Sandwich Plate System (SPS) is the name of a patented structural composite material comprising two metal plates bonded with an elastomer core. SPS was created in partnership with chemical manufacturer BASF incorporating Elastocore ® ^[1] as the core material. The SPS material is a direct replacement for stiffened steel and reinforced concrete in heavy engineering projects.

SPS is a licensed technology used globally in various engineered structures including maritime ships, offshore assets, buildings, stadiums and arenas, bridges and other special applications.

SPS was invented by Dr Stephen Kennedy following primary research in the field of ice-strengthened structures at Carleton University in Ottawa, Ontario, Canada and first patented in 1996. Intelligent Engineering UK Limited ^[2] was founded in April 1996 to commercialise the technology and later formally dissolved. The first recorded project involving SPS was carried out on the P&O Pride of Cherbourg, a Lloyd's Register approved vessel in 1999.
