Thanks for all you've been doing, risk engineers should do more of this.

Thank you. Good advice. Yes recommendations should be clear and detailed so the plant knows what to do. I have seen my share of recommendations that say, ‘Improve XYZ’ but give no details on what that improvement should be.

thanks much for this enlightenment... its really interesting

Are there any recommended references?

Very good video that taught us a lot

Gem of a Video ! Surprisingly, the level of engagement your posts receive on LinkedIn, is not reflecting here.

I am a big fan of fossil fuel. How about we use that until we get a real solution?

Great video! I also suggest to check NFPA 850 chapter 19. Thanks again John.

"As long as we can reach the other side" Very " local" interpretation of code intent! ❤

trying to become a risk engineer in toronto canada. Im in my final year of my advanced diploma in fire protection engineering technology

Great!! Can you share information how you calculated the cost of risk for not completing a recommendation?

Thank you. I hope you will continue to please us with your new videos

Thank you. That was great. I have not explored AI yet and this helps point me in a direction.

Another excellent video. Thank you. I’m referring this and others to my newer consultants as training material. You quite nicely say many of the things I would say and more.

Thanks for the great video. Where can we find the data and tables around the heat flux and damage observed?

This is an amazing presentation video John on alarm management - watching this 2nd time. Is Alarm rationaalization & Alarm Bad Actor Management are same ? or Subset ?

The NTSB had in one of their Railroad Accident Reports stated where a locomotive engine had a piece of tape over the excessive speed alarm in the cab. Excessive speed was a factor in that derailment. Alarm overload! Glad to see this addressed. I did semiconductor wafer processing, and, some of the automated process machines had levels of alarms that could be set. The blue level alarms reported ever thing the machine did, even though those were normal events, I preferred to disable blue level alarms, to prevent alarm fatigue. But, I've heard of pipeline SCADA systems that would generate dozens of alarms per hour, causing alarm overload.

Well explained.

I would love BESS and hydrogen-specific videos for your renewable videos! Love the content sir!

Amazing Video on Risk Engg Survey in Chemical/ energy.

I think insurers and other stakeholders should come up with a recommended distance between two strings which has to be maintained to avoid all strings catching fire from nearby strings. Apart from that heat/smoke sensors must be there under panel/string which can activate fire extinguishers or Medium velocity water sprinklers.

Several things come to mind: The dying batteries reminds me of a semiconductor fab I worked at. There was backup power for machines that were processing multiple wafers at the same time, power glitches would kill the wafers. Well, there was a phase variance in the commercial power, causing the fab to disconnect from the grid. But, the backup power didn't come on, since it sensed that the commercial power was still available, ignore the phase issues. So, millions of dollars of wafers lost. Risk factors reminds me of an consulting Geologist for a BC Canada LNG project being unaware of the Cascadia subduction zone, which causes monster earthquake ever few centuries. Then, the 2012 Chevron USA Richmond CA fire. A pipe had been patched like 50 times over the years, failed, 16 people were in the vapor cloud, but got out before it ignited. Multiple patches should have been a red flag to replace the pipe with more corrosion resistant material pipe.

Not knowing the upper & lower limits of the processes? Sounds like the big BP America Texas City TX Refinery, which had that massive, fatal explosion of 2005. Worth a look at the USCSB video, for any out there not familiar with that. Loss of maintenance records? I've been aiming at pipeline safety, and, records of maintenance is critical for pipeline safety. Bad batches of pipe, repeat external corrosion, due to corrosive soil, or bad coating, etc., can be caught this way, but some companies feel such maintenance records are useless. The untrained workers reminds me of " An explosion on July 8, 1977 at Trans-Alaska Pipeline System Pump Station No. 8 killed one worker, injured 5 others, and destroyed the pump station. Over $2 million in damage was done. A US House of Representatives Committee later announced the cause was workers not following the proper procedures, causing crude oil to flow into a pump under repair at the time." Brand new pipeline at the time. Alarm clearing: It reminds me of an incident in "Inviting Disaster", by James Chiles. A worker at a power plant control room clears an alarm on the SCADA very quickly. An Executive touring the area at the moment asked what the alarm was for. The worker didn't know what the alarm was, the habit was to just clear alarms.

Americans will use anything but metric.

Was this filmed with a potato?

Interesting. I know of some people living near LPG/NGL pipelines, and the pipeline company is being cagey about how far away to evacuate, & how big a vapor cloud fire can be. They plan for first responders to go door to door to evacuate people, with the likelihood they would be in the vapor cloud. Since this is a mostly suburban area, ignition prevention can be a real issue, I know of some LPG pipeline failures, where the ignition source for the vapor clouds was never found. Also, the intentional ignition of vapor clouds bring to mind the conditions present. A leak in a propane pipeline in Missouri in 1970, in a weather inversion, detonated.

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.
