Offshore Platforms & Onshore Refineries

Off-shore drilling is a highly hazardous process with dangers from complex equipment and harsh environments all of which are present during the extraction process.

Toxic gas emissions are a danger in the environments in which offshore applications are found. They create unsafe conditions for personnel from a poisoning and explosive perspective. This results in various long-term health issues, injuries and fatalities. The ignition of flammable gases or vapours can lead to fire and even sudden, normally fatal explosions.

Hydrocarbons and hydrogen sulphide are a few of the well-known gases that exist within offshore applications.

Hydrocarbons are a group of gases made up of Hydrogen and Carbon atoms. All these gases are combustible and may be released under pressure from the well. Releases may also occur on the rig floor, top decks and living accommodation.

Hydrogen sulphide is a toxic gas that occurs naturally as a contaminant in sour wells and is one of the most regulated in offshore applications. Concentrations often exist at the lowest points of rigs, such as the cellar deck.

Safely monitoring the gases can be achieved by deploying a ‘Fixed’ gas detection system involving controllers and detectors often following a site survey by experienced gas detection professional like ATEXIS Solutions Ltd
