Vision for Offshore Wind Energy Market

Offshore WindThe offshore wind industry made significant strides in Europe last year, according to the European Wind Energy Association (EWEA). This growth has broad implications both for the renewables industry and the subsea cable market.

EWEA’s “Wind in Power: 2015 European Statistics” report published in February 2016 said European offshore wind installations more than doubled in 2015 from the year before. Germany had by far the most wind-power activity in 2015, adding 6,013 megawatts of generating capacity — and 38.4% of that was offshore.

Offshore wind installations accounted for 33.4 percent of all installations in 2015, according to EWEA’s data, up from 13.7% year before. Furthermore, investments in wind power hit an all-time high in 2015, EWEA said, with offshore wind leading the charge.

“Financial commitments in new assets reached a total of €26.4 billion, a 40 percent increase from 2014,” the report said. “While investments in new onshore wind generating assets increased by 6.3% in 2015, those in the offshore wind sector doubled compared to the previous year.”

A summary of the report in the website OffshoreWIND.biz notes where most of the capacity was added in 2015:

  • Germany: 2,282 megawatts (75.4%), a four-old jump from the year before
  • UK: 566 MW (18.7%)
  • Netherlands: 180 MW (5.9%)

Another EWEA report, “The European Offshore Wind Industry — Key Trends and Statistics 2015,” drills deep into the details of the continent’s offshore power industry. It notes that “total investments for the construction and refinancing of offshore wind farms and transmission assets hit a record level of €18 billion.”

At PMI, we’re watching the growth of offshore wind closely because it has the potential to affect all the players in the subsea cable market. After all, those wind turbines depend on offshore cables to transmit power back to the mainland (the average turbine site was 43.3 kilometers from shore in 2015, in 27.1 meters of water). As sites near shore become more fully developed, offshore sites will inevitably move farther away and into much deeper water.

Those developments mean offshore cables and equipment like subsea cable terminations will need to be extremely tough and reliable — the two signature qualities of PMI cable equipment.

Damage to Subsea Cables a Huge Risk to Offshore Wind Farms

Underwater CablesAny young, new industry will have growing pains, and the offshore wind farm industry is no different. Among other issues with offshore wind farms, one of the biggest problems to affect the industry are issues with subsea cables. Failures and issues during installation and maintenance of subsea cables have cost companies millions of dollars and have caused many delays in this new and quickly rising industry.

While much information on cable issues is closely guarded, there have been some high profile cases as well as some studies done regarding damage to offshore wind farms. One of these studies, conducted by the Bureau of Safety and Environmental Enforcement (BSEE), partially delves into issues specific to subsea cables. Failure statistics have shown that third party mechanical damage to cables is three to five times more likely that the risk of internal cable failures. A few examples of third-party subsea cable damage include:

  • Jackup “Jacked Up” On a Cable:

One issue is the risk of Jackups “Jacking Up” on a cable. A Jackup is a floating barge fitted with long support legs that can be raised or lowered to service oil and gas platforms or wind turbines. According to the study by the BSEE, there have been issues with cables getting caught in the jackup and being damaged in the equipment.

  • Anchors Damage To Cable:

Another common issue is damage from third party anchors. Often times, anchors of laying vessels will tangle with the cable being laid and cause damage to the cable.

  • Cable Kinked

Perhaps one of the most common issues with subsea cables is their tendency to kink or bend. It is very easy to get a kink into the line when preparing to install cables and unkinking is a major exercise requiring special skills.

In addition to these issues, other common problems to cable installation can include: damage to cable during installation, weather or soil-related damage, cable or joint failure, or sediment movement that can lead to cable exposure.

Subsea cables are complicated pieces of equipment and need to be handled with care and should only be used with only the best cable hardware to promote longevity and fortification. PMI is ready to equip your cables with the highest quality cable hardware.

How geography is shaping the offshore wind industry

Offshore Wind Industry

While it appears as thought the U.S. is falling far behind Europe in the Offshore Wind and Wave Energy department, you really need to understand the lay of the land – literally.

 The U.S. coastline, with a relatively small continental shelf, is not quite as amenable as Europe’s North Sea for offshore wave and wind. Conventional offshore wind turbines are limited to a depth of around 50 meters. In these depths, foundations are typically open truss frame structures that are anchored to the seabed. They are expensive to build and aimed at supporting extremely large turbines. The larger the turbine, the more energy it produces, keeping the overall cost per kilowatt-hour down.

But as the water depth increases, foundation costs increases. So along the U.S. coast, floating structures similar to the ones deep-water oil and gas industry use are nearly the only option.

The U.S. would benefit from not only looking at floating offshore wind but also wave energy, both of which are economically equal in extracting energy from the marine environment.

But what is most important is that these types of projects get in the water soon, generate interest and start working towards lowering costs. We need to work to achieve lower costs through simplicity, reliability and economies of scale.

Today it appears that we are likely only to employ only a tiny fraction of this available resource and offset the needs within the U.S. The problem we truly face is not obtaining the resource; it is the practical deployment and the economical conversion of it into electricity.

We need to look at the most viable methods of capture it at the lowest cost.

Our years of experience in the offshore oil and gas industry will benefit offshore renewable energy companies that are navigating along the U.S. shoreline.

Meet with a PMI Engineering Expert who will help you tackle your offshore project needs.

Rivers in rural areas are a huge focus for the renewable energy field today


For decades, PMI has been extremely focused on building the best products that withstand the extreme environments of the deep ocean. But as we’ve come to work with Offshore Wind and Renewable Energy companies, we understand our product doesn’t have to be used in the deepest and harshest place on our planet, the sea. Instead, rivers in rural areas are a huge focus of the renewable energy field today. And these companies are offering solutions that serve a large portion of the population, who still have no access to electricity.

……………………………………………………………………………………………………………………

We see a great future in the power coursing through our rivers. And, of course, we will be providing cable equipment for these projects as they evolve. If you want to know more about our custom engineered cable hardware equipment, schedule to talk to our experts today.

……………………………………………………………………………………………………………………

India is facing an energy revolution. Despite broad grid coverage, electricity supply in remote areas remains unreliable. For the future, the government is setting a favorable political scenario by introducing solutions for decentralized electrification based on renewable energies, such as photovoltaic (PV), small wind, and explicitly kinetic hydropower.

Companies such as Smart Hydro Power have the advantage of realizing its systems in rural areas, without the requirement for any kind of infrastructure, suitable for running canals, rivers and streams, which inhabit a large portion of India’s typography. At the distribution part of this system, integrated load management introduces an auxiliary productive load – a water purification plant – that utilizes all excess energy and stabilizes the micro grid with variable operation. Through this feature, additional value is brought to the lifestyle of people residing in these communities. Read more…

The main ambition behind the development of the Smart Hydro Power turbine was cost efficiency. Selected materials had to be robust and yet affordable which resulted in a majority of HDPE, aluminum and stainless steel components. The turbine consists of a three bladed rotor, a 5 kW generator, the floating body consisting of a three piece diffusor and two floats.

Subsea hardware is a natural fit for river energy exploration

Drawing energy from river currents represents a massive untapped source of electricity development. This is especially true in countries like Canada, where rivers and coastal waters provide an enormous range of development options that can provide growth and economic benefits.

Indeed, Canada is emerging as a leader in the global marine renewable energy industry, thanks to supportive government policies, shared infrastructure and strategic research initiatives. These facts provided the backdrop for last week’s Marine Renewables Canada 2015 Annual Conference, where PMI was among the vendors showcasing products and services in the fast-growing renewables market.

At PMI, we’re already reaching out to companies in the offshore-wind sector, and we’re seeing the potential of freshwater rivers to provide clean, renewable energy.

River energy initiatives provide a new twist on age-old technology: the water wheel. New ventures in this sector are exploring placing turbines — much like you’d see on a jet aircraft — deep in the waters of a river. Water turns the blades, generating kinetic energy that can be converted into electricity.

This creates the potential to fix the one major drawback of hydroelectric projects: massive dams that devastate the local environment. Rivers also can provide power around the clock, unlike solar panels.

Canadian businesses and researchers are unlocking the potential of marine renewable energy through innovations and new approaches to key challenges in the lifecycle of wave, tidal and river projects. Solving problems here definitely opens opportunities in the global market.

PMI is proud to be on the cutting edge of this opportunity, supplying contractors with our proven subsea hardware equipment for river energy exploration. At Marine Renewables Canada 2015, we gobbled up knowledge on topics including:

  • Technical acceptability — an international effort to reduce technical risk
  • Building scale — an international project pipeline
  • Supplying the industry — device development

 

We see a great future in the power coursing through our rivers. And, of course, we will be providing cable equipment for these projects as they evolve. If you want to know more about our custom engineered cable hardware equipment, schedule to talk to our experts today.

Cost efficiency and simplified solutions are top-of-mind for those in offshore wind

Offshore wind might be a new industry, but they are as just as focused on cost efficiencies and simplified solutions as our clients in oil and gas. Those who support them need to supply and produce reliable products that increase performance and lower costs.

Our past customers pushed us to innovate and develop “No Tools Required” custom cable systems, and our in-depth hydrodynamic efficiency studies are helping other companies innovate new systems on existing subsea cable devices and analyze cost saving opportunities.

And we are not alone in our efforts. German industrial group Siemens unveiled a new direct-current solution for connecting offshore wind turbines to the grid which can lower costs by as much as 30%. Read more.

Offshore wind is taking our world by storm

You may not have noticed, but offshore wind is taking our world by storm.

Since offshore wind turbines are transported by ships and barges, they easily reduce logistical challenges that land-based turbines encounter, such as narrow roadways or tunnels. This allows offshore wind developers to build larger turbines capable of producing more electricity.

But what’s really exciting is that offshore wind turbines can float. Several U.S. companies are developing innovative floating offshore wind platforms for use in deep waters. These floating platforms are placed in water depths where bottom-mounted towers are not feasible. Their structures are tethered to the seabed with cables.

And where there are cables, there is cable hardware.

We’ve been creating subsea cable hardware for years. Today our products, which offer protection against cable bending and abrasion, are being adapted for the renewable energy field.

This need for subsea cable hardware will be on the rise right along with the demand of
clean, renewable energy to fulfill the electrical needs of cities along U.S. coastlines. And being located near the east coast, where many of the first offshore wind farms will be developed, means we are a close resource for the industry.

Offshore wind’s growth rate needs to be matched by an equal pace in reducing costs


Although we are located in the States, we assist companies world-wide with marine cable hardware, deployment, and management. Therefore, we’ve had a front row seat watching Europe position itself as a leader and pioneer in addressing climate change, creating jobs in the offshore wind sector, and reducing fossil fuel imports.

And while offshore wind is years behind onshore wind, the industry is displaying one of the fastest growth rates in the industry. The pace of growth, however, needs to be matched by an equal pace in reducing costs. Success will depend not only on how much it can reduce costs, but also how fast it can reduce costs.

As the U.S. starts installing the foundations for their first offshore wind farm, they will have these same issues to contend with as well as the struggling opposition found along our coast.

Read more about offshore wind here.

Read more about North America’s first offshore wind farm:
Rhode Island’s Deepwater Wind will start installing the foundations for North America’s first offshore wind farm on Monday, a milestone the company says could pave the way for an industry long established in Europe but that is still struggling with opposition in the United States.
