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...

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...

This paper considers measurements of electrical parameters for subsea power umbilicals. Electrical system parameters given in the umbilical datasheets may be inadequate for dimensioning the electrical system as they often are IEC-specifications. The parameters may be estimated by finite element anal...

As it becomes profitable to extract oil and gas from smaller reservoirs, jumpers (t-offs) connected to the main flowlines become necessary. Hydrate management of these jumpers may be solved by electrical heating systems. This requires development of new subsea electric power components. The most vit...
