ABSTRACT:
A gas venting apparatus for an offshore installation which vents excess gas produced from a liquid producing well. Said apparatus, including a flame extinguishing feature comprised of an elongated tube which depends from the flow tip of a gas venting conductor. To extinguish an accidentally ignited gas-fed flame, and to concurrently cool the flow tip, a weighted closure plate assembly is maintained in open position at the conductor flow tip. A high velocity stream of water directed against the closure assembly urges a closure plate into sealing engagement with the gas conductor, thereby choking off the flame, and terminating the gas flow.
