The 300 Year Party
Published: August 2021
Imagine taking a magic carpet ride through northern Europe from east to west in Biblical. The area is circled on the map shown below — an area that Ugo Bardi rather unkindly refers to as a "vast regions of fog and swamps, inhabited by hairy Barbarians . . . the area we call today "Western Europe".
You would fly from what is now western Russia, over the Ukraine,…
Hyperloop Generic Safety Study
In Safety Moment #8: “But We’re Different, You Know” we show that risk analysis techniques have much in common across different parts of the process and energy industries. Lessons can be shared across industries such as oil refining, chemicals manufacture, pipeline operations and offshore oil and gas production. But, given that the first word in the phrase Process Safety Management (PSM) is…

The New PSM Normal (2) — Do Less With More
Dateline: June 2020
Update: August 2021
The COVID-19 pandemic has changed everything. When more than 22 million people in the United States alone lose their jobs in just a few weeks we have entered a new and different world. There is no going back to an ‘Old Normal’. In the first post in this series, The New PSM Normal (1) — Deflation, I suggest that we are entering a time of deflation, which…

A Kodak Moment for the Oil Companies
The term “Kodak Moment” originally referred to a rare or special occasion that was captured on (Kodak) film. The term has also come to describe a situation in which a company fails to foresee structural changes in its industry such that the company eventually falls into bankruptcy.
The Kodak company was a world leader in film photography. Management of the company understood that digital…
The New PSM Normal (3) — Peak Oil
This post is the third in a series in which we consider how our approach to industrial safety, and process safety in particular, may change in response to the COVID-19 pandemic. It is early days — no one knows what the ultimate health and economic effects of this frightening event will be. But it seems likely that we are entering a ‘New Normal’. So much has happened so quickly that it is hard to…
The New PSM Normal (4) — Automation
If you fly over the offshore platform of the future in a helicopter and look down you will see just two living beings: an operator and a dog. The operator’s job is to feed the dog; the dog’s job is to make sure that the operator doesn’t touch anything.
This is the fourth post in our series to do with the ‘New Normal’ as it applies to industrial safety. The series is written on the assumption…
The New PSM Normal (5) — Standards
2020-05-20
In this post I would like to consider how those of us who work in industrial and process safety can help the community at large? The subject came to mind when I was discussing the eventual return of people to church services with a colleague. Our Episcopal diocese has organized a four-phase program for the re-opening of the churches (we are currently in Phase One).
Phases Two and…
The New PSM Normal (7) — Things Feel Different
2020-06-03
In the post SEMS and Risk in 2020 (SEMS if the offshore equivalent of process safety management as applied to U.S. deepwater operations — mostly the Gulf of Mexico), Mick Will, says,
The speed with which drastic change has come over our industry is what is so different from past events. While oil price volatility has been something I have dealt with for 42 years, I do not remember…
Pig Launching and Retrieving
This article provides guidance to do with the launching and retrieving of pipeline pigs (also known as scrapers or tools).
Pig Launching
Below is a schematic of a launcher.
In normal operation the fluid (liquid or gas) moves along the line from left to right through the open Main Line valve. The kicker and isolation valves are both closed hence the barrel of the pig launcher is isolated from…

The Shape of Net Zero (1): No Substitute
As good as it gets
This is the first article in a series to do the future of energy in a Net Zero world. In this article we look at fossil fuels, why they are so valuable, and the properties they have that will make them so difficult to replace.
Many of the discussions in this series are based on the following sketch. We will review and analyze sections of this sketch in future discussions. For…
The Renewable Energy Paradox
Renewable Energy. M.C. Escher's Waterfall (1961)
The Paradox
Renewables are growing faster than other sources of energy.
The fraction of energy provided by renewals is declining.
The Net Zero Commitment
At the heart of most ‘Net Zero’ programs lies a commitment to transferring our primary energy sources from finite fossil fuels (coal, oil and gas) to renewables, which, in practice…
Nine Pounds of Gold and Peak Oil
What this NOAA article is saying is that it is not the absolute amount of a resource that matters — it is our ability to extract it economically. In the case of gold, it is highly unlikely that it will ever make sense to extract if from the sea. It is simply too dilute. So much for this “get rich quick” scheme.
With regard to gold, it really doesn’t matter how much the extraction process costs…
Alice, the Red Queen and ERoEI
Faster! Faster!
In Lewis Carroll’s famous story Through the Looking-Glass the protagonist, Alice, meets the Red Queen. Suddenly they start running.
Alice never could quite make out, in thinking it over afterwards, how it was that they began: all she remembers is, that they were running hand in hand, and the Queen went so fast that it was all she could do to keep up with her: and still the…
Greenhouse Gas Emission Scopes
The matching YouTube for this article is located at the Greenhouse Gas Emissions Scopes video.
Many companies in the energy and process industries have committed to a Net Zero program. Their aim is to cease net emissions of greenhouse gases by a specific year, often 2050. In order to properly define their goal these companies need to identify the emissions for which they are responsible.
The U…
The Future Has No Narrative
The following is a short summary of the full post, The Future Has No Narrative.
In 2015 the author Wendell Berry said,
So far as I am concerned, the future has no narrative. The future does not exist until it has become the past. To a very limited extent, prediction has worked. The sun, so far, has set and risen as we have expected it to do. And the world, I suppose, will predictably end, but…

Hard Times for These Times
Dateline: August 2021
Story-Telling
Most of the people reading posts such as this are aware that earlier this month the IPCC issued an alarming report on climate change that should make society change its ways. Failure to do so could lead to catastrophe and a possible breakdown of civilization within just 20 years. Yet nothing happened; the report changed almost nothing. It was just a blip in…
The Shape of Net Zero (3): Refinery Operations
August 2021
This is the third post in the series ‘The Shape of Net Zero’.
The first post was The Shape of Net Zero (1): No Substitute. Its theme was that is really no substitute for fossil fuels, particularly crude oil. Fossil fuels are economical, safe, environmentally clean (particularly as compared to nuclear), energy dense, always available (dispatchable) and portable. They are also an…

The company makes it clear that they are not predicting the future. The report’s purpose is to outline how energy consumption and…
Industry Leadership
Shown below is a summary of the post Industry Leadership.
In the post Net Zero: The Business Opportunity we saw that many businesses have adopted a ‘Net Zero by 2050’ strategy. This means that these organizations intend to have ‘net zero’ emissions of greenhouse gases by the year 2050. One way — and by no means the only way — of achieving this goal is to develop and adopt new technologies that…
The Shape of Net Zero (2): Alternative Energy
The good old days
This post is the second in the series ‘The Shape of Net Zero’. The series is based on an understanding that we cannot simply switch out one source of energy (fossil fuels) with another (wind, solar, nuclear and others) and carry on with Business as Usual. We need to consider the following parameters to do with a switch in the basics of our energy supply.
Fossil fuels,…
Realities: Nuclear Power
A theme of the posts at this site is that we are awash in good ideas, but many of these good ideas cannot be scaled up quickly enough to have a meaningful impact on the climate crisis. This post — Realities: Nuclear Power — illustrates this conundrum. Nuclear power is an established energy source. It has its detractors, but it is established and known to work. However, if nuclear is to provide…

Systems Completion, Commissioning and Start-up
Did you know that from the perspective of an investor, it is the Commissioning & Start-Up (CSU) phase that defines the project as a success or failure? When a project has been fully commissioned and started-up, it is likely the project will also be a financial success, with investors receiving their expected returns. When a project has not been fully commissioned and is then started-up, it is…
Safety and Environmental Management Systems (SEMS)
Overview
Following the Deepwater Horizon/Macondo catastrophe in the year 2010 it became clear that substantial improvements were needed to offshore safety management in the United States. The framework of a new rule was already available as API RP 75 - Development of a Safety and Environmental Management Program for Offshore Operations and Facilities (SEMP). This standard was used as the basis…
The Case for Safety Cases
The Deepwater Horizon/Macondo catastrophe in the Gulf of Mexico (GoM) in the year 2010 demonstrated the need for new safety management regulations.

The New PSM Normal (6) — Alternative Energy Reality Check
2020-05-27
I would like to take a break from talking about this virus this week. (Wouldn’t we all?) Instead, let’s take another long-range look as to where the process industries may be going, and how safety management programs may have to adapt.
There is much talk in the oil industry to do with the current low oil prices and how the loss of revenue will lead to a cutback in investment,…
Event Tree Analysis
Overview
Event Tree Analysis (ETA) uses the same logical and mathematical techniques as Fault Tree Analysis. However, whereas a fault tree analyzes how an undesirable top event may occur, an event tree considers the impact of the failure of a particular component or item in the system, and works out the effect such a failure will have on the overall system risk or reliability. Event trees use an…
