REEL INSTALLATION OF 15' CLAD STEEL PIPELINE WITH DIRECT ELECTRICAL HEATING AND IN-LINE T

摘要

The Nome Satellite project in the Norwegian Sea involved installation of a 9 km long 15" thermally insulated clad steel production pipeline. The pipeline is equipped with Direct Electrical Heating for hydrate control and an in-line T for connection of a mid-line reservoir.rnThe installation was performed in 2005 with the reel ship "CSO Apache" after completion of comprehensive qualification programs.rnThe Nome Satellite project represents a step forward in sub-sea pipeline technology, with the following main firsts:rn1. Reeling of clad steel pipelinern2. Direct Electrical Heating of clad steel pipelinern3. Direct Electrical Heating of pipeline with in-line Trn4. AUT of clad steel girth weldsrnThis paper presents experiences from the qualification and installation works.
