The ITC-PL Pipeline Renewal Process Explained

Pipeline segment to be rehabilitated with ITC-PL

The pipeline renewal process begins with the identification of ideal segments and access points for installation of ITC-PL, taking into consideration maximum segment pull lengths, the existing host pipe routing, sensitive environmental areas, urban conditions, classification changes, and other design aspects.

On-site manufacturing and pull-through of ITC-PL segment

For a given installation segment, the mobile on-site production unit is deployed on one end, a pull winch on the other end, and access points to the host pipe are locally excavated. ITC-PL is then produced and pulled through the host pipe during production, lining the entire host pipe segment with the product.

Completion of ITC-PL segment pull-through

The ITC-PL segment pull through is completed, and the segment is disconnected from the mobile on-site production unit and the pull winch. A time-delayed curing attenuation gel is added in the annulus between the host pipe and the ITC, providing mechanical isolation of the ITC from the host pipe and elimination of the annulus gas volume. 

Finalization of coupler and HRMS tie-ins

ITC-PL is then connected to adjacent segments through specially designed couplers. The integrated health and risk monitoring system is connected to a field deployed compute and communication system, and the access points are backfilled. The mobile on-site production unit is moved to the next installation segment and the process is repeated until the project is complete.

Fiber Optic Deployment Tool

The FDOT provides a method for the internal embedding of distributed fiber optic sensors in existing pipelines. The FODT enables deployment of BrainDrip's Health and Risk Monitoring System (HRMS) hardware and sensor systems, providing continuous health monitoring of the asset for encroachment, corrosion, temperature, flow, pressure, leaks, at high spatial resolution for event pinpointing. The deployment of BrainDrip's HRMS into existing pipelines using the fiber optic deployment tool provides the asset operator with the information and tools to gain operational confidence over the remaining life of the asset.

Full Scale Pipeline and Pressure Vessel Permeation Testing 

Braindrip has developed the first-of-its-kind pipeline and pressure vessel permeation test apparatus aimed at real-world characterization of full scale samples. The testing capability captures the effects of manufacturing such as thermoplastic fusion joints, non-uniform elements such as variations in reinforcement thickness, vessel geometry, bulk polymer properties, application pressure and temperature, and junctions of vessels with end couplings. The permeation test apparatus is rated for characterization of fuel gas applications including natural gas, gas blends, and has been specifically designed for hydrogen applications and its unique properties. The testing capability is ideally suited for providing accurate measurements of the loss of a gaseous product from a monetary and safety standpoint and determination of emissions rates for products that have regulatory requirements or expected environmental impacts.
