Solutions that work together
We manage functional safety. And we equip the people who deliver it.
ROAK Engineering are functional safety management experts for functional safety projects. Around that core, our software, templates and community fill the gaps — supporting the engineers and teams doing the work, at every stage.
Independent functional safety authority
Get functional safety right at the right time. Expert guidance for your engineers, plus independent assessment when the project needs it — as much or as little as it calls for.
TOOLS FOR THE ENGINEERS DOING THE WORK
SILVerify
Know your SIL calculations are right — and prove it. Verification software that removes the spreadsheet risk for the engineers doing the work.

Big consultancies assign whoever's free and rotate them off when it suits. ROAK is one named, certified functional safety expert — CFSE, TÜV, 20+ years in nuclear and defence — who's sat on the assessor's side of the table. Hands-on with your engineers where it matters, and honest with you about where things actually stand while there's still time to act.
Proven impact
Real outcomes for real projects.
We partner with organisations where safety is critical and failure is not an option.
View case studies“Richard has been my main Safety Instrumented Systems consultant during the delivery of a number of significantly complex nuclear and explosive handling projects. He will identify and directly challenge any person or organisation, no matter how confident they are or reluctant they are to comply. He is excellent in this field and he has never let me down.”
