The last of Britains glaciers melted 10,000 years ago, but the way they shaped the landscape still affects our lives today. Locations of towns and cities have been determined by which direction those giant rivers of ice flowed; tourists flock to see the picturesque lakes and hills sculpted by their brute force, and gardeners curse soils with an overabundance of glacial clay.

Now those ancient ice sheets are reminding us of their existence out at sea too, influencing which locations are suitable for offshore windfarms. Gareth Carter, a marine geoscientist at the British Geological Survey, has been using subsurface imagery to map the land under the North Sea and advising engineers where to site their foundations for the huge Dogger Bank Wind Farm, 80 miles (130km) off the north-east coast of England.

Glacial sediments are highly variable, ranging from layered soft silts and clays, deposited in a lake formed by meltwater in front of the melting ice sheet, through to incredibly hard, chaotic and contorted deposits, dumped by a departing ice sheet, he says.

As windfarms move to ever deeper waters and rely on innovative anchor technologies to hold floating turbines in place, Carter and his colleagues are finding themselves in ever more demand, helping engineers to avoid troublesome boulders and identify suitable ground for foundations.

Shirley Robertson and Dee Caffari team up for a 2022 double-handed offshore campaign, building up to this years 1,800-mile Sevenstar Round Britain and Ireland Race.

Two of Britains most successful female sailors, Shirley Robertson and Dee Caffari, have teamed up for a 2022 double-handed offshore campaign, building up to this years 1,800-mile Sevenstar Round Britain and Ireland Race.

Dee Caffari and Shirley Robertson will be racing together on a new Jeanneau Sun Fast 3300, supplied by SeaVentures UK, having competed separately on boats of the same design last season.

The pair need little introduction. Caffari has achieved no fewer than six circumnavigations, three of them solo, two of them the wrong way around, eastabouts.

She skippered a Volvo Ocean Race team and a Global Challenge entry, completed a solo Vende Globe, and a double-handed Barcelona World Race. Last season she was racing with 22-year-old James Harayda, winning the RORC Double Handed National Championship.

Shirley Robertson is one of sailings most successful Olympic female athletes, having scored double Olympic Golds in Sydney and Athens. Shelater skippered an entry in the Extreme Sailing Series, and regularly competes on the superyacht circuit.

Robertson recently discovered a new love of offshore racing with the burgeoning double-handed offshore scene, which was bolstered by the hope that a new Mixed Two Person Keelboat Offshore event might be selected for the Paris 2024 Olympics. Last season she campaigned with Volvo Ocean Race and Figaro sailor Henry Bomby, the pair coming 2nd in the hugely competitive Rolex Fastnet Race double-handed division.

Robertson said: The double-handed offshore scene has grown hugely here in the UK, and although its relatively new to me, the last two seasons have been great racing. Im really looking forward to sailing with Dee for 2022, to be sailing with such an accomplished offshore athlete is very exciting.

Prior to teaming up for this campaign, Caffari and Robertson had not previously sailed together, although they regularly raced against each other last season. They will be entering seven offshore races on the new Jeanneau Sun Fast 3300, building up to the Sevenstar Round Britain and Ireland Race, which starts on 7 August, 2022.

The gruelling race will be, as Robertson notes, a big challenge in a 33-footer. The course is three times longer than the Rolex Fastnet Race,and sends competitors to the very northernmost tip of the British Isles, rounding Muckle Flugga.

Dee Caffari added: With our collective experience, we have a complimentary skill set so really hope to have an edge out on the water. I know, from competing against her last season, that Shirley knows how to sail a boat fast, so Im delighted that well be joining forces for the season ahead.

Shirley recently interviewed Dee in an excellent podcast, which is a fascinating discussion about life as a professional offshore sailor. We look forward to hearing more from the pair over the coming season.

Labor has committed to set pollution limits on the 215 largest polluting facilities and to tighten them over time.

What were seeing domestically is very high volumes of voluntary demand thats coming from large corporates and increasingly from investors and speculators like the big four banks, Mr Grossman said.

Deloitte Australia partner energy transition and decarbonisation John OBrien said Australian companies were buying certified carbon credits on the international market.

The Australian spot price for carbon credits is about $50 per tonne of carbon abatement but with cheaper labour costs overseas, credits can be bought for as low as $2 a tonne internationally.

Its a lot cheaper to buy good quality projects out of different parts of Asia than it is in the Australian market. Purely from an economic point of view, if a company is looking to offset, it saves money, Mr OBrien said.

Federal Energy and Emissions Reduction Minister Angus Taylor has established the Climate Active certification scheme, whereby companies can register their domestic and international credits and get certified if they achieve carbon neutrality.

Companies are required to use at least 20 per cent domestic carbon credits from land-based projects such as tree planting or agriculture.

Mr Grossman said companies were increasing their take-up of Australian carbon credits, which have risen in price from $15 a tonne to $50 over the past year. However, many investors arent surrendering their carbon credits to regulators to offset their emissions, opting to hold on to them in the hope of price spikes, or in case future government reform requires them to be used.

Many large corporates are stockpiling these Australian Carbon Credit Units (ACCU) in advance of future regulation to ensure that theyve got a pipeline of supply, if policy changes. Theyre also viewing ACCUs as a low carbon investment opportunity, Mr Grossman said.

Many climate campaigners are opposed to the use of carbon offsets, arguing they enable polluting industries to carry on with business as usual, without switching to more sustainable operations.

Australias big emitters look offshore to offset their carbon pollution - Sydney Morning Herald

Hitachi Energy has won an order from Samsung C&T Corporation, a large engineering and construction company, to connect ADNOCs offshore operations to the onshore power grid in the United Arab Emirates owned and operated by Abu Dhabi National Energy Company PJSC (TAQA).

Hitachi Energys HVDC Light technology and MACH digital control platformwill enable the transfer of cleaner and more efficient power from the mainland to power ADNOCs offshore production operations, enabling a carbon footprint reduction of ADNOCs offshore operations by more than 30%.

With a capacity of 3200 MW, the two HVDC links will be the most powerful power-from-shore solution in the Middle East and North Africa (MENA) region to date. It is also the first HVDC power-from-shore solution outside Norwegian waters.

The entire power-from-shore project will comprise two HVDC power links, which will connect two clusters of offshore oil and gas production facilities to the mainland power grid, a distance of up to 140 km for each cluster.

Hitachi Energy is supplying four converter stations, which convert AC power to DC for transmission in the subsea cables, then reconvert it to AC from DC for use in the offshore power systems. The HVDC technology will be supplied from Hitachi Energys global competence centers. Also included in the order are system studies, design and engineering, supply, installation supervision and commissioning. Hitachi Energy will support the customers with a long-term life-cycle service agreement leveraging digital technologies to ensure system availability and reliability over the HVDC links long operating life.

HVDC Light is a voltage source converter technology that was pioneered by Hitachi Energy. It is the preferred technology for many grid applications, including interconnecting national power grids, integrating offshore wind parks with mainland transmission systems, feeding more power into congested city centers, interconnecting asynchronous networks that operate at different frequencies, and power from shore.

HVDC Lights defining features include compact converter stations (which is extremely important in space-critical applications like offshore wind, offshore production facilities and city-center infeeds), low electrical losses, and black-start capability to restore power after a grid outage.

Representatives of Capital Energy held a meeting last November with Gran Canaria and Tenerife associated with the Maritime Cluster to present their offshore proposal and the implications that this proposal entails for the industrial fabric of the islands.The new agreement, which joins those signed during the last quarter of 2021 with the main Canary Islands shipyards, "responds to Capital Energy's commitment to the development of the territories in which it carries out its activity and confirms its commitment to this community, which it considers strategic for the development of offshore wind energy in Spain."

The memorandum of understanding with the CMC is the fourth strategic collaboration agreement signed by the company in the archipelago.The objective of this fourth agreement is to draw up a joint plan that identifies the services in the supply chain that are required to meet the needs arising from the future construction of offshore parks in the archipelago.This agreement will have five years of extendable duration.

The memorandum now signed succeeds those sealed by the renewable company with three Canary Islands shipyards during the last quarter of 2021: Zamakona Yards, Astican and Hidramar.Capital Energy considers the Canary Islands a "strategic region for the development of offshore wind energy".

In this sense, the company has also announced that it will continue to maintain contacts and promote the signing of agreements "with administrations, companies and local groups that can benefit from the driving effect that it plans to exercise with its activity in the Canary Islands."

Juan Jos Snchez, CEO of Capital Energy,said, We try to reconcile our contribution to the progressive decarbonization of the economy, through the implementation of renewable energies, with the promotion of economic and social development of all the territories in which we operate, as evidenced by the signing of this agreement with such a relevant Canarian entity that it will serve to promote our project in the offshore wind sector "

Antonio Vicente Marrero, president of the Canary Islands Maritime Cluster, added,This agreement with Capital Energy is an excellent example of the effort we are making from the Canary Islands Maritime Cluster to turn the archipelago into a territory that serves as an example of the sustainable development model in the that the economic policy is framed at the world level, with projects to create wealth and employment that respect the natural environment.Not in vain, the Canary Islands have been designated spearhead in the 'Road Map for Offshore Wind and Marine Energies' recently approved by the Government of Spain "

According to forecasts, Spain could have an offshore wind operating capacity of up to 3 gigawatts (GW) by 2030.In this context, Capital Energy aspires to start up a minimum of 750 MW of power, the development and construction of which would imply, at current prices, the investment of more than 3,500 million euros in the next decade.

About the Canary Islands Maritime Cluster

The Canary Islands Maritime Cluster is a regional non-profit association that declares as its primary objective "to promote the development and international competitiveness of the Canary Islands maritime marine sector, while raising the business, economic and social fabric of the Canary Islands through of the integration, creation, strengthening and sustainability of companies and institutions that are within the value chain of the maritime marine sector, promoting their international presence and increasing the technological and innovative level of all the agents involved, in line with the policies development and social demands ".The CMC's strategy to achieve this goal is based - they explain from the Cluster - on values such as cooperation, commitment, communication and competitiveness.

Offshore Wind Turbine Market to Witness Considerable Growth by 2028, With Key Players -ADWEN, Siemens(Gamesa), Siemens Wind Power, MHI Vestas Offshore...

Floating offshore wind startup Hexicon has started a joint venture with renewable power company Avapa Energy to bring Hexicon's twin-turbine floating foundations to Italian waters.

Italy stands to benefit from EU Green Deal project funding, Hexicon said, making it a natural market for offshore wind development. As Italy begins a program of regulatory change to enable offshore wind farm installation, Avapa and Hexicon will look for suitable sites and prepare for permitting opportunities.

"An important part of our business model is to enter new and promising markets as early as possible and to establish both our project development skills and technology together with local partners," said Marcus Thor, the CEO of Hexicon. "We have found a perfect partner in Avapa Energy, and with AvenHexicon we are looking forward to support Italy in its expansion of fossil-free electricity production."

Floating offshore wind will be an important component of a future zero-carbon energy mix, as the majority of the world's offshore wind resources are located in waters too deep for bottom-fixed foundations. Floating towers come with their own challenges, including periodic mooring maintenance, and their initial cost is higher than the expense for bottom-fixed projects.

Hexicon's approach to floating offshore wind is a bit different. The platform is centered on a single-point mooring, allowing the structure to rotate to face the wind. It has two outward-leaning towers, doubling the turbine count per mooring location. The company says that this helps save cost on installation by reducing the amount of steel per MW of capacity, reducing the number of inter-array cable lay runs, and reducing the number of platform tows and installations. The platforms and their canted towers are unique, but they use standard commercial turbines.

At present, Italy has no operational offshore wind farms; construction on its very first facility, the Taranto project, began in September. However, there is considerable market interest: In November, Italys Ministry of Ecological Transition said that it had received 64 expressions of interest in building floating offshore wind farms off the coast. The interested parties include big industry names, like Copenhagen Offshore Partners, Eni, Fincantieri, Fred. Olsen, RWE, Principle Power, Saipem, Falck Renewables and Vestas, among others.

Some of these expressions are already advancing. In December, Falck announced that it would partner with BlueFloat Energy on a proposal to install 90 floating turbines off the coast of Lecce, Italy. Compared to many floating proposals, he project would be relatively close in, with turbines located a minimum of seven nm offshore.

Wind farm in Quangdong is China's deepest offshore farm and includes turbines designed to withstand a typhoon (SASAC)

PublishedDec 31, 2021 6:33 PM by The Maritime Executive

China is moving quickly with its efforts to expand power generation from offshore wind farms. In the past week alone, the country reported the commissioning of three new projects, including Chinas largest offshore wind farm with the largest turbines, the first floating offshore wind farm that is typhoon-resistant, and expansion of projects in eastern China.

Chinas National Statics Administration recently announced that the country had reached 11.2 GW of installed offshore wind generation capacity. That would be up from 7.9 GW at the end of the first half of 2021 and would give China the largest operational base of offshore wind farms. The U.K. had been the global leader at the end of 2020 with 10.2 GW of generation capacity from offshore wind farms.

The new wind farms are helping China to overcome some of the challenges that have been seen to limit the development of offshore wind farms. The new farms include floating technology and turbines capable of withstanding the high winds and waves associated with a typhoon.

At present, wind farms are mainly located in the northwestern part of China, while eastern provinces have the largest electricity consumption, explained the China Institute for Studies in Energy Policy that is part of Xiamen University. The development of offshore wind farms is seen as a critical step for the eastern regions which have limited land resources to establish wind farms.

Construction was completed on a 300 MW offshore wind farm in the South China Sea. It is Chinas deepest offshore wind farm located in an area of challenging sea conditions with complex topography and geological conditions. The builders had to address typhoons, thunderstorms, and swells. The first of the turbines in the area was connected to the power grid in January and has generated 180 million kWh of electricity. Once fully in use, the project near Nanpeng Island in Guangdong province is expected to produce 800 million kilowatt-hours of electricity per year.

The floating offshore wind turbine installed at Guangdong and developed in China is designed to resist a Grade 17 typhoon, which would be a superstorm once every 50 years. The turbine has a capacity of 5.5 MW.

Chinas largest offshore wind farm in terms of single-unit capacity was also connected to the power grid on December 25. In Jiangsu province near the city of Qidong in eastern China, the farm has seven different models of wind turbines for a total of 134 installed. The first turbine was erected in February with the last completed in early December. It is part of an overall project located about 18 to 25 miles offshore in the Yellow Sea which will have a total capacity of 802 MW.

The first phase of the Guodian Xiangshan 1 Offshore Wind Farm project in East China's Zhejiang Province became fully operational on December 23. It has 41 6.2-megawatt wind turbines connected to a 220-kilovolt offshore booster station. It is the second offshore wind power project developed by GD Power Development Co. giving the company a total of 506,200 kilowatts of installed offshore wind power capacity put into operation in the province. The Xiangshan 1 wind power project, the first offshore wind power project in Ningbo, started on December 25, 2020.

The wind power projects are part of the countrys effort to reduce its dependence on coal-fired power plants. Chinas goal is for carbon dioxide emissions to peak by 2030. The country declared it will be carbon neutral by 2060.

China Commissions Offshore Wind Power Giving It Largest Installed Base - The Maritime Executive

DEME Offshores jack-up Sea Installer has left the Port of Hull loaded with the last batch of turbine components to be installed at the 1.32 GW Hornsea Two soon to be the worlds largest offshore wind farm in operation.

Sea Installer and Sea Challenger have been transporting the wind farms 165 Siemens Gamesa 8.4 MW turbines from Siemens Gamesas facilities in Hull and installing them at the site some 89 kilometres north-east of Grimsby, the UK, since May.

Sea Installer is expected to reach the installation site at around 3 pm UTC, Friday, 31 December. Sea Challenger is currently at the installation site.

Seeing that these will be the final runs for both vessels on the project, it is safe to assume that Hornsea Two has already claimed the top spot in terms of the installed capacity from its sister project the 1.2 GW Hornsea One.

Hornsea Two is being developed by rsted and is scheduled to be fully commissioned in the first half of 2022.

The wind farm delivered first power to the UK grid earlier this month.

First power was achieved after the wind farms offshore substation, the worlds largest offshore AC substation, and reactive compensation station (RCS), were installed in late October 2021.

Once fully completed, power will be transferred from the 165 wind turbines via 373 kilometres of array cables to the OSS and RCS, reaching the national grid via 390 kilometres of offshore and 40 kilometres of onshore export cables which terminate at the onshore substation in Killingholme.

A further two projects in the Hornsea Zone are also underway with Hornsea 3 receiving a Development Consent Order in December 2020 and Hornsea 4 currently going through the planning process.

Final Turbines Head to World's Largest Offshore Wind Farm - Offshore WIND

rsteds Skne Havsvindpark (Skne Offshore Wind Farm) project offshore Sweden is planned to enter construction in 2026, subject to permitting process and final investment decision, and it looks like the developer expects to see wind turbines of more than 20 MW on the market by that time.

Namely, a consultation document rsted issued before submitting an environmental impact assessment (EIA) for the Skne offshore wind farm this September shows that the 1,500 MW project could comprise as few as 55 wind turbines, depending on the nominal capacity of units to be used, which in this case would be 27 MW.

The company is looking at installing a maximum of 125 turbines at the project site in the Baltic Sea, approximately 22 kilometres south of Skne,if a 12 MW model is used. With 20 MW turbines, the number would drop to 75 units and further to 55 if each of the wind turbines has a 27 MW capacity.

A 27 MW unit would have a rotor blade diameter of 320 metres and a maximum blade tip height of 385 metres.

At the 451-square-kilometre site, the turbines would be placed four to five times their rotor diameter from each other, according to the developer, with their exact locations within the site also depending on seabed and other conditions.

The project could comprise up to four offshore substations and the foundations planned to be used for the wind turbines and platforms could be monopile, jacket, suction bucket, or gravity-based foundations.

The construction of the wind farm is planned to start in 2026 and the 1.5 GW Skne project would be fully built in 2029, subject to weather conditions.

In 2026, works on the electrical system onshore would start, including the substation and the onshore part of the export cable, followed by offshore cabling along the export cable route in 2027. The following year, offshore substations would be installed and the installation work on foundations and inter-array cables would begin, with wind turbines planned for installation in 2029.
