As well as working for the petrochemical industry, we also service renewable power installations such as wind farms.

Temporary Refuge (TR) Integrity Testing

We provide detailed, PFEER-compliant* reports on the integrity and leakage values of temporary refuges for offshore petrochemical installations.

Our thermal imaging equipment and other tests can reveal TR impairments including:
⦁ Bulkhead corrosion and transits
⦁ Door seal impairments
⦁ Duct corrosion
⦁ Fire dampers
⦁ Untrapped drains
⦁ Window seals

* Prevention of Fire & Explosion & Emergency Response ‘PFEER’ Regulations (1995)

The Offshore Installations (Prevention of Fire & Explosion & Emergency Response ‘PFEER’ Regulations 1995) places a duty on Offshore Operators to demonstrate compliance of all temporary refuges (TRs) in meeting acceptable air leakage standards.
