[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.
