Challenging Industry Norms in Advanced Pipe Stress Analysis and Structural Engineering
Stressman Engineering AS is a Norway-based engineering consultancy specializing in advanced pipe stress analysis, pressure vessel calculations, and structural integrity assessments for high-demand industries including oil and gas, aquaculture, energy, and maritime sectors.
Founded in 2011 by mechanical engineer Sondre Luca Helgesen, the company was established with a clear ambition: to challenge conventional engineering methodologies and deliver higher value to clients through deeper technical understanding and integrated optimization. With a core background in pipe stress engineering, Stressman recognized early the limitations of siloed engineering disciplines. By combining expertise in piping systems, supporting structures, pressure vessels, and rotating equipment, the company developed a more holistic and performance-driven approach to mechanical design and analysis.
Advanced Engineering Calculations Beyond Conventional Methods
Stressman Engineering is known for its ability to operate both within and beyond established industry standards. The company maintains strong expertise in international design codes and regulatory frameworks while actively contributing to the evolution of engineering standards. This dual competence enables the team to perform complex and non-conventional pipe stress calculations that remain fully compliant with safety and code requirements.
By focusing on first-principles engineering and a deep understanding of physics, material behavior, load cases, and boundary conditions, Stressman solves technical challenges that often exceed the capabilities of traditional engineering firms. Their methodology integrates:
Detailed finite element analysis (FEA)
Advanced pipe stress simulations
Structural interaction analysis
Pressure vessel and high-pressure component assessment
Multidisciplinary optimization of piping and support systems
This knowledge-based and research-oriented approach ensures technically sound, cost-efficient, and optimized solutions tailored to each client’s operational environment.
Engineering Quality Control and Academic Collaboration
To strengthen its technical foundation, Stressman Engineering brought in academic expertise through collaboration with Professor Mladen Jecmenica from the University of South-Eastern Norway. This partnership reinforces internal peer review processes, quality assurance systems, and engineering validation procedures — particularly important for a company operating at the intersection of applied engineering and research.
Internal technical control, side-by-side verification, and structured quality checks are integral parts of the company’s engineering workflow, ensuring high reliability and traceability in all calculations and simulations.
Diversification and Sustainable Growth
Originally focused on oil and gas projects, Stressman Engineering strategically diversified following the industry downturn of 2016–2017. Today, the company serves multiple sectors, reducing market vulnerability while expanding its expertise into new industrial domains.
With 17 employees and recipient of the 2025 Gaselle Award for rapid and sustainable growth, Stressman Engineering has established itself as a knowledge-driven and innovation-oriented engineering partner.
Developing Testing Methodologies for Modern Piping Systems
Modern piping systems operate at higher pressures and temperatures and increasingly utilize advanced and exotic materials. Many existing piping standards were developed in the 1950s and are based on testing of standard wall thicknesses and conventional materials. Today’s thicker-walled components and complex geometries present new testing challenges.
Stressman Engineering is actively developing improved physical testing methodologies for pipe components to better reflect real operating conditions. In parallel, the company is investing in new internal AI systems to enhance engineering workflows, simulation efficiency, and data-driven decision-making.
A Culture of Technical Curiosity and Continuous Improvement
At the core of Stressman Engineering is a culture that encourages engineers to challenge established processes, test new ideas, and continuously improve calculation methodologies. Proposed improvements are evaluated through parallel method validation, ensuring that innovation is always balanced with technical robustness and compliance.
By combining deep technical expertise, advanced simulation tools, code compliance knowledge, and a willingness to challenge industry norms, Stressman Engineering delivers high-value engineering services that enhance safety, performance, and cost-efficiency for complex industrial projects.
