    • A subsea riser integrity diagnosis system comprising: one or more fibres deployed along a riser, preferably along the whole length subject to any potential failure, or alternatively deployed over the interval most subject to failure, a fibre optic sensor interrogation apparatus optically coupled to the fibre(s) and operable to detect changes in temperature (DTS), vibration (CRN), or strain (FBG) sensed by the fibre optic strain sensor, and a central processor means adapted to receive multiple measurement data from the interrogation apparatus and operable to determine from the received data the current status of temperature, pressure, vibration, strain or other parameters along the riser and to determine if the status is within safe limits or whether any number of potentially damaging events has occurred and to inform the operator(s) for possible action to be taken to safeguard the integrity of the riser.
    • 一种海底提升机完整性诊断系统,包括:一个或多个沿着提升管布置的纤维,优选地沿着整个长度受到任何潜在故障的部署,或者替代地部署在大多数受到故障的间隔上的光纤传感器询问设备,光纤耦合到光纤 并且可操作以检测由光纤应变传感器检测的温度变化(DTS),振动(CRN)或应变(FBG);以及适于从询问装置接收多个测量数据的中央处理器装置, 从接收到的数据中确定沿着提升管的温度,压力,振动,应变或其他参数的当前状态,并确定状态是否在安全限制内,或者是否发生了任何数量的潜在的有害事件并通知操作者 采取可行措施来维护冒口的完整性。
