[摘 要]海上平台部分建造较早,连续运行时间已经接近设计年限,甚至超出设计年限。现场部分仪控设备,虽能持续使用,但是仍存在安全隐患,部分设备存在老化腐蚀、功能下降等情况,仪控设计及火气探测设备布置与现行要求有一定差别。为了彻底解决现场问题,延长平台使用年限,结合现场实际情况,对海洋平台仪控方案进行研究。

Research on Instrument and Control Scheme for
Prolonging Service Life of Offshore Platform
Chen Xu-shen
[Abstract]Some offshore platforms were built earlier, and the continuous operation time has been close to or even beyond the design life. Although some on-site I & C equipment can be used continuously, there are still potential safety hazards. Some equipment have aging, corrosion and function degradation. There are some differences between the I & C design and the layout of fire and gas detection equipment and the current requirements. In order to completely solve the on-site problems and prolong the service life of the platform, the I & C scheme of the offshore platform is studied in combination with the actual situation of the site.

目前海上平台部分投产较早,属于老龄平台,已经接近甚至超出了设计使用年限。但是根据油藏预测,部分老龄平台在超期服役阶段仍具备较为可观的产量及经济性。为保证平台在超期服役阶段的安全与稳产,需要解决现有设备设施存在的各类隐患。例如平台原始设计与产能开发后的产量无法匹配,限制了生产产能的释放。由于设计过程中通常会留有较大的安全裕度,且使用期间也不断进行维修、改造和更换,因此相关设备和设施在设计寿命到期时仍然具有安全运行潜力。根据相关规范要求,针对已经达到设计年限的平台地面重点设备设施开展评估及方案研究,在了解平台动设备、静设备、仪控设备、电气设备、安全消防救生及辅助设施的现有情况下,对平台相关设备的延长使用年限提出可行性建议,使得在今后的维护、保养工作中,能更加高效地集中人力、物力和财力解决影响安全生产的突出问题,确保平台的安全运行。……
