Fabric Formwork

[The illustration / sketches, below are only an indication of some of the solutions that can be manufactured]
 

Standard and Large Base Pipeline Supports

  • For pipeline crossings and freespan correction.
  • Different sizes for pipelines up to 84 inch.
  • Support height 0.20 m to 3.00 m.
  • Standard Supports for firm seabed conditions.
  • Large Base Supports for soft and very soft seabed conditions.
  • Stabilisation straps and scour protection skirt optional.
 

Jacking Supports

  • For crossing solutions to older pipelines with limited mechanical lifting possibilities.
  • ULO grout injected Jack-up supports raise the pipeline to then become a permanent support, so have a dual purpose.
  • For raising any solid structure on the seabed where other lifting solutions are not acceptable.

Mono Crossing Support

  • Supports installed over the lower pipeline at the crossing point for very acute angle crossings.
  • Mono crossing supports can be supplied with formed tunnel to avoid contact between the grouted structure and the existing pipeline.
  • Additional supports type Standard or Large Base installed at the correct span length between crossing point and touch down point of the pipeline.

Pillar Supports

  • Pipeline Supports for freespan heights exceeding 3.00 m.
  • Different ranges according to the diameter of the pipeline and soil bearing capacity and height requirement.

Prelay Crossing Support

  • ULO prelay grouted in-situ sleepers are a fast and simple way of providing support prior to pipelay.
  • The crossing can be prepared with a series of prelay supports of correct spacing and height or with a single prelay support only near the crossing point and additional postlay supports type Standard or Large Base according to the curvature of the crossing pipeline and the allowable freespan length.

Cable Crossing Supports

  • Standard Cable Crossing Support with formed tunnel for crossings with pre-determined crossing angle.
    Standard solution for 90° angle crossings.
  • Protection mattress placed and grouted over cable on support optional.

Dome Support

  • Cable / Umbilical / Flexible Pipeline Support.
  • Support with formed tunnel placed over the existing pipeline at the crossing point independent of the crossing angle.
  • Stabilisation / Protection mattress placed and grouted over the cable / umbilical / flexible pipeline on the support optional.

Wedge Cable / Umbilical / Flexible Pipeline Crossing Support

  • Cable / Umbilical / Flexible Pipeline Support.
  • Support with formed tunnel placed over the existing pipeline at the crossing point independent of the crossing angle.
  • Stabilisation / Protection mattress placed and grouted over the cable/ umbilical / flexible pipeline on the support optional.

J-Tube Support

  • Grout Bag to support the cable / umbilical or flexible pipeline from seabed up to the bell mouth.
  • Individual design for the specific situation.
  • Protection mattress optional, on support bag only or extending on seabed.  

Support with Neoprene Layer

  • Flat top support with Neoprene layer to allow lateral or longitudinal movement of the pipeline.

Shell Sleeve

  • 270° sleeve grouted on the pipeline for concrete weight coat repair or additional concrete weight coat.

Pipeline Stabilisation

  • Various solutions depending on water depth, current, pipeline diameter and stabilisation weight required.
  • In-situ grouted fabric formwork of individual design with exact adaptation to the pipeline diameter.
  • Similar type of grout bags used for pipeline protection.
