Fugro is a worldwide oil and gas service operator with the core business of data acquisition offshore, onshore and in the air. In a world with increasingly complex and costly systems being installed, often in remote, harsh or difficult to access environments, large scale continuous monitoring of these valuable and critical assets is becoming an increasingly important challenge. These monitoring systems need to collect wide variety of data: strain, sound, vibrations, pressure, temperature etc. FAZ Technology as part of the Fugro group has developed an ultra-high performance data acquisition system based on fiber optics, perfectly suited for acquiring large amounts of system and structural health and status data. We will present the concept, its performance and capabilities, and we’ll present real field applications. A core example will be a system installed on the Fugro offshore survey vessel Pioneer, which monitors a large suite of performance and health data of this vessel allowing online diagnostics as well as prediction of upcoming failure events. The system allows many sensors on a single light weight optical fiber, long distance recording and is robust and stable in a harsh offshore environment. Its functionality is well-suited for various offshore and onshore O&G industry installations, including subsea systems. We will discuss the functional details of the system, its performance, field data, and give an outlook on further developments.
