Condition monitoring – subsea

A system with data loggers and sensors for connection to ROV or AUV was developed for the oil and gas offshore industry and for scientific projects. The logger collect and allocate the data of the sensors in real-time. Algorithm for identification of substances are implemented.

The data is transferred to the ROV controlling center respectively ROV pilot in real-time via the ROV tether. The optional OceanView™ DataServer arranges the data clearly and delivers alarm indication.

The ship data server is used to visualize and store online data. In addition, it provides diagnostic functions for SubCtech’s OceanPack™ water quality measuring systems or any other NMEA data transmitter. As a black box it can be configured as a simple passenger display.

The Top-Box™ is used e.g. in combination with the OceanPack™ Underway System to measure e.g. Air-CO2. The connection is carried out with a data line via the ship-LAN or radio. External probes such as meteorology or a GPS autonomous from the ship, can be installed additionally.

The OceanPack™ pCO2 mobile Analyzer was developed for precise measurements under difficult conditions. It is a small and handy measurement system with its inbuilt touchscreen for easy data presentation and the data logger. The Analyzer can be extended – similar to all our products – with further components like seawater pumps, plug valves, debubblers, sensors or a Top-Box™ to a be a complete measurement system. All our equipment such as the Top-Box™ is rugged and easy to maintain. It has been used successfully in extremely rough seas and in Arctic temperatures of up to -40°C.
