摘要:浮式生产储油轮(FPSO)为现今海洋石油开发的主流设施之一,其生产运营期通过单点实现与其他生产设施的连接与FPSO的定位,为了保证在FPSO设转率径内有施工需求时,不影响正常的生产运营,需要对FPSO进行限位作业,本文以激海明球号”FPSO在BZ25-1油因的限位作业为例,分新作业海域环境条件,计算FPSO所受到的风、流等环境载荷,确定限位方案、拖轮及其相关属具的配置,对保证 FPSO海上作业安全性有着重要的意义。

Abstract:NowadaysFPSO isonetypeofthemainstream ofshore oildevelopmentfacilities.During its production, itcanconnecf with other productionfacilities andfix the FPSO position via a single point. In orderto guarantee that there is no impacton the normal production when there are o of "Bo Hai Ming Zhu" FPSO as an example, which locates in BZ25-/ oifield. It determines the position limiting scheme, and the tug and relevan fitings required by analyzing environmental conditions of thesea area and calculating the emvironmental loads such as wind,fow and so on.It is of great signijficance to ensure the sqfety of FPSO operation on the sea
Key words: FPSO: position limiting operations; load analysis; fug configuration

完成的一小时后,将其放入热处理炉中保温后随炉冷却。最后对优化后的铸造工业进行试验,最后得到:在实际铸造中无缩孔、缩松和气孔出现,实际使用中运行状态良好,同时也验证了铸造数值模拟结果的正确性。

图5铸造后的叶轮
图5试制图从图中可以看出,用上节所选择的工艺精铸出的蒙乃尔叶轮外观良好,没有可见的缩孔缩松和气孔,在盖板上也没有裂纹或者冷隔产生。在实际使用中,该叶轮运
行状况良好。结论
通过对蒙乃尔合金的叶轮铸造工艺进行数值模拟可以得在充型和凝固过程中,浇注温度的变化对其影响不大,
到:
缩孔缩松的产生虽然随着浇注温度的提高,范围越来越大;由于蒙乃尔合金的易吸气,要采用低温快浇的办法进行浇注,1400℃的浇注温度为最佳的浇注温度:在竖浇道和叶轮盖板交界的区域和叶片出口的区域,有效应力值较大,需要对该部位进行处理;边界处尽量不要出现尖角,且在浇注
