Rostock tunnel project: innovative approach In the German harbor of Rostock, Boskalis subsidiary Heinrich Hirdes is involved in the building of a tunnel under the river Warnow. The remarkably low weight of the tunnel elements demands an integrated approach to the work. No separate links, but a connected chain of work. “The nice thing about the Rostock tunnel is that we are involved in the project from A to Z, and not just in a part of it”, says Paul van der Burg, a specialist in submerged tunnels & special survey applications. Heinrich Hirdes did all the dredging work using its own equipment and people. A joint venture was established with the German subsidiary of Van Hattum en Blankevoort for the immersion of the six tunnel elements. “A real ‘home market project’”, says Heinrich Hirdes director Jan de Reus. “Because the concrete tunnel elements are relatively light, there was a risk that they might float upwards during and after immersion. To make sure that didn’t happen, ballast tanks in the elements were filled up to the top with water. In addition, the immersion of the tunnel elements and all the ground and dredging work involved was dealt with as a single integrated process. That needed well-planned logistics and considerable precision in the implementation of the work,” continues Jan de Reus. The design of the armor on the roof of the tunnel also required precise calculations for another reason, namely the fact that the depth of the fairway had to be maintained. So Heinrich Hirdes talked to the number crunchers at Boskalis’ engineering consultancy Hydronamic. In the spring of 2003, the layer of stones that they have worked out as anchor protection will be positioned on top of the tunnel. 70 Annual Report 2002
