In order to comply with SI 1995 No 743, The Offshore Installations (Prevention of Fire and Explosion, and Emergency Response) Regulations 1995 it is a requirement for the Offshore Operator to prove compliance of all Temporary Refuges (TR) in accordance with this regulation.
In order to carry out these tests the module is pressurised using our Minneapolis Door Blower Unit. In accordance with HSE guidance notes 1/2006 an acceptable leakage on existing modules is 0.35 air changes per hour (ac/hr). On a new build module the acceptable leakage is 0.25 ac/hr. If leakage rates are above these levels Dynac’s Engineers will endeavour to identify where the leaks are using thermal imaging camera’s. Leakage will normally be attributable to badly fitting doors, worn door seals, fire dampers not closing correctly, transits not blocked off and leaking bulkheads.
All Dynac Engineers have been trained in carrying out these tests by BSRIA using the Minneapolis equipment.
Single TR Modules will normally take 1 day offshore to carry out and a multi -story complex will take 2-3 days.
