Flexible Riser Annulus Testing & On-site Annulus Gas Analysis

We design, manufacture and deploy offshore an innovative range of Riser Annulus Test Packs (RATP^TM) enabling to perform the following tests from one single portable unit:

• Annulus Gas Sampling
• Vent Port Flow Test
• Annulus Vacuum Test
• Annulus Free Volume Determination
• Positive Pressure Test

Our RATP^TM units are able to test two risers simultaneously and independently, making save significant time and costs for our clients. They turn annulus testing into a cost effective and reliable solution to determine flexible riser integrity. Our units are also extremely compact to be easily hand-carried on site.

In combination with our RATP^TM test packs, we deploy advanced portable gas analysers enabling us to measure in real-time the composition of annulus gas on-site. Gas analysers bring key added value to our riser test services by providing essential information on the root causes of anomalies detected with our RATP^TM test packs. They also promote more qualitative results than lab analysis as on-line/on-site analysis is done at the same P&T conditions as those of the annulus. They also make our client save significant time and costs by avoiding to keep samples under controlled P&T conditions and to ship them onshore for laboratory analysis.

Our RATP^TM test packs and portable gas analysers benefit from a solid reputation within the industry for their quality of construction, efficiency and robustness. They have allowed us to become a leading provider of flexible riser integrity services worldwide.

Beyond our riser testing and gas analysing capabilities, we make our clients benefit from a unique database of riser operating conditions, remedial actions and failure analyses built up over the years. This enables us to deliver unrivalled fitness-for-service analyses consolidated with our return of experience on various other fields worldwide.
