SPS – SANDWICH PLATE SYSTEM

SPS Technology’s Sandwich Plate System, or SPS ®, is a permanent, Class-approved structural composite comprised of two steel layers and an elastomer core. SPS is used for the permanent repair, strengthening and protection of vessels and assets.

 

Successfully used for 25 years, SPS offers simplified, more robust structures with little or no welding, less labour and less material. SPS utilises existing, corroded steel plating as the bottom face plate to form the sandwich composite. The resulting composite bond produces a stronger, flatter surface, with equal or greater than as-built strength. The reduction in fatigue and corrosion-prone details increases service life and reduces maintenance costs. SPS can be used for both large and small-scale repairs.

 

SPS applications can be undertaken while the vessel or asset is in service, eliminating hot work and dry dock visits.

 

Typical repair and reinstatement applications include:

  • Pontoon Reinstatement on semi-submersibles
  • Deck Reinstatement on all platforms or vessels
  • Tank top reinstatement
  • Side impact protection on FPSOs
  • Helideck, pipe deck & landing area strengthening
  • Sound and vibration deadening
  • Jack-up spud can reinforcement
  • Blast wall upgrades
  • Ice class upgrades
  • Port Infrastructure upgrades.

 

Typical new build applications include:

  • Control room blast protection
  • Anti-piracy citadel access protection
  • Dropped object protection.

 

The SPS COLD WORK solution combines onshore fabrication with offshore installation and eliminates hot work on board. This no-hot-work repair keeps assets in service and personnel safe while offering unrivalled sustainability compared to traditional crop and renew repairs.

 

Proprietary SPS is only delivered by trained SPS Technology partners.

SPS – the sustainable solution for Maritime and Offshore.

Structural composites such as SPS®, Sandwich Plate System, for structural reinstatements and reinforcements are forward-looking, progressive and genuinely reinforce environmental sustainability. Conventional 'crop & renew' creates a lot of waste: the corroded surface is completely removed and scrapped. Pipe runs and tanks beneath the corroded area may need to be removed or cleaned to commence a repair. Crop and renew is almost always undertaken in drydock or requires complex arrangements that add travel, expense and downtime costs. With SPS, the corroded surface can stay in place and be used to form one side of the structural composite repair.

TRADITIONAL CROP AND RENEW:

  • Requires up to 90% more labor
  • Is up to 11 more expensive than SPS
  • Projects are 3x slower compared with SPS
  • Might need dive boats and underwater cofferdams
  • Does not allow work in adjacent areas to continue in parallel
  • Lengthens project schedules if services need dismantling

ALL OF WHICH ADDS UP TO A LOT OF CARBON EMISSIONS.

For cost-effective maritime repairs and modifications, the clear choice is SPS.
