Sandwich Plate System


SPS deck overlay system – SPS is a composite structural laminate that replaces conventional stiffened metal plates. SPS uses a solid polyurethane elastomer core encased by metal faceplates. It is used in both newbuilding and repairs (SPS Overlay).

The SPS overlay technique was used on the ro-ro vessel EUROPAN NAVIGATOR which required the repair of its upper vehicle deck. Completed in only 20 days, UK-based Intelligent Engineering in unison with Cammell Laird laid down a total of 884m2. The standard procedure was a single day of shot blasting, followed by five days of steel work preparation which continued alongside 14 days of elastomer injection.
