The combination of Columbia Energy's engineering talent and environmental expertise for leak detection was coupled to produce excellence results at Hanford tank farms. The Columbia Energy leak detection system is evidence of our abilities to understand the objectives of a complex problem, maintain project focus, and accelerate the completion of a first-class product.

Single-Shell Tank Leak Detection System

Columbia Energy was awarded a fixed price contract from CH2M Hanford Group, Inc. in December 2003 to deploy an ASME NQA-1-compliant leak detection system for single-shell tanks at the Hanford Site. The effort was a first-of-a-kind deployment at Hanford that built upon performance test assessments conducted on the Hanford 105A Mock Tank. Columbia Energy's scope of work included design completion, procurement, fabrication, and field testing on an accelerated schedule.

• A first of a kind deployment, we played a critical role in design, procurement, fabrication, and field testing.

Our knowledge of the Hanford tank farms environment and expertise in permitting and nuclear safety helped to expedite the engineering and deployment of the leak detection system.

• The $2.5 million contract and initial deployment at tank 241-S-102 was accomplished in 4 months.

The project's success at tank 241-S-102 led to the client extending the deployment to another tank, 241-C-103. Future deployments at tanks 241-C-109, 241-S-109, and 241-C-102 are currently under discussion.
