ABSTRACT:
A bulkhead for a marine seismic streamer section comprises a generally cylindrical body of rigid tough plastics material such as polycarbonate polymer, having an axial hole therethrough, through which passes the electric conductor bundle of the streamer section, and peripheral radial slots with hemicylindric bottoms receiving the tension lines of the streamer section. The bulkhead has an annular circumferential groove which is radially as deep as the axes of the bottoms of the slots and in which is disposed a belt of phosphor bronze, or stainless steel, or other strong corrosion resistant metal. The belt holds the tension lines in the slots and holds together the bulkhead, which is made of two sectors. One sector is greater than 180 degrees in extent and the other is less than 180 degrees in extent, e.g. the one sector may extend 240 degrees and the other 120 degrees. The split bulkhead is used as a replacement for one or more broken integral bulkheads in a streamer section, such section including a flexible outer tube with electrical and mechanical connection means at its ends, a plurality of mechanical tension lines extending inside the tube from one connector means to the other, a bundle of electrical conductors extending inside the tube from one end toward the other with electrical components connected to the bundle at intervals therealong, and bulkheads at intervals along the length of the streamer section. The bulkheads hold the outer tube in round and keep the tension lines and electric conductor bundle from tangling so that the streamer section can be wound on a reel.
