Abstract

The connection system allows to assemble two sections of a riser pipe used for offshore drilling, the riser pipe comprising a main tube and at least one auxiliary line arranged parallel to said tube. The connection system comprises a connector A for assembling two main tube sections and connecting means B1 for assembling two auxiliary line sections.Connecting means B1 are arranged, with respect to connector A, in such a way that the overall dimensions E of the connection system are smaller than the sum of the overall dimensions EA of the connector and of the overall dimensions EB1 of the connecting means.
