwegian marine mapping programme. Norway has just announced a new coastal mapping programme similar to INFOMAR which will complement the offshore activities of MAREANO. The event will conclude with a behind the scenes visit to Dingle OceanWorld Aquarium and to one of Ireland’s State research vessels, the RV Keary.

The event is open to all members of the public and interested people should register through the INFOMAR website www.infomar.com

#diving –In a landmark case today two divers from Kent have been made to pay a total of £63,500 in fines and costs for not declaring valuable items from shipwrecks off the UK coast.

David Knight and Edward Huzzey, both from Sandgate, had previously pleaded guilty to 19 offences between them, contrary to section 236 and section 237 of the Merchant Shipping Act 1995. Knight was fined £7,000 and Huzzey £6,500. They were each ordered to pay £25,000 in costs.

Items were taken from shipwrecks off the Kent coast, with the first known objects removed in 2001. The shipwrecks targeted included German submarines from World War I and an unknown 200 year old wreck carrying English East India Company cargo.

The items included eight bronze cannons, three propellers from German submarines, lead and tin ingots, along with various other artefacts. It's thought the combined value of the items is more than £250,000.

The MCA is aware from diary entries that Knight and Huzzey used explosives and sophisticated cutting equipment to free wreck material.

It's believed that six of the cannons had been sold on, but in the last fortnight they have been returned to the Maritime and Coastguard Agency (MCA).

Taking this into account in passing sentence at Southampton Magistrates' Court, District Judge Calloway, said: "The scale of the operation has to be considered to have been on an industrial scale: the resources employed were valuable and substantial, using good quality lifting equipment and explosives. Huzzey and Knight are friends and clearly operated in close co-operation to actively scavenge for material from the wrecks they explored."

Alison Kentuck, the MCA's Receiver of Wreck, said: "It is not a case of 'finders keepers'. Our message is clear: all wreck material found within or brought within UK territorial waters must be reported to the Receiver of Wreck.

"Finders of wreck have 28 days to declare their finds to the Receiver. This case demonstrates what could happen to you if you don't. By reporting wreck material you are giving the rightful owner the opportunity to have their property returned and you may be adding important information to the historic record.

"Legitimate finders are likely to be entitled to a salvage award, but those who don't declare items are breaking the law and could find themselves, just like with this case, facing hefty fines."

English Heritage has provided expert advice in relation to uncontrolled salvage on submerged archaeological remains and on the handling of the seized artefacts.

Mark Harrison, English Heritage's National Policing and Crime Adviser, said: "The sentence today sets an important precedent in the fight against uncontrolled salvage by a small criminal minority who have no appreciation for our national maritime heritage. Sophisticated techniques and equipment were used by these men to remove valuable artefacts from the seabed."

Mark Dunkley, English Heritage's Maritime Archaeologist said: "English Heritage takes very seriously all cases of heritage crime which robs us of our shared history. However, we recognise that the majority of divers do act responsibly and comply with the laws and regulations relating to historic wreck sites and salvage."

#Diving - With the Lusitania back in the news, Ireland's wealth of interesting diving sites are bound to draw attention this summer.

But it's worth remembering how dangerous an activity wreck diving can be - as Gizmodo reader Magicguppy relates in a special column for the tech news website.

He recalls his first ever shipwreck dive in September 2006, to the remains of the Rondo beneath the Sound of Mull in western Scotland.

"Used as a passage for shipping for centuries, it had a certain reputation for wrecking ships — even in 1935," writes Magicguppy, who goes on to depict in vivid detail how the ship went down, not to mention how the danger persists today for those who want to get close to the wreckage:

"The surface current swept my dive buddy and I towards the buoy. I turned and saw it gunning down on me. Grabbing the rope under the buoy, I signalled to my buddy.

"I knew that we had to get down below the current, and if we let go, even for a second, we wouldn’t be able to fight the current and get back onto the rope. My buddy agreed: Time to dive."

Gizmodo has much more HERE. But be warned - some of the gruesome descriptions in this story are not for the faint of heart!

#shipwreck – Silver recovered from the wreck of the SS Gairsoppa which was sunk by a German U-boat 300 miles southwest of Galway on February 17, 1941 is to be put on public display for the first time at an exhibition at Discovery Times Square in New York on May 24.

The SS Gairsoppa was a British steam merchant ship that saw service during the Second World War. The name Gairsoppa was given in honor of the stunning waterfalls in Karnataka, India. She sailed with several convoys, before joining Convoy SL 64. Running low on fuel, she left the convoy and headed for Galway, Ireland, until a German U-boat torpedoed and sank her.

The SHIPWRECK! exhibition features hundreds of authentic artifacts and historical treasures recovered from marine expedition firm Odyssey's deep-ocean projects from around the world.

Odyssey Marine Exploration recovered the silver from the 412 foot steel-hulled British cargo steamship at a depth of 4,700 metres below the surface. Recovery work began in 2012.

Odyssey recovered Silver from the wreck, which lies approximately three miles deep off the Galway coast will be going on display in the first public showing of some of the 1,218 silver bars of silver recovered the Gairsoppa, which is the heaviest and deepest recovery of precious metal from a shipwreck in history.

#Shipwreck - Two are reported dead after a shipwreck yesterday (Wednesday 10 April) on the Portuguese coast in what is a reminder to all cruisers of the dangers of strong winds in the region.

According to Portuguese language newspaper Publico, the deceased include one of the five crew of the German-flagged cruiser Meri Tuuli, and a member of the Portuguese maritime police attending to the incident who went into the water when his RIB overturned.

Eight people in total were admitted to hospital after the incident in which the Meri Tuuli - an X-442 yacht perated by a local sailing school - capsized on Cabedelo beach in Figueira da Foz, near Oporto.

Two are reported to be "wounded with traumatic injuries" while another two showed symptoms of hypothermia after exposure to the water.

Figueira da Foz is a popular cruising destination along the Iberian coast, but its port is vulnerable to the high swells that attract surfers to the area, sometimes closing altogether.

A source close to Afloat.ie described most harbour entrances along Portugal's west coast as "lethal during of after strong winter south or southwest winds" which are made stronger as air rushes into the valleys at river mouths as sea breezes.

Ireland's Offshore Renewable Energy

Because of Ireland's location at the Atlantic edge of the EU, it has more offshore energy potential than most other countries in Europe. The conditions are suitable for the development of the full range of current offshore renewable energy technologies.

Offshore Renewable Energy FAQs

Offshore renewable energy draws on the natural energy provided by wind, wave and tide to convert it into electricity for industry and domestic consumption.

Offshore wind is the most advanced technology, using fixed wind turbines in coastal areas, while floating wind is a developing technology more suited to deeper water. In 2018, offshore wind provided a tiny fraction of global electricity supply, but it is set to expand strongly in the coming decades into a USD 1 trillion business, according to the International Energy Agency (IEA). It says that turbines are growing in size and in power capacity, which in turn is "delivering major performance and cost improvements for offshore wind farms".

The global offshore wind market grew nearly 30% per year between 2010 and 2018, according to the IEA, due to rapid technology improvements, It calculated that about 150 new offshore wind projects are in active development around the world. Europe in particular has fostered the technology's development, led by Britain, Germany and Denmark, but China added more capacity than any other country in 2018.

A report for the Irish Wind Energy Assocation (IWEA) by the Carbon Trust – a British government-backed limited company established to accelerate Britain's move to a low carbon economy - says there are currently 14 fixed-bottom wind energy projects, four floating wind projects and one project that has yet to choose a technology at some stage of development in Irish waters. Some of these projects are aiming to build before 2030 to contribute to the 5GW target set by the Irish government, and others are expected to build after 2030. These projects have to secure planning permission, obtain a grid connection and also be successful in a competitive auction in the Renewable Electricity Support Scheme (RESS).

The electricity generated by each turbine is collected by an offshore electricity substation located within the wind farm. Seabed cables connect the offshore substation to an onshore substation on the coast. These cables transport the electricity to land from where it will be used to power homes, farms and businesses around Ireland. The offshore developer works with EirGrid, which operates the national grid, to identify how best to do this and where exactly on the grid the project should connect.

The new Marine Planning and Development Management Bill will create a new streamlined system for planning permission for activity or infrastructure in Irish waters or on the seabed, including offshore wind farms. It is due to be published before the end of 2020 and enacted in 2021.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE. Is there scope for community involvement in offshore wind? The IWEA says that from the early stages of a project, the wind farm developer "should be engaging with the local community to inform them about the project, answer their questions and listen to their concerns". It says this provides the community with "the opportunity to work with the developer to help shape the final layout and design of the project". Listening to fishing industry concerns, and how fishermen may be affected by survey works, construction and eventual operation of a project is "of particular concern to developers", the IWEA says. It says there will also be a community benefit fund put in place for each project. It says the final details of this will be addressed in the design of the RESS (see below) for offshore wind but it has the potential to be "tens of millions of euro over the 15 years of the RESS contract". The Government is also considering the possibility that communities will be enabled to invest in offshore wind farms though there is "no clarity yet on how this would work", the IWEA says.

Based on current plans, it would amount to around 12 GW of offshore wind energy. However, the IWEA points out that is unlikely that all of the projects planned will be completed. The industry says there is even more significant potential for floating offshore wind off Ireland's west coast and the Programme for Government contains a commitment to develop a long-term plan for at least 30 GW of floating offshore wind in our deeper waters.

There are many different models of turbines. The larger a turbine, the more efficient it is in producing electricity at a good price. In choosing a turbine model the developer will be conscious of this ,but also has to be aware the impact of the turbine on the environment, marine life, biodiversity and visual impact. As a broad rule an offshore wind turbine will have a tip-height of between 165m and 215m tall. However, turbine technology is evolving at a rapid rate with larger more efficient turbines anticipated on the market in the coming years.

 

The Renewable Electricity Support Scheme is designed to support the development of renewable energy projects in Ireland. Under the scheme wind farms and solar farms compete against each other in an auction with the projects which offer power at the lowest price awarded contracts. These contracts provide them with a guaranteed price for their power for 15 years. If they obtain a better price for their electricity on the wholesale market they must return the difference to the consumer.

Yes. The first auction for offshore renewable energy projects is expected to take place in late 2021.

Cost is one difference, and technology is another. Floating wind farm technology is relatively new, but allows use of deeper water. Ireland's 50-metre contour line is the limit for traditional bottom-fixed wind farms, and it is also very close to population centres, which makes visibility of large turbines an issue - hence the attraction of floating structures Do offshore wind farms pose a navigational hazard to shipping? Inshore fishermen do have valid concerns. One of the first steps in identifying a site as a potential location for an offshore wind farm is to identify and assess the level of existing marine activity in the area and this particularly includes shipping. The National Marine Planning Framework aims to create, for the first time, a plan to balance the various kinds of offshore activity with the protection of the Irish marine environment. This is expected to be published before the end of 2020, and will set out clearly where is suitable for offshore renewable energy development and where it is not - due, for example, to shipping movements and safe navigation.

YEnvironmental organisations are concerned about the impact of turbines on bird populations, particularly migrating birds. A Danish scientific study published in 2019 found evidence that larger birds were tending to avoid turbine blades, but said it didn't have sufficient evidence for smaller birds – and cautioned that the cumulative effect of farms could still have an impact on bird movements. A full environmental impact assessment has to be carried out before a developer can apply for planning permission to develop an offshore wind farm. This would include desk-based studies as well as extensive surveys of the population and movements of birds and marine mammals, as well as fish and seabed habitats. If a potential environmental impact is identified the developer must, as part of the planning application, show how the project will be designed in such a way as to avoid the impact or to mitigate against it.

A typical 500 MW offshore wind farm would require an operations and maintenance base which would be on the nearby coast. Such a project would generally create between 80-100 fulltime jobs, according to the IWEA. There would also be a substantial increase to in-direct employment and associated socio-economic benefit to the surrounding area where the operation and maintenance hub is located.

The recent Carbon Trust report for the IWEA, entitled Harnessing our potential, identified significant skills shortages for offshore wind in Ireland across the areas of engineering financial services and logistics. The IWEA says that as Ireland is a relatively new entrant to the offshore wind market, there are "opportunities to develop and implement strategies to address the skills shortages for delivering offshore wind and for Ireland to be a net exporter of human capital and skills to the highly competitive global offshore wind supply chain". Offshore wind requires a diverse workforce with jobs in both transferable (for example from the oil and gas sector) and specialist disciplines across apprenticeships and higher education. IWEA have a training network called the Green Tech Skillnet that facilitates training and networking opportunities in the renewable energy sector.

It is expected that developing the 3.5 GW of offshore wind energy identified in the Government's Climate Action Plan would create around 2,500 jobs in construction and development and around 700 permanent operations and maintenance jobs. The Programme for Government published in 2020 has an enhanced target of 5 GW of offshore wind which would create even more employment. The industry says that in the initial stages, the development of offshore wind energy would create employment in conducting environmental surveys, community engagement and development applications for planning. As a site moves to construction, people with backgrounds in various types of engineering, marine construction and marine transport would be recruited. Once the site is up and running , a project requires a team of turbine technicians, engineers and administrators to ensure the wind farm is fully and properly maintained, as well as crew for the crew transfer vessels transporting workers from shore to the turbines.

The IEA says that today's offshore wind market "doesn't even come close to tapping the full potential – with high-quality resources available in most major markets". It estimates that offshore wind has the potential to generate more than 420 000 Terawatt hours per year (TWh/yr) worldwide – as in more than 18 times the current global electricity demand. One Terawatt is 114 megawatts, and to put it in context, Scotland it has a population a little over 5 million and requires 25 TWh/yr of electrical energy.

Not as advanced as wind, with anchoring a big challenge – given that the most effective wave energy has to be in the most energetic locations, such as the Irish west coast. Britain, Ireland and Portugal are regarded as most advanced in developing wave energy technology. The prize is significant, the industry says, as there are forecasts that varying between 4000TWh/yr to 29500TWh/yr. Europe consumes around 3000TWh/year.

The industry has two main umbrella organisations – the Irish Wind Energy Association, which represents both onshore and offshore wind, and the Marine Renewables Industry Association, which focuses on all types of renewable in the marine environment.
