SPSTM is a patented structural composite comprising two metal plates bonded with a solid polyurethane elastomer core. The elastomer core provides support to the plates. It enhances buckling capacity and fatigue life of the structure.
Using the SPS® Cold Work solution to reinstate the deck of the FPSO Capixaba ensured:
Our well-trained SPS team proposed SPS Cold Work installation to deliver this permanent repair. We reinstated the existing deck and created a new composite section. A combination of bolts and structural adhesive was used to fit and join the steel components to form airtight cavities. The elastomer core was injected between the cavities. All steel components were prefabricated before being shipped on board for installation. This reduced the cost of the project. Welding requirements were eliminated. Time was reduced for the installation team, which in turn simplified project logistics. The design and process were evaluated and approved by ABS Brazil.
The SPS cold work solution reduced the amount of in-situ offshore work and POB requirements, allowing the FPSO to remain in operation. The fire-related risk was eliminated during the repair. SPS cold work was a great solution, as well as being class approved, for steel repairs where both hot work and POB are a constraint.Andrea Galter, Operability Lead Engineer, SBM Offshore
