Pipeline Integrity Management

Willbros is the industry partner with the most comprehensive integrity management capability for the maintenance and rehabilitation of oil and gas transmission, gathering and distribution pipelines as well as above ground hydrocarbon liquid storage tanks. 

United States oil and natural gas pipeline system provides an approximate 2.5 million mile underground labyrinth, transmitting hydrocarbons throughout the entire nation. Parts of the system are more than 50 years old and are in continual need of maintenance, repair and replacement.

To ensure the complete operational integrity of its pipelines, owners and operators need to rely on the expertise of companies who thoroughly understand pipeline safety issues and who have the competent personnel and technical capabilities to perform services to inspect, assess damage, mitigate, maintain, repair, renovate and replace pipelines wherever needed.

We offer the industry   Cradle to Grave capabilities with a proven track record at attractive rates.

Coupling our pipeline engineering ability with accumulated detailed GIS-based information, Willbros has the experienced field personnel and capabilities to undertake knowledgeable inspections and assessments of corrosion anomalies and MAOP deterioration. Through our 100+ years of pipeline construction experience, we have fully provisioned construction and maintenance crews available on a callout basis 24/7 to conduct the needed repairs, renovations and pipeline replacement in accordance with industry, NACE, API, ANSI and ASME codes and standards.

We have the independent capability to utilize and manage industry-proven integrity methods for internal and external assessments including In-Line Inspection (ILI), hydrostatic testing, and Direct Assessment methodologies. Similarly, we understand and work closely with qualified service providers of corrosion management techniques such as Close Interval Survey (CIS), Direct Current Voltage Gradient (DCVG), Alternating Current Voltage Gradient (ACVG). Our experience includes not just transmission pipelines, but similar expertise for full integrity management services on gathering and distribution pipelines and hydrocarbon bulk storage tanks.
