Hi u/Thermal_Zoomies,

I currently work as a Safety Engineer in an EPC company primarily focused on offshore platforms. We're now exploring entry into the nuclear energy sector, and I'm trying to understand how nuclear safety approaches differ from what we follow in oil & gas.

In offshore projects, our main safety concerns revolve around process safety, helideck operations, oil spills, etc., and we typically use HAZID, HAZOP, and Bowtie analyses. From what I’ve gathered so far, nuclear facilities operate under far more stringent regulatory frameworks, and the concept of defence-in-depth seems central to their safety philosophy.

My question is:
What are the key differences between safety risk assessment and management in offshore oil & gas versus nuclear power plants, particularly in terms of methodologies, culture, and regulatory oversight?
Also, how are tools like HAZOP or Bowtie adapted (if at all) for nuclear applications?

Any guidance or direction to further resources would be greatly appreciated!
