平台基有缆潜标实时内波监测系统

A cable subsurface buoy system for internal wave monitoring on the offshore oil platform

研究开发了一套依托于海洋平台进行安装的有缆潜标实时内波监测系统。该系统由温度传感器、温盐深传感器(CTD)、定点海流计(DVS)、终端接收机、绞车、钢缆、电缆及锚定重块等组成。温度传感器、CTD和DVS依一定的空间间隔串行连接并固定在系泊钢缆上。系统利用电缆实时供电、采用可寻址RS485总线进行控制和数据传输。集成的有缆潜标内波监测系统在中海油所属的PY30-1平台上进行了现场内波观测,成功捕获了多个内波过程,为获取长时间序列的内波实测数据、进而为开展南海内波机理和工程应用研究提供了有效的技术手段。

A cable subsurface buoy system based on the offshore oil platform to monitor internal waves was developed. The system was comprised of water temperature sensors, CTD, DVS, terminal unit, winch, steel mooring cable, cable and anchor, temperature sensors, CTD and DVS were attached to the steel cable with definite spatial patterns and spans. The system was powered through cable. Addressable RS485 bus was used for control and data transmission. The system was installed on a PY30-1 oil platform affiliated to CNOOC to monitor internal waves in situ, and captured many internal wave processes, which provided effective means to obtain long series of real-time internal waves for studing the machenism and engineering apllication of internal waves
