Wires&Bytes BendSense cable for vectorial detection of bending in three dimensions

13 Apr 2021

A deformation applied to an optical cable results in positive or negative longitudinal strain exerted along the circumference of the cable and this can be exploited for bend measurements using fiber optic cables. It is well-known in the industry that optical fibers are sensitive to longitudinal strain. A one-dimensional displacement — either expansion, or compression of the fiber — represents scalar strain, whereas three-dimensional displacement represents vectorial strain. The latter provides information on “bending” at that position. This is where a special class of fiber optic bend measurement cables can be deployed. The intelligent cable design using off-the-axis integration of multiple fibers inside the cable will provide full information on bending at that location.

Example of prototype evaluation in the lab

 

Vector displacement information is extremely useful in various applications such as crack growth monitoring, umbilical, pipeline, tunnels, powerlines, and robotic arms. When a cable is embedded into the structure, it will take the shape of the structure allowing to explore the configuration. One of the demanding needs of the industry is to understand the dynamic movement of the structure using fiber optic sensing. Hence a cable that provides information on the cable bending along the entire length brings several benefits to the owners and operators, e.g., providing dynamic inclination information for the long structures and infrastructural objects helps the owners to predict the lifetime of their assets.

Example of bend measurement cable type

 

For fiber optic cables the cable bend measurement capability can be categorized in measurement ranges:

  • short range: of a few meters
  • middle range: of a few tens and a few hundreds of meters
  • long range: of a few kilometers or tens of kilometers.

Measurement ranges determine possible interrogation techniques to be used. Long-range bend measurements capability has always been the focus for Wires&Bytes. The integration of these interesting features into new generation of fiber optic cables has resulted into a family of cables called MulitSense. Various MultiSense designs have been implemented in the field and their technical capabilities have been exceeding the customers’ requirements and expectations so far.

Taking into account the demanding applications, Wires&Bytes has developed a BendSense cable. Our new cable design is a further evolution of our MultiSense design to provide information on vectorial deformation from the cable. The new cable has multiple fibers, configured either twisted or non-coplanar inside the cable. This allows optical fibers to be sensitive to the bending regardless the bend plane and offering the end user to deduce bend direction and amplitude of the deformation.

Possible encapsulation options for bend measurement cables

 

All the cables have been thoroughly tested in our lab using BOTDR technology making sure Wires&Bytes delivers fit-to-purpose products. Wires&Bytes aims at helping you to develop and manufacture cables for specific bend measurements. You can be rest assured you are provided with the best technique to interrogate your cable, data acquisition, processing, and visualization, so you can get detailed insights of your assets’ integrity with our bend measurement cables.

  • Four: Improper or neglected maintenance
  • Five: Fire

The history of bridge construction and catastrophic failures has taught us a lot of things, but especially to think about safety first. Lessons learned: all the problems listed above can be tracked! Early detection of damage leads to prevention of critical issues and structural faults, reducing repair time and costs, and most importantly saving peoples’ lives!

Wires&Bytes offers a range of cables for structural health monitoring: Non-metallic MultiSense, UniTEF, SensoWire, and others. Discover more on our website.

Non-metallic MultiSense. Application (real photos!)

11 Feb 2021

Last week we unveiled a Non-metallic MultiSense cable, today let’s take a closer look at its applications.

MultiSense is not just an eye-catching name, it provides a platform to monitor different physical changes with a single cable. Non-metallic version is fully dielectric (it cannot be revealed by metal detectors!), making it safe to use where electric current can be an issue. If you need a more robust cable with higher tensile strength, it can be encapsulated in stainless steel.

 

  This cable can be produced in two options:

  • as a finished product ready for deployment
  • as a semi-finished product for further integration into larger cable designs and other structures

  Where Non-metallic MultiSense can be applied:

  • all types of Distributed Fiber Optic Sensing systems (DFOS): DTS (temperature), DAS (acoustic), DSS (strain)
  • applications that require enhanced acoustic response using standard telecom fibers
  • distributed monitoring: tunnels, roads, railways, conveyor lines, pipelines, dams and dykes, overhead and overground electric power lines, underground high-voltage electric lines
  • intrusion detection
  • simultaneous multiple measurements along with fibers for data communication

What is the difference between traditional, digital and fiber optic slicklines?

20 Jan 2021

Today’s oil and gas industry challenges require companies to deploy the most up-to-date technologies or upgrade the current ones as an alternative to the traditional mechanical wireline services.

Standard slickline servicing for the oil and gas industry can provide an effective well maintenance by deploying and manipulating the downhole tools. For many decades, slicklines and wirelines are used in well interventions that provide data with limited accuracy and acquisition frequency. The results depend very much on the skills of the operator and the quality of used tools. With the introduction of new disruptive technologies, these limitations have now overcome, for example, with the introduction of fiber optic (FO) slickline — the slickline/wireline becomes a distributed sensor along the whole length hence turning the full length of the slickline into a dense chain of passive segments, each one transformed into measurement gauge sensitive to external perturbation and physical quantities, detecting and measuring temperature, sound/acoustic, strain and pressure.

Wires&Bytes, which is at the forefront of the technology, have looked ahead and developed and offer FO slicklines and FO wirelines based on advanced fiber optic distributed sensing technology, DFOS. Wires&Bytes slickline tracks and monitors well activities delivering cost-effective data from the downhole allowing to make the quickest desicions for operators and owners, in many cases at wellsite.

 

The timely availability of well health information is critical to the oil and gas companies, where decisions hinge on the availability of useful data to implement it quickly and efficiently. The DFOS based slickline and wireline is an efficient and reliable tool, saving time and operating cost to the well operator, providing real-time information from the wells through an intelligent monitoring and allowing to identify and rectify issues and flaws in a timely manner.

Are you ready for advanced fiber optic sensing for precise well data at the speed of light? Let us know all your requirements and we will provide you with the monitoring solutions which are reliable, cost-effective and would increase your Return-on-Investment (ROI).
