Welcome to Onsala Ingenjörsbyrå AB 

Your partner in advanced structural and fluid calculations


With a history of over two decades in the Swedish nuclear industry, we have a long record of projects carried out for the nuclear power plants Ringhals, Oskarshamn and Forsmark. See our references.

With high-end resources in both software and hardware, combined with experience and continuously educated personel, we are able to perform highly advanced projects in-house, in our office in Kungsbacka, Sweden. We work with fracture mechanics, vibrations caused by flow fields, fluid-structure-interaction (FSI), thermal-hydraulics, collapse, thermal mechanics, water-hammer analysis, large and small effects of LOCA (Loss of cooling accidents) including FSI and we have long experience in structural verification projects of RPVs and internals of BWRs including fatigue analysis with the option of including environmental factors of the coolant and materials, etc.

You will find more examples under "our services" or check out our references where you will find examples of our track record and please feel free to "contact us".
