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.
For repair and structural strengthening applications, the existing corroded or worn existing corroded or worn plating as one side of the composite panel to which perimeter bars and top plate are fixed to form a cavity into which the elastomer core is injected. The resulting composite fully restores or enhances the strength of the original structure.
SPS is a permanent structural repair solution that is approved by all major classification societies. SPS has completed 5500+ maritime and offshore projects for a wide range of applications. Examples include tank tops, bulkheads, decks
, and ramp strengthening.
1) It is durable
An SPS repair is designed to last for the lifetime of a vessel or structure which has been proven with over 20 years’ experience in the market and thousands of hours of testing.
SPS fully restores and strengthens to build strength with greatly improved impact resistance and fatigued life.
2) It uses lesser steel and lower cos
The top plate required ranges from 4-8mm. Depending on the repair design the elastomer core thickness is between 20mm50mm. With continuous elastomer core support, SPS panels remain flat with no local buckling.
Reduced steel requirements mean that SPS reduces the cost of repair in comparison with conventional crop and renewal.
3) It is faster
SPS is a non-disruptive repair, completed in a fraction of the time crop and renewal as SPS uses the existing worn-steelwork to form one side of the composite panel formed by a new top plate and elastomer core.
“Using SPS rather than conventional crop and replace methods reduced our repair schedule by 40%.”
