Abstract

The shroud is for elongated material such as cables, pipes etc typically used between a cable or pipe laying vessel and some form of submarine laying equipment. The shroud provides protection against damage generally and against tension variation and flexing due to manipulation and relative movement of the vessel and the cable etc. The cable etc. is passed through a stainless steel cylinder split in two halves (1a, 1b) along its length, hinged (2) at one side with interlocking sleeves (3a, 3b) along the other and positioned between the vessel and the bottom equipment. The inside surface is lined with a deformable rubber or elastomer material (6a, 6b), its volume being pressurised with air or nitrogen etc from gas bottles attached to the cylinder sides and/or from a compressor via a flexible line.
