Bundle Clamps
A subsea production structure may be tied back to a fixed structure or an adjacent subsea facility by a set of subsea lines. Bundle clamps, including flat-pack bundle clamps for small bore service and injection lines, secured at regular intervals, provide an effective solution to laying subsea lines simultaneously. These lines also remain grouped on the seabed - a configuration which simplifies any subsequent burial operation.
Clamp bodies are moulded from an appropriate grade of polyurethane elastomer to a predetermined configuration of cylindrical recesses which bed the lines in place.
The securing systems include metallic bands or fasteners supplied in highly corrosion resistant materials.
