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.

INTRODUCTION For a range of applications, especially in oil and energy fields, there is a growing effort to construct ever more complex structures in areas that are increasingly more remote and difficult to access such as offshore and even deep subsea locations. Furthermore, the structures are operating in increasingly harsh conditions, pushing the limits of performance and efficiency. Such large scale assets, considering their operation and maintenance costs, are in clear need of continuous and remote monitoring, with minimal human interference, for a wide range of parameters, from pressure and temperature to strain and vibration, from a multitude of points distributed over long distances often in harsh and challenging conditions. Fiber optics, with its ability to transmit large rates of data with minimal loss over long distances, and its low production cost, provide an ideal platform as a backbone of a sensing network. Additionally, in many fields of operation, especially in the oil and energy applications, passive operation of fiber optic sensors where the sensing points do not require
