INTRODUCTION

Offshore inspection services for pipelines and risers are growing as the worldwide infrastructure of pipelines and platforms ages. Moreover, regulations today require periodic inspections for corrosion in splash zone of risers, caissons, conductors, spoil pieces and sub-sea pipelines because coatings degrade. It is highly recommended that these areas be inspected to detect corrosion before failure and create maintenance or replacement plans. Traditional visual and UT wall thickness techniques are often not practical due to restricted access and protective coating. Advanced NDT methods for inspections are required to limit human intervention in high-risk areas and obtain better inspection data for more accurate risk-based inspection (RBI) monitor programs and life extension for offshore platforms.

THE Applus+ SOLUTION
Managing and safeguarding the integrity of client assets has been a prime concern for all operators of refineries, chemical plants and power plants for decades.
 
For over 75 years, Applus+ has been a trusted partner in providing customers with clear on-site data via its high-tech NDT offshore services. Working closely with our clients gives us a full understanding of their requirements, allowing Applus+ to tailor the NDT offshore inspection solution to the specific task.

Applus+, with its own Technology Centre and Engineering Department, can custom build specialised robotics for offshore inspection projects, adding value to our offshore inspections whilst helping the client to reduce costs.

For riser inspections, we offer numerous specialist products, including: internal visual inspection tools; offshore drone for external HD visual inspection; long-range ultrasonic; pulsed eddy current; tethered, intelligent pigging-inspection solutions; automated corrosion mapping; automated TOFD systems; sub-sea ACFM; and riser cleaning and inspection tools.

Applus+ has numerous patents dating back to 1940 - a testament to our commitment to research and development in the field of non-destructive testing.
TARGET CUSTOMERS
Statistical data collected over the last 30 years indicate corrosion as the main cause of failure in risers.

Existing offshore assets are nearing the end of their serviceable life. Companies wanting to extend the life of their assets are deploying comprehensive offshore inspection and maintenance programmes.

Statutory regulations also require assets to be inspected on a more regular basis to meet the rigorous safety and environmental requirements and enable an offshore asset to operate safely throughout its extended life-cycle.
