Overview of Remote Monitoring for Corrosion Prevention
Caption Data are active in all types of Remote Asset Monitoring and have been involved in providing telemetry, with on line dashboards, alarming, reporting and monitoring to clients in the Corrosion Monitoring field since the company’s foundation in 2008.
With design lifetimes measured in multiples of decades, and failure costs in multi £ millions, the cost of permanent monitoring becomes relatively insignificant compared to the costs of reinstatement (to say nothing of litigation) in the event of an avoidable failure through corrosion. This is especially true if any such failure falls into the category of a “single point of failure” leading to total system/asset close down. Facilities Management providers often assume responsibilities for installations with potentially large liabilities in the event of later failures.
Whatever the Asset type, perhaps water or fuel pipelines & tanks, or reinforced concrete structures, knowing that the technology exists to manage associated corrosion risks in an automated, on line, real time way, makes reliance on periodic manual sampling techniques a dubious choice.
Key factors in this decision (to automate on line) will also need to reflect:
There are a number of considerations:
Local on-site corrosion monitoring
Caption Data offer a number of options to meet most needs. Probably the most popular for remote locations which are typical of Corrosion monitoring are units which connect to your instrumentation, and monitor locally at a high frequency. They compare results to configuration levels you set and amend remotely via the CDLSmartHub. Anytime a deviation occurs the unit will report in with an alert and the relevant data can be examined on line. If all is well the unit will report in at your pre-set reporting interval and upload data.
Where greater granularity such that transmission via GSM is impracticable, and or a failsafe is needed, then units with local SD cards storing data locally are available
Communications to the CDLSmartHub, can be via GSM, GPRS, Ethernet. For Corrosion Monitoring in remote locations GSM is usually preferred. Over the years Caption Data have developed considerable expertise at managing this process, with appropriate roaming and un-steered SIM cards, correct choice of Antennae, on board storage and intelligence and our software it is very rare, even in the most remote locations, that we cannot get the data to our servers.
Battery life is critical as corrosion monitoring often needs to be conducted in remote and or difficult to access locations. Our Nano Ultra hardware was especially designed for remote monitoring on Battery power and even with a SD card installed draws the lowest power and can work continuously for years in the field.
Of course the point of continuous remote corrosion monitoring is to enable you to take appropriate action in a timely manner. A key part of the Caption Data proposition is to take the data from the field, add to it with any other sources you have, and present it back to you in graphical format, aggregating data streams from multiple sites.
We will work with you or your clients to give the visualisation, trend analysis and data alarms/alerts to manage your or their corrosion risk. We generate Alarms and alerts and reports, all of which have a total audit trail so there is indisputable evidence about who received what when. All of this is provided with leading edge cyber security as standard.
