APPLICATION
Our TR-unit basically consists of an explosion proof fan, a filter section that filtrates H2S & SO2 and optionally a heater. The power supply is coming from the vessels Uninterrupted Power Supply (UPS) system or optionally by a battery power pack to ensure operation at all times.Our TR unit provides clean filtered fresh air, free from H2S & SO2 contaminates in an over pressured Temporary Refuge area. Three levels of filtration (G4, F7, and active carbon) is applied to incoming air before being supplied to the TR. The control system constantly compares inside and outside pressures and LEL’s, and should the TR area pressurization or LEL levels fail, provide a visual and/or audible warning.Our TR unit is designed for external installation to TR areas with a supply duct to the TR area interior. The TR unit control panel is designed to be installed internally within the TR area. When the TR unit is operational the unit is designed as a fail-safe system, i.e. should the unit sustain damage or an air seal leaks, then clean air will leak out of the unit rather than contaminated air being drawn in.During normal operation is the TR unit “dead” and closed by gastight dampers. It comes operational for emergency situations.
INTRODUCTION
The Cullen Report into the Piper Alpha disaster (Cullen, 1990) recommended that a temporary refuge (TR) should be provided on all offshore installations. The TR is required to have a defined performance standard related to its survivability when exposed to a major accident that includes, but is not limited to, ingress of smoke, flammable and toxic gas. HVAC forms an essential part of this. As the TR is the last space for the crew before abandoning the vessel, rig or platform, the HVAC system should create and maintain a comfortable and safe indoor condition free of any explosive and/or toxic gas-air mixtures. The air quality and pressure inside the TR-zone is than of top priority. This can be created by our special TR pressurization unit (TR-unit).
