It counts the records in this register that name this company in any role. Being named is not a finding of fault. Most incidents have several contributing causes, and the company named as manufacturer, integrator, operator or contractor is often not the cause of what went wrong.

If you work for this company and something here is wrong, tell us and we will correct it. Use the corrections page: we acknowledge within 2 working days and decide within 10.
