WHY APPLY MECHANICAL PROTECTION ?
Assets, such as offshore pipelines, risers, spools or structures, may experience impact or abrasion after they have treated the external surfaces with an anti-corrosion coating. These impact loads or abrasions may occur during transport between the anti-corrosion coating site to the assets final location or during the installation phase (lifting equipment, assembly at spoolbases or on offshore vessel) or during pipeline operations (ploughing, trenching, fishing equipment, dropped objects etc). To reduce the risk of damage to the anti-corrosion coating, a second layer of material is applied to provide mechanical protection throughout the life of the asset. This protection can avoid the cost of intervention, a high cost in offshore projects in deepwater locations.
The cycle time to apply and cure the mechanical protection coating for assets (particularly field joints onboard S-Lay vessels) is critical. To achieve the fastest and reliable cycle times, training of the JURUNATURE / RAEapplication crew, formulation of material properties (particularly curing time and impact strength) and the design of fast and reliable equipment is essential.
FJ 3000- For CWC field joints requiring high density infill, JURUNATURE / RAE offers our FJ 3000 Infill Application (see products section). Aggregate is placed within the field joint annulus and the JURUNATURE / RAE formulated elastomer FJ 3000 is injected into the mold and fills the voids between the aggregate.
HDPF is produced in various densities for field joint infill on concrete coated pipe to meet the modern demands of the pipeline infill market. A patent is held for "Sea Sleeve", a dispensable polyethylene mold which is welded, using their "Intrafuse" system, around the field joint to form the annulus for filling. HDPF can also be applied using re-usable molds.
