Design Benefits

For naval architects, SPS offers scope for future ship designs to shake off many of the constraints associated with conventional stiffened steel construction. Huge lengths of welded steel stiffening are no longer required, saving literally kilometres of welding in a typical ocean-going vessel. The adjacent image highlights the simplicity of an SPS vessel versus the complexity of a conventionally designed bulk carrier hull.

The properties of SPS leads to simpler structures with the potential to carry more cargo. Build becomes more accurate with flatter and stiffer plates of precise dimensions more easily assembled in double-quick time. Tank and double hull spaces are easily inspected and long-lasting coatings more effectively applied.

The in-built properties of SPS – including fire protection, impact resistance and vibration damping – will contribute to safer ships in the future and reduce the risk of structural failure. SPS also adds value in sectors such as fast, lightweight craft and icebreaking tonnage.

For naval architects, SPS provides:
• Better corrosion and fatigue performance
• Greater strength but reduced weight
• Increased impact, blast and ballistics resistance
• Vibration damping and acoustic insulation
• Built-in fire protection
