The use of flexible pipe in today's offshore installations and subsea projects is wide spread, the use of flexible pipe offers the operator greater choices for design and installation and in certain circumstances the re-use of the pipe for a differing project. Flexible pipe is by nature a complicated design with many varying material types and designs, with the complex and multiple types of line so a complex and varied monitoring and integrity situation arises.

As the use of flexibles increases inshore and in deep water projects so the need for developed and track proven reliability and integrity programmes exist. In industry terms flexible pipe is relatively new to the and the learning curve, research and development of the subject is ongoing. As the understanding of flexible pipe increases so does the identification of possible problems for the safe and continued operation of flexible pipe, as the manufacturers continue to improve on the design the industry sector is continually updating and revising the integrity and inspection programmes.

iicorr have an established and proven track record in flexible pipe issues, from the very first failure investigation to the development of a unique subsea online polymer coupon recovery system. iicorr were first involved in the failure investigation of a North Sea operators burst flexible riser, subsequently from this project came the development and installation of fixed instrumented monitoring systems which measured the performance of the polymer subsea and topside. All of this development and practical work has led to an in-depth knowledge base in iicorr.

The flexible pipe technology team of iicorr offer a wide magnitude of services and specific expertise in the field of flexible pipe inspection, monitoring and Risk Based Inspection. Our development team have been leaders in inspection deployment and inspection techniques of lines in situ as well as in the yard conditions. Recent programmes have seen the break through in Hydrogen Induced Cracking detection to name but one. The flexible pipe team are part of many external bodies which frequently discuss the topics and exchange information.

• Risk Based Inspection of individual lines, fields, operators entire assets
• Criticality Studies (lower end RBI to identify which particular line is most at risk due to operating conditions)
• Polymer coupon products, installation, and subsequent polymer analysis
• Instrumented polymer monitoring
• Polymer life prediction
• Annulus vent gas monitoring
• Design verification, material selection consultancy
• Internal visual inspection (in situ, refurbishment projects, failure investigation)
• Internal eddy-current inspection of the carcass, armour wire (internally or externally)
