Sandwich plate system
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 ® as the core material. The SPS material is a direct replacement for stiffened steel and reinforced concrete in heavy engineering projects. SPS is licensed for use by the SPS Technology group of companies and is used globally in various engineered structures including maritime ships, offshore assets, buildings, stadiums and arenas, bridges and other special applications. History. 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 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. SPS Technology UK Ltd. was formed on 4 August 2017 and is the headquarters of a group of companies: SPS Technology Asia Pte Ltd; SPS Technology North America Ltd. (Ontario, Canada and Louisville KY US) that license and  provide technical support for projects using SPS through a network of international agents. Notable Projects.
