About the Cover
 
OUR COVER PICTURE shows a typical landfall using a coffer dam to pull-in the pipe from offshore, one of thetechniques being proposed by the designers of the Nord Stream pipeline project. The twin 48-in diameter, 1220-kmlong, pipelines will be the world’s longest subsea pipelines once fully operational in 2011. The first of a series ofthree papers describing aspects of the project is published on pages 167-173.
