6”, 8” & 12” OD Duplex & 12” OD Carbon Pre-Fabricated Spools

9mm EPDM Thermal Heat Barrier & 94mm Glass Syntactic Polyurethane was specified by the Client to meet the Thermal Design Requirements of the Project.

Initially the steelwork to be coated was blasted to the specified cleanliness in this case SA2.5, and all quality checks performed.

9mm EPDM was applied in a build-up of layers, nylon tape wrapped and steam cured in a combination of our 2 on-site autoclaves.

The EPDM was then prepared for the moulding of 94mm GsPU, which was injection moulded in sections using project specific steel moulds and utilising our on-site GsPU pumps specifically designed for large volume castings.

The flange end terminations were then encased with 3mm Glass Reinforced Plastic to ensure that the insulation system is protected from any hydrolysis.

Mobilisation to the Quay Side for Spool Field Joint Coating involved mobilising our Site Team & Field Joint Coating Equipment and working alongside the Client to gain access to the joints for coating.

Joints were blasted and 9mm EPDM was built and cured via the use of heat tapes, with Solid PU injection moulded to encapsulate the GsPU chamfers and EPDM first layer, the Solid PU was overbuilt by 5mm onto the GsPU factory coating.

“Due to challenging delivery dates, the fabrication, testing and coating program for these spools was extremely tight. Through close collaboration and constant management dialogue, LJFCC pulled out all the stops to ensure client vessel mobilisations were not compromised, while still maintaining the highest level of quality coatings.”

14mm EPDM Thermal Heat Barrier & 72mm Glass Syntactic Polyurethane was calculated to meet the Thermal Design Requirements of the Project with 3mm Glass Reinforced Plastic at Flange End Terminations.

Initially the super duplex 25cr to be coated was blasted to the specified cleanliness in this case SA2.5, and all quality checks performed.

14mm EPDM was applied in a build-up of layers, nylon tape wrapped and steam cured in a combination of our 2 on-site autoclaves.

The EPDM was then prepared for the moulding of 72mm GsPU 1400, which was injection moulded in sections using project specific steel moulds and utilising our on-site GsPU pump specifically designed for large volume castings, leaving a 6mm EPDM thickness at flanges and cutback areas.

The flange end terminations were then encased with 3mm Glass Reinforced Plastic to ensure that the insulation system is protected from any hydrolysis.

Mobilisation to the Quay Side for Spool Field Joint Coating involved mobilising our Site Team & Field Joint Coating Equipment and working alongside the Client to gain access to the joints for coating.

Joints were blasted and 14mm EPDM was built and cured via the use of heat tapes, with Solid PU injection moulded to encapsulate the GsPU chamfers and EPDM first layer, the Solid PU was overbuilt by 5mm onto the GsPU factory coating, making a total Solid PU thickness of 77mm.

We would like to extend our thanks to LJF for their outstanding performance on a recent subsea piping project. The quality of their work was exceptional, showcasing their expertise and attention to detail. Their excellent communication throughout the project ensured smooth coordination and timely completion. We truly appreciate their dedication and professionalism and look forward to future collaborations.
