Clarus Subsea Integrity Introduces the iCUE Digital Anomaly Detection App

New Technology Improves Asset Inspection Efficiency & Reduces Costs  

Clarus Subsea Integrity, an Acteon company that provides subsea integrity engineering services, today announced the introduction of the iCUE Digital Anomaly Detection App, pioneering new technology that provides rapid, accurate detection of anomalies by reviewing inspection video footage of subsea assets.  It is the latest addition to the company’s Digital Integrity Management Services portfolio.

Expertise in subsea integrity sets iCUE App apart

Drawing upon 14 years of experience in subsea integrity management services and its vast knowledge of subsea anomaly detection, monitoring and remediation, Clarus is uniquely positioned to provide this game-changing technology. Although there are apps on the market that purport to detect anomalies, the iCUE App is different. 

“What sets it apart is that the development was led by integrity engineers experienced in offshore inspections with in-depth knowledge of the actual assets and equipment that the app is trained to examine,” said Dharmik Vadel, Vice President of Clarus Subsea Integrity.  “Not only does the Clarus iCUE design team know how these systems operate and what they were designed to do, they have the domain expertise in equipment degradation mechanisms and defect trending, they know which defects pose the greatest risks.  Armed with this knowledge, the iCUE app draws upon a solid foundation of detection data that the others don’t.  It is truly in a class of its own.”

Anomalies detected at least 10 times faster than manual review

By using the App to assess footage of subsea risers, pipelines or moorings, for example, operators immediately receive a more accurate account of conditions that might otherwise go undetected.  In addition, the speed at which it analyzes footage and identifies anomalies is at least 10 times faster than manual review, which is significant when assessing whether an asset is fit for continued service or requires attention.

To achieve this, the App automatically carries out an engineering assessment of the inspection footage. The App is based on machine learning, and draws upon image analysis technologies. Clarus trained it with a machine-learning algorithm to accurately qualify an anomaly by using a structured data set of positive examples of anomalies.

Reducing unknowns improves asset risk profile

The capabilities of this technology are striking, offering meaningful longterm benefits.  Using the App to screen footage to identify and characterize anomalies reduces the number of unknowns. As a result, the risk profile of the asset is improved by making it possible to positively confirm its integrity or develop a plan to mitigate identified anomalies.

Integrity managers can also use it to trend anomalies from multiple inspections conducted on an individual asset field life.  This is useful when considering a possible extension for an asset that is approaching the end of its original design life. Armed with more accurate detection reports, they are fully apprised as to the extent, nature and severity of anomalies to determine whether they must be addressed immediately, require ongoing monitoring or remediation before qualifying the asset for life extension.

Lowering inspection costs, improving inspection quality

Conducting efficient, cost-effective inspections depends upon how swiftly they’re executed.  Because the App is designed to conduct anomaly detection screening following inspection data gathering, it’s a completely separate operation.  This means that inspections, whether conducted by remotely-operated vehicles or autonomous unmanned vehicles (ROVs and AUVs), focus solely upon capturing accurate video data of subsea equipment.  As a result, this phase is completed faster, reducing time and expense.  Given that inspection video is screened automatically, the App essentially lowers the time and expense typically required. 

“Cutting the cost of detecting anomalies in subsea assets is a vital element of Acteon’s strategy to reduce overall ownership costs by 30%,” said Paul Alcock, Executive Vice President of Acteon, parent company of Clarus Subsea Integrity.  “The introduction of the Clarus anomaly detection App is one of many planned key steps forward in helping our clients realize significant benefits, financially and operationally.”      

While operators have historically inspected subsea assets, engineering assessment of inspection videos is the exception, not the rule.  “This enhanced capability bodes well for integrity purposes,” said Vadel.  “The more useful tools we provide managers to help formulate an accurate understanding of asset conditions, the more effective their integrity programs and ability to maintain production.  The iCUE App is one of those tools that will play a critical role in making that a reality.”

Looking ahead

Acteon is firmly committed to developing a full-scale production level Anomaly Detection App.  This App will be capable of detecting anomalies in real time as video inspection data is gathered subsea. To this end, Clarus has already produced one Proof of Concept App for a common subsea anomaly type, and plans to finalize a second by Summer 2018.

Demonstrations available

Clarus is demonstrating the iCUE App, which automatically detects missing riser strakes and fairings while reviewing riser inspection footage.

Rising to the Challenge - Read the Clarus article in Oilfield Technology

John MacDonald, Clarus Subsea Integrity, Ricky Thethi, 2H Offshore, and Jonathan Deegan, Riskbytes, provide an economic and risk assessment of single and dual casing top tensioned risers.

The use of single or dual casing top tensioned risers (TTRs) is a key decision in the design of a dry tree system. The decision is risk based between the decreased cost of a single casing top tensioned riser and the additional barrier provided by dual casing risers. However, without any recorded incidents attributed to either riser system and very few incidents with TTRs in general, there is a general lack of industry data for direct use in a risk analysis. This paper presents a quantitative risk assessment methodology using historical data from blowouts combined with a typical planned riser configuration and assumed time on well. When combined with the cost between single and dual cased systems, the approach can be used to develop a basis of decision between the two riser configurations.

Life Extension or Decommissioning? Read the latest Clarus article in Offshore Engineer.

Understanding your asset is vital before making the big decision. Clarus Subsea’s Vinayak Patil and John MacDonald explain the key challenges of subsea integrity management in the Gulf of Mexico.

Operators in the Gulf of Mexico (GoM) must remain as proactive in the approach to subsea integrity as they have been in pioneering deepwater. Many of the early deepwater facilities are nearing the end of their design life, bringing to light the decision of what is next. However, making confident decisions in terms of life extension or decommissioning requires a thorough understanding of the asset history. For example, events such as high eddy current speeds are often not the priority during operations but may become a driver of life extension. Also while pushing designs for deepwater requires bespoke systems and flexible regulations, there are few prescriptive requirements to guide best practice. These leave operators and subsea integrity management (IM) contractors to determine the best practices for their asset IM.

Read the latest Clarus article in Offshore Magazine - Improved Risk Assessment Enhances IM

Clarus' Claire Zhao and Dharmik Vadel share their tips on how to maximize value from your IM risk assessment in this month's Offshore magazine.

A risk assessment is a tool commonly employed by operators during the stages of an asset’s life cycle, and can be used to varying degrees of depth and detail. Whether it is qualitative, quantitative, safety case or anomaly based, most operators use risk assessment techniques to identify critical components and prioritize inspection, maintenance and repair (IMR) work. 

To maximize the value of risk assessments there are a number of practical improvements that can help overcome challenges frequently faced during the application of risk assessment techniques. These allow the risk assessment process to be a multi-purpose tool to improve the overall performance of the integrity program.

Read the latest Clarus article in Offshore Engineer - Enhanced IM of Subsea Control Systems

Claire Zhao and Dharmik Vadel discuss condition monitoring as a proactive approach to minimizing downtime in this month's Offshore Engineer.

Control system failure is one of the top contributors toward unplanned shutdowns in offshore subsea production systems. Current practice includes a reactive approach to failure management including equipment replacement or a retrofit solution, which can be costly. Condition monitoring of control equipment using existing operational data can provide leading indicators of equipment degradation and potential failure. This approach enhances visibility of equipment health, estimates time to failure and increases production uptime via planned equipment replacement. Three key performance indicators are discussed below including hydraulic pump performance, subsea control valve utilization and digital communications efficiency to demonstrate the benefits of condition monitoring.
