Going safer

| onshore pipelines |

Worldwide energy demand is projected to increase more than 50% by the year 2030. Onshore pipelines are crucial in meeting this demand. The pipeline infrastructure is expected to grow at 7% per year through 2020, with 231,900 km of oil and gas pipelines already planned or under construction. Meanwhile, the world’s 3.5 million km of existing oil and gas transmission pipelines must continue to operate, often beyond their original design lives. To meet expectations, the industry must ensure safer operations, extended asset life and a reliable energy supply.

and lasting longer DNV works closely with operators and regulatory authorities to deliver comprehensive pipeline integrity strategies that manage risk and meet challenges in every phase of the pipeline life cycle. With our subsidiary, CC Technologies, we combine science and engineering to bring the best technology to the industry. Our innovative solutions help you maximise business performance, and keep pace with developments.

Operator’s Challenge In a competitive market with increasing regulatory and public attention toward safety, environmental issues and security of supply, being a best-in-class operator has become increasingly important. Yet pipeline operators also need to balance performance requirements, cost effective solutions and contractual obligations, while managing an aging asset.

ity review and Safety, Health and Environment (SHE) risk management. aSSESSING OPERABILITY DNV has developed the ‘Pipeline Systems Operability Review’ (PLOR), to assist operators in maximising pipeline performance. This tool evaluates technical and management systems, with respect to industry best practices and international technical standards. PLOR focuses on safety, environment and production availability, from design to decommissioning and goes beyond code compliance. It uses risk assessment to highlight issues that really matter and to identify appropriate mitigating measures. PLOR is unique in that it is built from the bottom up, beginning with detailed technical tasks and ending with management control systems.

We assist our customers at all stages of their Direct Assessment (DA) programme development and implementation, including:

Pipeline monitoring provides the data used to evaluate the susceptibility of a system to integrity threats from external and internal corrosion, third party damage, SCC and construction





The TransCanada Pipeline is a 14,500 km system that was installed in phases, beginning in the late 1950s. State-of-the-art coating systems were used to protect the pipeline at each stage of construction. However, aging and deterioration, along with a variance in soil types and coating protection methods required increased cathodic protection and different cathodic protection methods. This increased the cost of the corrosion remediation programme and created a risk of damage to newer, better quality coatings on parallel lines.

a new corrosion remediation programme. CCT/DNV provided an advanced in-line inspection programme, cathodic protection data and corrosion feature data. We also completed an economic analysis that prioritised piping sections.

CC Technologies, a DNV company, helped TransCanada evaluate the integrity of the system, prioritise areas for recoating and initiate

After laboratory evaluation and testing, the recoating programme was applied to more than 42 km of piping at a cost of $600,000 USD per mile, substantially less than the $1.1 million USD cost of replacement. The recoating programme also created a more cost-effective and reliable integrity management programme while preserving the assets of the TransCanada pipeline.
