Tyco Thermal Controls, Menlo Park, Calif., will be providing Cairn Energy of India with a skin effect heat-tracing system (STS) for a new underground crude oil pipeline. Once completed, the system will be the longest of its kind in the world, according to the company. With a value of nearly $14 million, this also marks the single largest product order ever received by the heat tracing systems maker.

Cairn Energy has commissioned Tyco to design, supply and provide field-quality assurance for the project, which is scheduled for completion in October. Tyco Thermal Controls provided nearly 400 miles of STS for the Barmer Salaya pipeline, which is a critical line used for transporting crude oil from the CEIL oil field in Rajasthan to a refinery in Salaya, Gujarat.

The skin effect heat tracing system will provide thermal insulation and electrical heating along the length of the pipeline to reduce the viscosity of the oil inside. The pipeline must be maintained at 149°F (65°C).

The design and engineering activities for the pipeline are being handled at Tyco Thermal Controls' STS Knowledge Center in India, with review and approval by the STS Knowledge Center in Houston.
