Who knew high voltage cables running for kilometers in a deep electrolytic moving body of water would be expensive?

Despite offshore windfarms dealing in a kind of mechanical hell of high speed salt water spray, big waves and volatile wind conditions, surprisingly 85% of the insurance claims are because the underwater cables are failing.* If the subsea cables can’t be insured, it’s another unexpected cost threatening the economics of offshore wind.

The underwater cables needed for offshore wind are apparently so costly to repair, and the losses from lack of generation so steep, they are in danger of becoming uninsurable.

Subsea cable failures pose global threat to offshore wind

Energy News Live

The race to harness offshore wind energy has hit a significant roadblock, with the reliability of subsea cables emerging as a critical concern.

Global Underwater Hub (GUH) has raised alarm bells about the escalating issue of subsea cable failures.

These setbacks not only disrupt power transmission but also incur hefty costs.

Imagine if an entire coal plant was connected to the grid through one long cable buried under the ocean and when the cable failed it took months to find and repair — during which time the plant could not earn a cent…

Subsea cable failure could derail global offshore wind projects

World Oil

GUH chief executive, Neil Gordon, said, “It’s estimated that around 85% of the total value of offshore wind insurance claims relate to subsea cables. Insurers are losing money underwriting cables with the average settlement claim in the region of £9 million. Brokers have warned that the high number of cable claims is affecting capacity and coverage and the cost of repairs typically runs into millions, with warranties rarely covering the high cost of business interruption.

“If these critical components become uninsurable, offshore wind projects around the world will be derailed, making global 2050 net zero targets completely unachievable.”

According to one developer, the cost of insuring a 1.2GW offshore wind farm over its lifetime is in the region of £350 million and insurance brokers estimate that the costs of floating offshore wind will be 30% higher than fixed bottom ones.

Global Power Marine fixes export cables and quotes one happy customer talking about needing “only” 32 days instead of 67 days to repair the cable.  But all the while, part or all of the wind plant isn’t earning any income, and so much of any repair depends on getting good weather so a ship can hover and work uninterrupted while the cable is “dangling” and exposed.

Gulski et al estimate the duration of failure can be 1 to 3 or even up to 9 months:

“Last 20 years of experience shows that the power cables are the largest contributor to the failures of power supply from the offshore plants. “

For those who want the details on the challenges of engineering  Gulski et al detail some of the problems with subsea cables like the need for armour that isn’t magnetic, sections that are 30-50 kilometers long to avoid “joints” underwater, and why most cables on the sea floor are called “wet structures” which allow water in (at least to the outer layers).

Wind energy might be free, but collecting it costs the Earth.

Late Update — Australia desperately needs to learn these lessons

Prompted by comments from David Maddison and Ross below:

There are no offshore wind plants in Australia but we are rushing to build them, so the tales of woe from the UK and US are especially relevant here now.

The Basslink Cable from Tasmania to mainland Australian has broken not once, but three times here in the last seven years. First in 2016 for 5 or 6 months (I believe Australia didn’t even have the right repair ship, we used the Ile De Re which was based in Jakarta). Then the cable was out again in 2018 for two months. And in 2019 for another month due to a problem on land at the Victorian end.

The Basslink repair in 2016 were delayed for weeks because of bad weather.

After three weeks of delay, the ship was finally able to leave Geelong last night and the repair team hopes calm conditions will last long enough to connect a new section of cable to the existing one. The repair team needs 16 calm days to work on the cable before it can be up and running again.

How could our BOM even predict 16 calm days on the Bass Strait…?

_______________

*Admittedly, this percentage may be high because insurance companies don’t cover most of the other kinds of failures on wind “farms”, as we see with Siemens massive stock loss as they realized the true cost of maintenance.

    fascinating. Pollies just keep throwing money at this, like the recently departed Dan of Le Mancha. We are burning through our amazing civilisation grinding gears on the basis of communist subversion. I notice the entire electrical infrastructure is vulnerable. If there were real wars, electricity would be easy to knock out. Similar to fibre optic communications. Instead we have “1984” wars to make our leaders safe in incumbency.

      The generators are not the weak link as we have been finding; the connectors are. So easy to destroy a transmission tower or underwater cable and so difficult to protect them. Imagine patrolling thousands of kilometers of transmission through forrest areas or open spaces especially now with drones that can be programmed to attack small targets. Worse of course is the fact that much infrastructure only functions for 30% of the time and our capacity to defend ourselves is in jeopardy. Our potential adversaries must rub their eyes in wonder at our stupidity.

          It used to be that all communications cables were Copper, but that’s no longer used although there’s still a lot of those old analog phone lines under city streets.

          Water pipe used to be mostly steel, but then moved over to Copper which lasts longer. Now at least the cold water is moving to plastic, resulting in a major reduction in Copper demand and also opportunity for recycling.

          Taps and various other fittings used to be 100% brass but that’s changed and they are still partly brass but often involve some plastic, Aluminium and other stuff.

          At some stage I would guess hot water pipes might also go iver to plastic, and perhaps same thing will happen for gas pipes as well. Many people have named some resource or other and said, “Golly it’s gonna run out” but those people are typically wrong.

    Tonight we are told that Scottish Power ( based in Perth) has had a lower than expected output from their Wind ( due to extreme weather events, they say), and / but – Yes, and/but, there are MORE Companies waiting to get permission or start( having got permission) to build more windmills in the Sea, and West of Orkney, too. Maybe they don’t read the trade magazines, or?
    And then in the next Breath NW Sutherland’s Space port site is expecting to send up 12 rockets next year, or so. Hope nothing goes wrong there, either, or they may end up crashing into and burning al l that PEAT which they’re trying to “save”.

    Remember when the Basslink subsidy-harvesting cable between Van Diemen’s Land and the Mainland failed? It took at least six months to repair. (The cable would have been unnecessary had we continued to use inexpensive, reliable coal power.)

    Also, all these underwater cables will be highly susceptible to sabotage by hostile foreign powers, although forcing us to use expensive and unreliable wind power is a form of sabotage in itself. (A vast majority of our politicians are loyal to the UN, Herr Kommandant Schwab and the Chicomms.)

And in 2019 for another month due to a problem on land at the Victorian end.

          In my speeches about How to Destroy an Electricity Grid I made hay with the Basslink debacle for years afterwards at every speech, lining up the slides of the dam levels, the half billion dollar cost of the outage, and how they could have bought two gas plants nearly for that instead, and the fact that they cloud seeded in the face of a historic flooding rain in their greed to refill the empty dams.

          I feel (perhaps wrongly) that everyone knows that story…

        I thought that they fried the cable, trying to push too much power through it. I remember the discussions at the time, and nobody was prepared to say whether the cable had been pushed beyond its specified limits or not.

        • #

          Indeed Graeme#4, you are right:

          The report on the Basslink 2016 breakage

          The Basslink Cable was supposed to allow 630MW of energy to go back and forth, but according to Tas Hydro can only deal with 500MW.

          “BPL believed its cable could safely and reliably operate at 630MW for extended periods without overheating the copper and insulation and causing an unreasonable likelihood of failure,” Mr Davy said.

          “Unfortunately, they were wrong. The expert reports note that the cable, as designed and constructed, cannot meet the minimum operating requirements.”

          There goes another 130MW Victoria was hoping to use in peak hours over summer:

          “Victorians have been expecting to rely on 630MW of peak power over summer, and if that’s reduced to 500MW that will have significant impacts on how Victoria sources that power on the hot days of summer,” he said.

      Turbine not spinning while cable fault is repaired + undersized shafts and bearings on turbines = what could go wrong?

      I am curious ?…..
      Why do you assume the turbines blades have to stop spinning whilst the cable is repaired ?
      And how is using a generator to power the turbine blades any different to letting the wind do it ?
      Undersized shafts and bearings .??
      A generator may well be needed if there is no wind, but if the wind is available ..??

      • #
        Broadie

        Good question Chad?

        The problem is the wind is fickle and you are not powering a generator with consistent force allowing the parts to arrive at some steady state equilibrium.

        Extremely unsteady operating conditions are characteristic for wind turbines and it is considered to be
        one of the reasons of frequent failures [8] – Figure 6 shows an example of changes of power generated
        by a wind turbine with four peaks of over 1000 kW and one drop to 400 kW in just 120 seconds.

        Engineers are working on the problem of the continually changing loads.

        Roller element bearings are vulnerable to the conditions of loading and unloading, which causes
        sliding of the rolling elements [9]. As explained in Figure 7 [9] the rolling elements leaving the loaded
        zone are disengaged from the inner raceway due to centrifugal forces and their rotational speed is
        lowered considerably. Then entering the loaded zone again the elements become accelerated, but their
        inertia opposes such acceleration, so the elements slide with respect to the raceways and excessive
        heat is generated causing overheating, structural changes and even adhesion in metallic contact areas.
        This failure mechanism is often referred to as smearing or adhesive wear.

        So in answering your query. When the cable is disconnected the rotation of the blades would have to either be stopped or regulated. I do not know how this is controlled, though I remember previous posts where the turbine was kept rotating by diesel standby or access to the power grid to avoid uneven loading on bearings

        Most of the turbine gearbox issues are generic in nature, and are not related to any specific
        wind turbine or gearbox manufacturer. Failures can be connected with converged construction
        solutions. Therefore, failures may be associated with design assumptions rather than with
        calculation methods used for evaluation of the durability of individual components

        The problem appears generic and worldwide and I doubt salt water will be good environment to search for a solution.

          I dont think it is easy to mechanically decouple the blade shaft from the generator .?
          To regulate blade speed, I assume they would ectrically decouple the generator from the system and link it to a dump resistor pack, then use the mechanical brake and vane feathering controls to maintain a minimum rotation speed …whilst the wind is blowing.
          And with respect to that bearing comment, my understanding of large roller bearing applications is that they should always be designed into an assembly that ensures thay always have a set preload to prevent those exact problems.
          And Brinnelling is a different problem altogether.
          But what was that comment about undersized shafts and bearings ?…it sounds like a very fundamental design mistake.

    When I worked on superconducting generator design and development for ratings up to 1300MW I learnt that reliability/availability/maintainabilty were key to the economics. This was in the 1970s-80s for the UK’s CEGB.

    The rule-of-thumb was that 4 days outage would result in excess costs (e.g. due to running plant from lower in the merit order) equal to the capital cost of the superconducting generator. In what way have matters changed?

    John.

      I note that the company that has taken over the Sun cable project is now saying that they will subcontract the cable out to somebody else, and meanwhile only supply power to Darwin. This is stupid. Darwin doesn’t need that amount of extra unreliable power, and I believe that already there are two solar projects waiting to gain approval to connect to the NT grid.

I understand one large solar farm is waiting for a neighbouring pumped hydro to be built while others are exploring hydrogen storage to make their project viable.

        not planning to pay for the cable

        Graeme, I saw that article as well.

        I had a look at why that may be.
        OK, it is quite hilly up and down on the seabed for approx 1200 km of the link.

        This is the crossection of the proposed Sun Cable link. Sea floor levels with surface plan.

        https://link.springer.com/article/10.1007/s41825-020-00032-z/figures/4

        The proposed cable is 4200 km long, yet the plan length is 3200 km…. So 1000 km extra is needed to go up and down the steep sub sea hills, with the associated engineering problems.

        So Mike C-B is now going to let a contractor deal with that problem… I understand why.. It is an major engineering risk/challenge.. so if it fails, someone else can be the patsy.
        It seems that if your qualification is a tech/software engineer…. that’s what you do.

        One thing that I have always pondered… Do these companies ever pay back (or are liable) for their gov taxpayer funded subsidies?

        They are not only paying for the cable they are paying for the sub contractors profit. They have (if they ever find a contractor) transferred the risk, reduced the noise and stopped people talking so much about the elephant in the room.

    Offshore wind generators are simply the worst solution to the non problem these leftist idiots have created by demonising CO2. It beggars belief that anyone would think placing electrical generators in sea water is a good idea….just from a maintenance point of view, let alone the fragility of cabling back to the shore. It’s simply nuts. Build a new coal fired power generator next to the recently shutdown Liddell…or place wind turbines in the sea ? Ask any real engineer what the best choice is.

        Minyang [Chinese] MySE 18.X-28X is reportedly 280 metre rotor diameter.
        Likely to be (well?) over 350 metres to top of the blade arc.

    Most younger engineers, as with most “professionals” these days will be fully dumbed-down and fully woke and thus have no clue.

    But there will be a small minority of engineers that were properly educated before the current madness.

    Such engineers are being unethical and unprofessional if they don’t speak out against the insanity of wind and solar, even if it means losing their jobs although hopefully they wouldn’t lose jobs.

      I have a recent experience with an older engineer. I am thinking of sending him a seeing-eye dog as he reported to a Court that not one but two drains did not exist, both historically or as built.

      I am tossing up reporting him to his peers as he was actually discrediting the work of his fellow engineers. I call his Court performances ‘Engismearing’. He relies on the fact that a contesting Engineer will not give a 100% certainty to any contrary argument. There is always a possibility after all.

    Woodside’s gas hub has been halted by an activist judge gulled into listening to an aboriginal woman who says she knows what whales are singing about 100 kms out to sea. Bowens off-shore wind sites in NSW sit astride the migration route of 25000 whales that each year go North to calve and South to mate and feed. There must be many aborigints who can hear their distress calls a mere 20 kms away.

      I doubt whether any traditional Aborigines were even aware of whale song or if they happened to have their heads underwater at the time, whether they were aware what made the sounds or their meaning, if they could hear them at all. (Those portions of song that were in the audible spectrum.)

      As per my Sky News post the other day, you can forget about offshore development if the Yes vote wins.
      The indigenous (at least the non-white indigenous) will ban such things as they will impact turtles swimming 200km offshore or similar nonsense.
      YES – Proudly sponsored by das gubermint, the AEC and Pfizer.
      That alone should rule them out.

      Earthquakes, volcanoes, sharks, extreme pressures, hostile environments, naughty non-government people with explosives – the oceans are dangerous places for innocent cables.

          “We all have a voice, what we don’t have is listeners.”

          Yes – feels like that here in the UK, too.
          But – the Uxbridge and South Ruislip election gave a little hope.
          Rishi saying that the Internal Combustion Engine [ICE] for car ban will be postponed until 2035 [like the EU’s own ban, oddly!] gave a little more hope.
          But it’s all just Pollies’ wind.
          The requirement for manufacturers to sell [not make, actually sell] 22% of their output as Electric Vehicles [EVs] from 2024 [i.e. in about three months time] is still in force, and it’ll rise [in the UK] to a quota of 80% by 2030 [no, not 2035!].
          I haven’t checked the actual legal requirement [failure to meet that quota will be punished by a £15,000 fine for EVERY car over the ICE quota!]. But I think it’ll look something like this:
          2024 22%
          2025 32%
          2026 41%
          2027 51%
          2028 61%
          2029 70%
          2030 80%
          [I repeat – my guesses only, but they’ll likely be modestly close].

          So – in fifteen months, a third of cars sold are to be EVs?
          Given the well known problems of EVs – Price; Range; Charging; Software issues; and general flammability with little or no solution – and given the increasing prevalence of fires from lithium batteries – here’s one more today [a phone!] https://www.bbc.com/news/articles/cqq76vv4dzno – and their increasing prominence in the news, I suspect things will not get better for the EV makers.

    Here’s another problem with wind turbines.

    At night they need flashing red lights to warn aircraft.

    Well, the flashing lights are annoying people so the answer is to turn them off.

    What could possibly go wrong?

    https://www.kuow.org/stories/washington-pushes-back-on-light-pollution-from-wind-farms

    Those blinking red lights seen on wind turbines will have to go dark in Washington, unless there’s an airplane flying nearby.

    That’s because Gov. Jay Inslee just signed a bill that restricts the nighttime use of the lights for both new and old wind farms.

    The flashing lights on wind turbines are supposed to keep aircraft safe and help to avoid collisions, but state Rep. April Connors (R-Kennewick) said they’re distracting for drivers on the ground.

    “Over 100,000 people live within six miles of the turbines in numerous fast-growing residential communities, mostly inside city limits,” Kennewick resident Paul Krupin said at a public hearing earlier this year, in reference to a proposed Horse Heaven Hills renewable energy project.

    As more wind farms are built, Rep. Connors said she worries about light pollution. She’s been pushing for wind farms to add detection radars, so the lights come on only when necessary. A bill was passed last session that does just that.

      Agree but they use the weasel excuse is that they were advised by their “experts” on the best available science! We all know that these ‘experts’ are the ones that will give them the answer they want. Plausible deniability. But how to combat this is the problem. They will not listen to any advice/fact that contradicts their plans, until, of course, the public eventually catch on, by then the damage is done and they are safe because the “experts” advised them.

    This section was particularly interesting:

    References [6,10] have identified the following major problems often resulting in cable failures:
    • The most common root causes of failure claims range from contractor error to design defects, mechanical failures and weather influences;
    • Technical solutions are constantly under development to target specific problems that occur during installation and operation;
    • The managing of human errors is still arguably the greatest challenge;
    • The cost and time pressures are the root cause of human errors, resulting in failures occurring during operation;
    • The pressure to reduce levelized cost of electricity triggers questionable decisions on both the developers’ and contractors’ sides;
    • The offshore industry is focused on strongly driving down the costs with less room for motivating development and innovations;
    • There is no transparency and consistent dialogue between different project teams and suppliers.

    Not only that profit was the driving force of most of the problems, but that “Technical solutions are constantly under development to target specific problems that occur during installation and operation” is listed as a problem, which hints at even more profit-driven milking of the government teat. What this really reveals is that they are a bunch of amateurs milking the government, not a bunch of professionals working to establish a long-term industry on which we will all depend.

    You have to laugh at the first entry “The most common root causes of failure claims range from contractor error to design defects, mechanical failures and weather influences” … so basically everything is the most common cause of cable failures. Hilarious, there is no way these muppets will build a decent industry, not with management teams dedicated to profit and not investment.

    It is now 2023 A.D.

    THE TRUTH.
    The truth is that it is absolutely and irrevocably possible for honest, qualified engineers to calculate all costs and engineering parameters related to the design, construction and operation of wind turbines whether land or ocean sited.
    From this, a cost per kilowatt hour for delivering fully ready 240V 50 cycles per sec ac to local substations.

    THE SETUP
    This imposition on society has been a long time in the making and began many years ago when our state government, and I use the term lightly, deconstructed the integrated state power system into more profitable individual units looking after electricity generation, wires and poles and “marketing”. WTF.

    THE OUTCOME
    Australia now has perhaps the most expensive electricity in the world which makes our lives and futures grim and unpleasant. It is currently almost impossible to operate an office in Australia, let alone manufacturing of any daily use items that now pour in from countries overseas who have sensibly priced electricity.

    In hindsight, the collapse of Australia has been 50 years in the making and we have now arrived.

    The TRUTH according to our LEADERS;

    “Everyone now has a degree and we are the smartest nation in the world.”

    We have arrived! The land of Plonk and Worry.

    With a sensible Energy Policy in place, such problems would quite ‘sensibly’ be the responsibility (& cost) of the wind turbine operator (subsidy harvester, Carpetbagger).

    They should have every base covered to ensure ongoing power generation in accord with their contracted T’s & C’s (including back-up power generation of their own choosing / cost to ensure ongoing performance for what, after all, is an essential service) & a preparedness to meet substantial financial penalties in the event of any failure to meet their contracted QOS obligations.

    Easy… with a sensible Energy Policy in place!
