Riser, Pipeline and Flowline Blockage Remediation
Flexi-Coil® is a patented technology specifically designed for the efficient remediation of material deposition within pipeline, riser, and flowline systems. It is built to operate directly from the production facility topsides, often eliminating the need for vessel-based or subsea intervention.
Flexi-Coil is designed to recover up to 100% of pipeline blockage debris including waxes, sands, asphaltenes and hydrates using mechanical liquid jetting.
Applications
During deployment from the topsides, Flexi-Coil® is connected to a high pressure fluid pumping system which circulates through the coil and discharges via a multi-nozzle bottom hole assembly (BHA).
Due to its low-density composite materials, Flexi-Coil® is neutrally buoyant in seawater which assists in achieving deployment distances of over 10 kilometres from the insertion point, while navigating pipeline geometries involving over 1,000 cumulative degrees of bends.
Due to the design of Flexi-Coil®, direct vertical access or line of sight to the riser entry point is not required to deploy the technology giving greater flexibility for the system to be adapted to any facility and equipment to be positioned over multiple decks or even fully on a FPSO turret.
Benefits
By conducting remediation activities directly, this gives operators greater control over their operations and removes the need for any subsea intervention, leading to cost control and certainty in their approach.
Flexi-Coil is designed to recover up to 100% of pipeline blockage debris including waxes, sands, asphaltenes and hydrates.
With over a decade working with some of the worlds largest oil and gas companies, Paradigm’s Flexi-Coil has a proven track record in solving some of the most challenging pipeline blockage issues.
Previous case studies include the recovery of over 255 tons of wax from a single pipeline and multiple deepwater hydrates from restricted access FPSO’s.
FAQ
What problem does In-Riser Production Optimization solve?
It provides a low-cost way to stabilize and improve production from subsea wells as reservoir pressure declines and water cut increases. By installing in-riser gas lift or a velocity string, operators can mitigate severe slugging, reduce back-pressure, stabilize flow, and improve recovery—without the cost and complexity of subsea boosting or major facility modification.
What type of materials can Flexi-Coil® remove?
Flexi-Coil® has a track record spanning over a decade in removing a wide range of pipeline blockage materials including paraffin waxes, sands, asphaltenes and hydrates globally.
What distances can Flexi-Coil® reach?
Flexi-Coil® can reach distances over 6km / 20,000ft in standard pipeline systems, with added capability to reach in excess of 10km / 33,000ft in some cases.
How much debris can Flexi-Coil® remove?
Flexi-Coil® can recover up to 100% of pipeline blockage material, returning the pipeline back to base metal ready for inspection or restarting production as shown from previous projects.
What sizes of pipelines can Flexi-Coil® be used in?
Flexi-Coil® can be used in lines as small as 4” diameter with the largest project to date taking place inside a 24” export pipeline. Also as Flexi-Coil® is a composite material and neutrally buoyant, there is no risk of causing abrasive wear to the inner-wall or flexible carcass.
