Offshore umbilical cables often include both power cables and elements such as metallic tubes and signal cables. It was concluded from a recent failure of stainless tubes that AC corrosion was the failure cause. This paper describes how AC corrosion can lead to tube failure if a puncture exists in t...

In direct electrical heating system (DEHs), which is developed for subsea process to safeguard well stream through pipelines to topside process platform or shore, the production pipeline is also acts as an active conductor conducting large AC current to generate heat. The heating source is conductiv...

In Direct Electrical Heating (DEH) systems, the pipeline of subsea oil productions conducts a large AC current to generate heat. To further improve the effectiveness of the DEH, higher operating frequency is preferable. The electrical parameters of the carbon steel pipe are critical for a DEH system...

This paper presents results from AC corrosion tests on cathodically protected steel flowlines. An important factor, which has an increased focus in the industry, is to understand AC corrosion and how it can be mitigated. Tests have been carried out at 100 and 200 Hz, where no current transfer design...

A development program to further increase the competitiveness of the direct electrical heating technology has been initiated. By increasing the power frequency from 50/60 to 100-200 Hz, less current is needed to develop the same heat generation in the pipe. A test program is running with the purpose...

Cable-series impedance modeling is widely applied in electromagnetic transients simulations and power-loss calculations. The calculations are usually performed in a 2-D frame using the finite-element method or alternative approaches, such as MoM-SO, thereby losing the 3-D effects imposed by twisting...

Direct electrical heating is a qualified method for flow assurance in coated oil and gas flowlines. A concern is ac corrosion on connected templates caused by stray currents from the DEH system. This has prevented DEH from being installed on flowlines with in-line templates and restricted heating of...

Finite element computations are presented, studying the effect of cross-talk between cable elements of different lay lengths. 3D computations with twisted conductors and screens are compared to the more traditional 2D crosssection approaches. Current flow in screens and impedances of cables are obta...

FE computations are performed to investigate the current load on anodes and pipeline in the current transfer zone (CTZ) of a Direct Electrical Heated flowline. It is shown that there may be great differences in the current load on the anodes, and that there is a significant increase in the current d...

The operating experiences for more than 10 years of hydrate and wax management of pipelines by direct electrical heating have proved high reliability, robustness and operating simplicity. The system is in use for pipelines ranging up to 40 km length and water depths down to approx. 500 m. As the oil...
