Autonomous subsea inspection is revolutionising the way we monitor and maintain subsea infrastructure. Cathx Ocean technology solutions combine precise data acquisition sensors with leading software analysis technology to enhance the efficiency, safety & preventative maintenance practices of pipelines and other subsea assets.
INTELLIGENT SOLUTIONS TO PROTECT YOUR SUBSEA ASSETS
OIL & GAS
Pipeline and Subsea Asset Maintenance and Safety
Cathx FDI solutions provide information on potential defects, corrosion, structural integrity or any other anomalies that may require attention. Cathx Ocean’s “Right First Time” principle ensures high resolution data quality is acquired first time. This delivers the correct raw data to provide critical information to maintain or repair pipelines and assets delivering significant cost savings and reduced HSE risk.

SOLUTIONS FOR TODAY
FDI® PIPELINE INSPECTION
Cathx Ocean has partnered with subsea pipeline operators, contractors and asset owners for many years now. We provide a range of technology solutions, tailored to meet the specific requirements of pipeline inspections. We deliver these through:
- Unique imaging quality
- High-resolution stills that enable unambiguous verification
- Precision laser data that supports detailed and accurate measurements.
- CLARITY Pipeline Module provides pipeline tracking and Freespan microservices
Pipeline surveys are traditionally carried out using video and multibeam at speeds of 0.5 knots or less. Data outputs are then reviewed manually. This is a slow and subjective practice but high-speed AUV and ROV systems create an attractive alternative. Cathx Ocean Fast Digital Inspection (FDI®) multi-camera systems offer reliable, high-quality images and colour point cloud data at speeds of up to 5 knots. Faster data acquisition can put pressure on existing processing tools.
Cathx Ocean’s laser-based, 3D shape detection provides real-time information about the position of the pipe in the Field-of-view (FOV). This can be used by the vehicle or its pilot to autocorrect the vehicle navigation ensuring the survey covers 100% of the pipeline as well as the adjacent seabed.
CLARITY’s Free Span Detection Microservice processes laser data in real time based on user parameters pipe diameter and minimum FreeSpan height accelerating survey times by a factor of 12* (from case study)
REAL TIME PIPELINE SURVEY INTELLIGENCE
But our aim is to do even more with this data. Working with integrity management groups, CLARITY Pipeline Module provides critical information earlier.
CLARITY
CLARITY is for anyone operating in the subsea survey industry who require data intelligence earlier, faster and more reliably. Earlier decision making is possible via on vehicle processing of sensor data.
Designed initially to find events in Cathx sensor data by processing shape and image data in real time, CLARITY has now been extended to enable machine vision and machine learning implementations to work with a range of other subsea sensors
AUTOMATED EVENTING
Cathx Ocean is leading the way for next-generation pipeline inspection solutions delivering cost reductions of up to 80% in some instances.
3D STRUCTURE INSPECTIONS
Close visual inspections of 3D structures were traditionally carried out using video. The associated slow speeds and stop-start vehicle operation made these very costly procedures.
But there are now proven alternatives. Cathx Ocean works with clients in this area, offering a number of solutions to overcome the limitations of conventional video inspections.
3D models, precision imaging data sets and laser point cloud measurements mean that data can be acquired at high speeds and quality checked on-vessel, while review and processing take place onshore. Likewise, by assisting simple navigation around 3D structures, our systems ensure high-resolution image quality.
Precision laser data is used to detect variances in structural dimension or differences in height or slump measurement. Comparing this data with previous results allows asset owners to identify changes at an early stage and take remedial action.
