Heating long, heavy oil pipelines
As an alternative solution to the skin effect system, Heat Trace Limited proposed that a series resistance LONGLINE heat trace cable would provide a less expensive system – both in the purchase of materials and components and, more importantly, significantly reducing the installation costs.Instead of welding carbon steel tubes to the pipe, a number of rectangular steel box sections would be strapped (not welded) over the anti-corrosion coated pipe during fabrication at the factory. Following this, a polyurethane foam thermal insulation and final outer cladding would be added.
When the fully assembled pipe stalks arrived at site, they were welded together as normal and the anticorrosion coating repaired as necessary. No further
welding operations were required.A total of nine rectangular box sections were used on the flow pipeline for this project, to accommodate 3 × 3 phase heating circuits. The box sections do not act as part of the actual heating system and are simply used as a method to get the series resistance heating cables onto the pipe, beneath the thermal insulation layer.The methods for pulling, or pushing, the cables through the box section can vary from project to project. This can be undertaken either by feeding pulling ropes
inside of the box section and pulling the cable through, or by pushing the cable through. This project allowed an installation rate of 20 m/min. of cable to push
the cable through the box section by hand, with 400 m lengths being successfully installed in a single operation.
On other projects, a capstan winch and pulling ropes have been utilised. This increases the installation rate to over 40 m/min. of cable.
Tackling Flow Assurance Problems in Multi‐kilometre Subsea Pipelines
As the search for oil and gas is extended, hydrocarbon products are being discovered in more difficult to access locations, sometimes at great distances from land and at significant depths in the oceans.
Industrial Heating Winter Checklist
Whilst cold temperatures are expected during the winter months, protecting your industrial facility has never been more important with the increase of costs and energy.
