ENVIRONMENT REPORT 2018

Gas Venting Venting is also subject to consent under the Petroleum Act 1998 through application to the OGA. All applications undergo a detailed review and all venting activity must be reported in EEMS. Just under 62,000 tonnes of gas were vented on the UKCS last year, a 40 per cent increase on 2016. Nearly one-thirdof the2017 total was due toa single installationwhichhas beenunable to flaredue to incombustible gas emissions, where the carbon dioxide content was too high to enable ignition. Gas venting is reported under EEMS as either operational, maintenance, emergency or gross. Gross is reported when a breakdown is not available and could therefore be any of the other categories; the majority falls into this category, as shown in Figure 14.
