Challenges in Halon Replacement at Offshore Fields

Fire & Gas

Ibtihaj Jaber AL-Menther

Abstract: In the early 1980s, it was confirmed that the earth’s ozone layer was being depleted. Although it makes up a small percentage of the atmosphere, the ozone layer is nonetheless essential to all living things. Located mostly in the stratosphere, the ozone layer protects us from the sun’s ultraviolet medium wave (UVB) light, which can be harmful to humans (can be a factor in skin cancer), crops, and marine ecosystems .

As per Montreal Protocol ,Halon clean agent is considered as an ozone-depleting substance and mandated that they be replaced with a commercial alternative.

The existing Halon fire extinguishing systems at ADMA-OPCO facilities are under replacement with environmental friendly extinguishing system as part of company & government/ international regulation.

Each facility replacement is evaluated based on HSE study , business and structural Risk.

During EPC stage, careful methodology & Risk Assessments are considered with modifications to the existing electrical, instrumentation, piping, HVAC and structural facilities, as potential risks are associated with decommissioning of existing Halon system, engineering/operational interfaces with ongoing projects as well as schedule constraints for safe removal/replacement of Halon systems.

This paper deals with the challenges and methodology adopted for a Brown field project to ensure a 30 year old Halon system spread across more than 200 locations are safely decommissioned and replaced without disrupting the Asset, by an alternate environmentally friendly system.
