About the Cover
 
OUR COVER PHOTO shows a recent 1.5-km long pull-in of a 24-in pipe-in-pipe district-heating pipeline in Rotterdam at a depth of 50m. A second horizontal directionally-drilled pipe will be installed before the end of March, 10m below the first. The contractor is Visser and Smit Hanab, on behalf of Rotterdam’s district-heating company Warmtebedrijf Rotterdam.
