Barr has provided engineering services for the cathodic protection of pipelines for multiple clients and projects. Cathodic protection is used to extend the life of pipelines and other buried facilities by providing a means to reduce and prevent external corrosion using an impressed current system or a sacrificial anode system. Barr provides services for evaluating, designing, and installing these systems and other related monitoring systems.
Barr’s cathodic protection projects include developing field test plans, reviewing and analyzing data and system performance, conducting desktop studies of subsurface conditions, designing new cathodic protection systems or repairs to existing systems, and designing monitoring and testing systems (coupons, remote monitoring, and test stations). We have Association of Materials Protection and Performance (formerly NACE International) certified cathodic protection personnel and professional engineers to oversee the designs and analysis of field data.
Some specific project examples include providing engineering services for an impressed current cathodic protection system design (including conventional, distributed, deep well, and linear anode groundbed systems) for hydrocarbon pipelines in multiple states across the Midwest. This includes projects covering mainline portions of the pipeline and within pipeline pump stations and other facilities. Barr has also provided galvanic anode cathodic protection system design for pipeline casings and stormwater pipes at critical levee crossings for a flood control project in North Dakota. In addition, we have provided cathodic protection design for a chemical pipeline at a highway crossing between facilities in Minnesota.
By providing cathodic protection design, Barr has helped several confidential clients reduce maintenance costs and extend the life of their pipelines and other underground facilities.
