TUNNELLING MACHINE DEVELOPMENT FOR UNDERSEA PROJECTS - A REVIEW OF THE ISSUES

The decisions that lead up to the start of a major undersea tunnel will be the principal factors in determining the degree of success of the project. This paper covers issues from the viewpoint of a tunnel machine manufacturer and a contractor. The use of undersea tunnels are discussed, as are the types of machines that should be considered, as determined by the geologic conditions. Probe drilling, considered the most reliable method of detecting hazardous conditions ahead of the face, is reviewed. The state-of-the-art in pressure bulkhead shields is detailed. The contractor's viewpoint focuses on issues of risk sharing. The categories of risk and proper allocation of these risks are discussed, as well as the most effective methods of limiting and resolving disputes. The authors describe the contractor's expectations of the tunneling machine supplier, both before the construction contract is signed and after the selection of a machine. (A)
