To provide a speed-up nozzle for gas release, a gas release system of an offshore structure, the offshore structure and a gas release method of the offshore structure capable of preventing a gas from falling into a production facility area of the offshore structure on its release even if a released gas from an oil storage tank is heavier than the air, and of avoiding an adverse effect on production activities due to the released gas, for the offshore structures such as an FSO and an FPSO.SOLUTION: A speed-up nozzle 20 for gas release is configured to suck an outer surrounding air Air due to the suction effect of the injection of a released gas Gin entering from an inlet side and to release a gas into the atmosphere by making the outlet flow velocity of a mixed gas Gout faster than the inlet flow velocity of the released gas while diluting the released gas Gin with the surrounding air Air to make the mixed gas Gout by mixing the surrounding air with the released gas Gin.SELECTED DRAWING: Figure 1
【課題】FSOやFPSO等の洋上構造物において、貯油タンクからの空気より重い放出ガスであっても、その放出に際して洋上構造物の生産設備領域への放出ガスの降下を防止することができ、放出ガスによる生産活動への悪影響を回避できるガス放出用増速ノズル、洋上構造物のガス放出システム、洋上構造物、及び、洋上構造物のガス放出方法を提供する。【解決手段】入口側から入る放出ガスGinの噴射による吸引効果により外側の周囲の空気Airを吸引して、放出ガスGinに混合して混合ガスGoutにすることで、放出ガスGinを外周の空気Airで希釈しながら、混合ガスGoutの出口側流速を放出ガスの入口側流速よりも早くして大気中に放出するようにガス放出用増速ノズル20を構成する。【選択図】図1
