Recently, BJ Process and Pipeline Services completed a pipeline degassing operation in a remote and environmentally sensitive area of Ireland. The asset operator needed to clear a 9.5-mile (15.3-km) section of an 18-inch diameter natural gas pipeline and render it safe to tie-in a new section. In the past, crews would have depressurized the line to as low a pressure as possible before "cold venting" the residual gas to the atmosphere. However, new quality, health, safety and environmental (QHSE) policies deem the practice of cold venting as detrimental to the environment and potentially hazardous. To ensure that the pipeline operation complied with local environmental protection legislation, BJ PPS provided "clean burn" flaring services that proved to be a successful alternative.
