How do we close the gaps in piping test data?

We start by building the machine needed to generate it.

StressMan Engineering is developing Markl 2.0, a new modular physical testing rig in Norway. Our goal is to create a piping test center capable of generating valuable testing data for piping engineers, designers, and researchers. This machine marks the beginning of that journey.

In this webinar, we will present our early concepts for using the rig to test SIFs, SSIs, and flexibility factors for piping components.

Because the machine is modular, we intend to support a wide range of test configurations, including:

• Piping components
• Pipe supports
• Structural members
• Fl**ge joints
• Custom test setups

During the webinar, we will discuss:

• A short introduction to Markl’s approach: SIFs, SSIs, and flexibility factors
• The concept design of the testing rig
• Gaps we see in existing test data
• Opportunities created by Markl 2.0 and its modular test setup

The project is still at an early stage, so questions, ideas, and honest feedback are very welcome.

Good to see Stressman Engineering highlighted by Porsgrunn kommune.

From our office in , we work on engineering challenges that often sit far beyond what is visible on the surface, ensuring that critical systems perform safely and reliably in real-world conditions.

A small team with a global footprint, built on deep expertise and practical thinking.

🔧 På bedriftsbesøk hos Stressman Engineering i Porsgrunn
I dag hadde Porsgrunn kommune gleden av å besøke Stressman Engineering, som har hovedkontor i Lundedalen på Heistad. Det er et selskap som kanskje ikke er kjent for alle, men som leverer tjenester i verdensklasse – med utgangspunkt i Porsgrunn.

Stressman jobber med analyser og beregninger som sørger for at rør, konstruksjoner og tekniske løsninger tåler belastningene de utsettes for i praksis. Kort sagt: De hjelper kundene sine med å sikre at avanserte tekniske løsninger er trygge, robuste og fungerer som de skal.

Selskapet har 11 ansatte ved hovedkontoret i Porsgrunn og et høykompetent fagmiljø med solid ingeniørbakgrunn. I tillegg har Stressman ansatte og samarbeidspartnere i Oslo og flere andre land, blant annet i Italia, Latvia, Spania og Mexico. Kundene finnes innen energi, olje og gass, maritim næring og annen tung industri i Europa og internasjonalt.

Stressman Engineering ble etablert i Porsgrunn i 2010 og har siden bygget opp et sterkt internasjonalt orientert miljø, med tydelig lokal forankring. Et godt eksempel på hvordan spesialisert kompetanse og kunnskapsbaserte arbeidsplasser bidrar til verdiskaping – også lokalt.

Et selskap vi er stolte av å ha som en del av næringslivet i Porsgrunn.

How are SIFs, SSIs and flexibility factors from ASME B31J actually applied in real piping stress models?

On 24 March, our CTO Nikola Jacimovic, PhD, Eur Ing, and ASME B31.3 Code Committee Member, will lead a live online workshop explaining the practical application of ASME B31J in piping flexibility analysis.

24 March 2026
14:00 to 16:00 CET
Live online workshop hosted by EngineeringTrainer

This session is intended for engineers involved in piping stress analysis and flexibility assessments according to ASME B31.3.

During the workshop you will learn how to:

• Understand B31J SIF and SSI formulations and flexibility factors
• Quantify the effect on sustained and displacement stresses
• Apply SIFs and SSIs at the correct model nodes
• Recognize common B31J modeling pitfalls in software
• Derive factors using shell and brick FEA models
• Interpret FEA results using the twice-elastic-slope concept

The workshop focuses on how B31J SIFs, SSIs and flexibility factors are implemented in piping stress models and how they influence flexibility and stress results in real piping systems.

One foot in the classroom. One in a hard hat.
That transition from student to professional can feel like a lot.

That’s why we’re heading to Karrieredagen 2026 at the Universitetet i Sørøst-Norge - USN, Campus Porsgrunn, to have real conversations, not just collect CVs.

Stop by our booth to talk about what we actually do, and join the mingling event we’re sponsoring.

Why stop by?

• Talk with StressMen and StressWomen who do the work every day
• Join the mingling, Marlene Stavrum will keep the mood light
• The StressLorean (yes, the car is real)

No pressure. Just good vibes and straight engineering talk.

Fifteen years. Infinite possibilities.

We've spent over a decade turning complex challenges into precise solutions; each project pushed us further, and each innovation opened new doors.

Here’s to the visionaries who trusted us, the team that makes it happen, and the future we’re designing together.

In this talk, Sondre Luca Helgesen, CEO of Stressman Engineering, sits down with Luuk Hennen, CEO of EngineeringTrainer , to address a critical topic: “Beware the Frankenstein Hybrid in Engineering!”

The concept of the “Frankenstein Hybrid” comes from the idea of assembling parts that were never meant to work together, like the fictional character created from mismatched pieces. In engineering, this metaphor warns about the risks of combining tools, systems, standards, or processes without a clear strategy, understanding or proper integration. What may appear intuitive for one engineer without deep knowledge of a engineering discipline can quickly become overly conservative, inefficient, costly, or flat out incorrect and dangerous.

Sondre emphasizes the importance of coherent design and understanding the lingo of the various engineering disciplines.
