... ABSTRACT The complexity due to the narrow space in a vessel or the complicated outfitting system of an offshore plant structure causes considerable ambiguities in the installation work. In this paper, an algorithm to determine the installation order for the geometric location of the piping...

... ABSTRACT The on-bottom stability of a submarine pipeline is a flow-pipe-soil coupling problem. For the integrated pipe-soil system under the action of steady current, two correlated instability modes could be involved, i.e., the lateral-instability of the pipeline and the tunnel-erosion...
