Video

Excellent content here. Every insurance risk engineer involved in renewable energy risks should watch this!

Very easy to understand! Good information! I will watch again to reinforce learning. Thanks Chuck Worrell FireSafetyConcepts

14:45 what a nightmare, I hope you all had the proper LOTOs in place! Who would guess the janitor would pull the power, not realizing the open vessel...

This was great--thank you for sharing your industry experience!

This is some incredible content. So interesting to see high quality overviews of other engineering disciplines.

Hi John, thanks for another interesting video. What shall be the priority of recommendations like inspection related item first or management system related or hardware related changes ?

Great video and explanation! Reach out to Hose Monster if anyone has questions on how to perform a test.

Thank you. Excellent thinking to determine that is the one leak. Regarding brittle fracture or fatigue fracture in my opinion it doesn't matter. Such a failure and the resultant claim occur when it is discovered. That can be the time of the noted leak or when a piece of equipment is opened for inspection. I have seen that line of thinking held up in court in Canada, the UK, and the USA. Please keep these videos coming.

Pretty good video. Appreciation from Brazil

I test a fire pump that consistently has a high churn pressure (140 PSI plus as compared to the factory churn of 116 PSI) The 100 % is always around 90% of the factory 104 PSI at 94 PSI and then the bottom falls out at the 150% point (Factory at 87PSI to the annual test pressure of 58PSI which is well below the 90% requirement). This is a vertical turbine pump with a raw water source. Normally I get a -3PSI for the supply pressure as the water level is usually around 6.5 ' from the surface of the water to the C/L of the discharge on the pump. The curve on the graph is always convex instead of concave. Would you be able to direct me to a corrective coarse of action that would help resolve this. The pump rating is 1,000 GPM @ 104 PSI with 1770 RPM. My RPM readings are around 1785 at churn, 1777 at 100% and 1774 at 150%. Yes, I do have my gauges calibrated annually.

Great info! Question about the flange guards, Should they be a FM approved?

Thanks that was amazing. Can you please make a video on what an insurer should look for a thermal power plant which is under preservation.

I really appreciate it. This videos are so good. Greetings from Colombia.

I'm new to Risk engineering. Thanks for sharing very informative things here on your channel.

Thank you. This is a growing area and much information is being shared especially on LinkedIn and industry publications. Those involved in these systems need to be following those areas to key up to date.

What if corrected test result shows that test curve is above the pump OEM curve...what is the interpretation for such result? will 5% apply to going above the OEM curve as well?

Great video and good points. A few thoughts: - wind stow should not be flat. Flat panels will catch the wind like an airfoil and develop oscillating motion (torsion on the tracker torque tube). This leads to galloping - look up a couple decent losses from a big name tracker OEM in Australia that occurred well below design wind speed. So even though it's counterintuitive, wind stow is now usually designed the same as hail - fixed at max angle. This is still debated from the perspective of windborne debris, but with significant windborne debris you are going to have a bad day no matter what. - checking for debris that can become windborne missiles (both on property and neighbouring properties) is a good idea on loss control surveys. - vegetation management is the key for wildfire mitigation. Glass-glass panels (usually bifacial) are a little more resistant. Fire response plan is actually really crucial, because close coordination is required with utility staff to keep responders safe from electric energy hazards. Some owners use various other strategies including long-duration biodegradable fire retardants applied around solar farm perimeters during fire season. - for microcracking, the only global OEM of thin film panels (First Solar) claims they are immune to microcracking, and have pretty compelling data, explanation, & policies to back it up. It's probably not enough to change procurement decisions, but definitely something to highlight. Finally - I love your thoughts on 2x 66% capacity step-up transformers. It's an approach I also endorse and recommend. With the capacity profile of most solar plants, a single 66% capacity transformer is usually enough to capture >85% of revenues!

very useful explaination

If one is to use animals for vegetation management one can't use goats. As you noted not only will then eat everything including wires they will also climb onto panels. Sheep are the way to go as they don't climb and limit their eating to grass. I have seen a few sites with successful sheep operations.

The only time I would apply affinity would be with a variable speed controller (VFD-PLD) because speed is what i is but also how well the mfgr matched the driver to the pump.

Great insight sharing for engineer society. Keep doing sir.

Thank you for the account. Wow. Bypass a permissive on the crane and then create an impairment on the AS. Hmmm so much for the nuclear safety cornerstones of strict adherence to procedures and conservative decision making. I hope you do a video on the plugged toilet that caused a 400 MW coal fired boiler to blow up in MO.

Yes there isn’t an exclusion for mistakes. If there was most claims wouldn’t get paid. The Engineer who wrote that report needs to learn what Sudden and Accidental means for a machinery breakdown claim.

Thank you. Excellent points. I assume that there was no BI cover for this generating station. The flammable liquids behind you need to be stored in a UL rated cabinet, AS added to the combustible structure, and please confirm that the exterior lightning is connected to a GFI outlet. 😉

Thank you. When you said they wanted to consider it wear and tear I laughed. That wasn't wear and tear. Good move not arguing over $20,000.

Excellent video thank you.

I haven’t watched the video yet but I’m going to guess a GE, now ABB, Type U bushing made in the 🇺🇸. The 🇨🇦version doesn’t have same paper insulation issue.

A great Explanation thank you.

Excellent information, under COP28 a number of counties pledged to invest over a trillion dollar by 2030. I am also planning to further pursue PHD in Clean Hydrogen Technologies especially around the production of affordable sodium borohydride (NaBH4) as a hydrogen carrier.

Intresting

This may be the best and most effective explanation of risk around and I've borrowed from John's presentation for my own presentations. Thanks, John.

Insightful, nice logo

Your lube oil video was condensed, clear, and packed with knowledge. Thanks to you

A great explanation. The only thing to add is that the fire pump alarm signals and controller functions must be tested as well per NFPA 25. Almost no one does that.

Thank you sir.

This was really amazing,

Thank you. Every plant should watch 😅

Very informative 👍

Excellent content and kudos to the hard work you put in, I can guarantee that your channel will grow and surely be the best in the Engineering Risk Management Industry!

Excellent and very informative👏👍, thank you so much for sharing it. Really interesting to understand risk perception and factors affecting psychological and behavorial aspects of it. It is extremely important that one understands that the risk tolerance level and appetite differs from person to person and it plays a significant role in evaluating risks.

Wow! Thank you for the thoughtful questions. The make and model of Gas Turbines especially is important as they are all generally still research projects when they are built. Mechanical issues can be model specific. There are certain large power transformers that may have design defects. As for the Halon system. We had a $50K protection system for a $10K building. Refilling the Halon would cost more than burning down the little building. When we have a useless system, it doesn’t matter if it works. It should have been removed. Thanks again for the input. Would you be interested in me interviewing various Risk Engineers to find out how they got started and what they like about Risk Engineering?

Hi John I am a junior Risk Engineer working in the UK. I thanks you for sharing the video & kudos to you for making such content. I had a few questions though: 1. Why make & model of equipment are required by the underwriter ? I mean a transformer or motor capacity is enough with records to show periodic maintenance. Since the equipment is being used in a factory, it will be from a standard company (reputed/reliable brand). We can always highlight if something is non standard but mostly people dont cut corners with such equipment 2. The European Engineers fire door insight, was he not wrong that the halon would not work as intended due to the lack of pressure with open gate. I can get back to you on this. A few of the pitfalls I have been part of, while I was working in India: Unorganised inspection with poor coordination. I once went in a visit where 4 other Engineers were expected, apart from myself. When I was about to complete the inspection, I crossed the other group which had arrived at a different time & with other site contact altogether. So yes these things does happen.. 2. During my meetings, I used to call a person from health & safety, maintenance & production so that any requirement could be coordinated. PS: Thank you once again for the video. I was trying to message you on LinkedIn (request pending) but I could not due to lack of premium subscription.

Thank you

Thank you very much for the videos. Please, don't stop doing this. I just started my career in risk engineering and the videos are just the perfect learning path for me.

Great video series thanks! Can we have a video on risks associated with renewable power assets ie wind, solar, battery etc

Do the transformer core also have internal temperature F.O. sensors? If they have core temperature detection, why is external detection for deluge actuation? Rather than heat detection or LHD?

Awesome video 🎉

Your videos are really good... Thank you for such wonderful and useful videos.

Is the tracking of fire pump performance over time always a linear degradation? Does that % of degradation accelerate over time, does the pump get to the point in it's lifetime where as the pump gets closer to it's life need more frequent testing?

What are the typical schedules for travel like for a broker engineer. I understand there's a lot of travel, but how much in a month or week?
