The Art of Working Properly

Company belief!

Safepark believes, that process safety is the art of working properly. Working properly means taking a scientific approach to solving your health, safety and environmental (HSE) challenges. Art is finding a common sense basis in your company culture to achieve the ultimate goal of process safety: That everyone are certain to return to loved ones at the end of a workday without injury.

Is Grindsted the Danish Love Canal?

On June 20th this the Danish weekly newspaper “Weekendavisen” (link to Danish language website of the weekly) published a report by freelance writer Jakob Jensen called “Alas, how changed!” (link to Danish original behind paywall). When reading Jakob Jensen’s report about this town in the middle of Jutland, I started thinking about the Love Canal dumpsite at Niagara Falls, USA. Read more about the pollution at Love Canal her. I could not stop speculating whether Grindsted the Danish equivalent of Love Canal?

Grindsted is a city of about 10,000 inhabitants about 60 km from the west coast of Jutland. One of the larger employers of this town is a chemical factory, which years - with the approval of the government - dumped chemical waste containing chlorinated solvents, heavy metals, cyanide, mercury on at least four different sites in the city and also at Kærgård Klitplantage. In the city the material seeped into the creak, and at Kærgård it seeped into the North Sea.

Read some excerpts of Jakob Jensen's report from Grindsted here, and judge for yourself is my headline is correct or not. Send any comments to niels.jensen@safepark.dk . Maybe I should also just forget about the past an move on?

Needless killing of many people

WSJ reports death toll rises to 85 people

Oil industry image suffering - ones again!

Post Date Jan 20, 2019 10:40 AM

The Guardian reports, that more than 70 people were killed and more than 70 people injured in the explosion at a Pemex pipeline in Mexico. Appearantly fuel theft is a major problem in Mexico, and the people don't understand that it is extrimely dangerous to get covered in liquid fuel, which happened to many people while they were stealing petrol from a leaking pipeline. There is speculation, that in this event the thives actually cut holes in the pipeline.

Pipelines are difficult to protect as they run through uninhabited areas for many miles, and often are not burried. However, it appeas the Pemex - and not just the Mexican government - has a major educational need to educate the general public about the dangers of cutting holes in pipelines and stealing the content.

Unfortunately this is another nail in the coffin of the oil industry, which I years ago were very proud to work in. The negative effect of an explosion like this one goes beyond the company involved. It has impact on the whole industry, and especially the construction of new piplines, which are otherwise one of the safest ways to transport liquid fuel over large distances. It also seems the many negative events at Pemex during the past ten years indicate, that process safety is an afterthought in that company. So I think the question is how can industry internationally ensure companies make pipeline safety a priority?

  • Use of Dow's Chemical Exposure Index during site selection and initial conceptual plant design. Dow's Chemical Exposure Index can help evaluate the impact of your facility on the neigboring community. We have teaching experience from a major university.
  • Use of Dow's Fire & Explosion Index to create safer plant layout. Dow's Fire & Explosion Index can help you create layouts, which avoids or minimize domino effects in plants and tank farms. We have teaching experience from a major university.

About our owner

Niels Jensen is a retired professional engineer, who has extensive experience with process safety and process control in chemical plants and laboratories.

Before starting Safepark Niels had a rewarding career as teacher and safety leader in academia improving students understanding of process safety, and as process control leader in the chemical industry implementing multivariable control based on both laboratory and online measurements on reactors and distillation columns.

Niels is available to facilitate your process safety improvement project or for private consultations on process safety. You can reach Niels at +45 4141 5531 or niels.jensen@safepark.dk.

From the summer of 2008 until early 2018 Safepark has been part of a group encouraging developments in Multilevel Flow Modeling (MFM), which is a rule base technology for modelling industrial plants for reasoning about their states. Your can read more about MFM on mfm.safepark.dk . Niels have published papers about use of MFM during a HAZOP study and about MFM usage in alarm design and response to alarms. Some of these are featured below.

Two of the potential uses of MFM is in HAZOP analysis and in alarm design, as described in the articles below. However, MFM is not limited to be used in such operational tasks, but could also profitably be used in the development of a chemical plant design, from concept to start-up.

Recently Niels co-authored together professors emeritus Sten Bay Jørgensen and Morten Lind titled "Functional Modeling View on Product and Process Engineering in Design and Operations" in Industrial and Engineering Chemistry Research DOI: 10.1021/acs.iecr.8b06338
