SPS FOR

MARITIME

The world’s leading class-approved structural repair solution

When it comes to strength, quality and permanence for vessel and asset repairs in the maritime industry, nothing compares to SPS.

For over 25 years, SPS Technology has provided build and repair solutions to vessels and offshore assets on a global scale.

Trusted by engineers, owners, and surveyors, SPS is a structural composite designed to protect the safety of POB, eliminate the need for dry-docking and permit the use of innovative cold work repair methods— all while saving you time and money.

SPS Tank Top Reinstatement on Allseas’ Solitaire.

Allseas’ Solitaire is one of the largest pipelay vessels in the world and has completed some of the most challenging projects in which heavy pipe has been laid in very deep waters. Fatigue and corrosion meant 550m2 of tank top in hold No. 6 needed to be reinstated. After a detailed assessment of the necessary vessel repair was carried out, Allseas opted for SPS Technology’s Sandwich Plate System instead of conventional steel renewal.

Build a better tomorrow with SPS – the sustainable solution to vessel and asset repair.

Instead of conventional ‘crop & renew’, using structural composites such as Sandwich Plate System, SPS®, for structural reinstatements and reinforcements is forward-looking, progressive, and genuinely reinforces environmental sustainability.

Compared to Crop and Renew, SPS offers:

  • 55% less carbon dioxide equivalent
  • 70% less welding (100% for Cold Work)
  • 60% less new steel
  • 90% less O2 and acetylene cutting (100% for Cold Work)
  • 75% shorter schedules

The SPS Cold Work solution reduced the amount of in-situ offshore work and POB requirements, allowing the FPSO to remain in operation. Fire-related risk was eliminated during the repair. SPS Cold Work was a great solution, as well as being Class Approved, for steel repairs where both hot work and POB are a constraint.

SPS was the only way to keep the linkspan bridge open and achieve a first-class permanent repair. [SPS Technology]’s capability and commitment to ‘sweating the detail’ of the planning was exemplary.

I have been very impressed with the work carried out by SPS.

Paul ThomasSenior Chief Engineer, Stena Europe

After sixteen years of being involved with SPS, I feel I can confidently state that the product, when applied properly, can outperform conventional repairs in both cost and life span. We consult for a client who regularly inspects a bottom shell cold work SPS repair solution fitted in 2005 to repair a significant hull breach. The repair continues to show no signs of deterioration and is still performing as well as it did the day it was fitted 16 years ago.

Applications

Corrosion Repair

Corrosion Repair for Maritime with SPS Technology.

Repairing and strengthening existing steel structures to meet ‘as built’ strength with a permanent, class-approved repair solution including:

  • Tank Top Corrosion
  • Grooving Corrosion
  • Deck Upgrade
  • Operational Route and Port Infrastructure Repairs

Operational Route / Port Infrastructure Repairs

Operational Route and Port Infrastructure ship repairs with SPS Technology.

SPS structural composite panels offer fast and economical ship repair close to operational routes, including passenger and vehicle decks and larger port infrastructure projects like link-span bridges. Adjacent and underdeck services are not disturbed, reducing project risks. Careful project planning and execution ensure that vessel dockings and sailing schedules are unaffected. 

Please watch our YouTube video for more information about using SPS in link-span bridges.

Strengthening

Strengthening for Maritime Assets with SPS Technology.

Strengthening existing steel structures through permanent, class-approved structural ship repair, including:

  • Deck Loading Upgrades
  • Dropped Object Protection
  • Ice Class Upgrades

Deck Loading Upgrades

Deck Loading Upgrades for Maritime with SPS Technology.

SPS has been extensively used to increase the loading capacity of existing decks. Costly and inefficient conventional ways include replating with thicker steel and additional stiffeners. SPS utilises existing structure to strengthen decks for higher loading capabilities.

Ice Class Upgrade

Maritime Ice Class Upgrades with SPS Technology.

Through the application of SPS to the ice belt region, vessels can be upgraded to ice class rating. It is a simple, cost-effective method that improves the lifetime performance of a vessel.

Tank Top Reinstatement

Maritime Tank Top Reinstatement with SPS Technology.

SPS delivers an improved, impact-resistant and permanently flat surface.  Dishing is eliminated leading to easier, more efficient cargo handling, reduced turnaround times and improved long-term operational economics. Maintenance costs are reduced as a result of enhanced resistance to wear and corrosion.

Thermal Insulation

Thermal Insulation for Maritime with SPS Technology.

Structural composite SPS can be used to create thermal boundaries enabling operators to, for instance, maintain different but very stable temperatures in individual tanks and optimise tank storage. 

Alternative solutions such as conventional steel cofferdams involve constructing void spaces in adjacent tanks. These are not structurally efficient and may create additional maintenance costs and operational risks from the possible build-up of explosive gases.

Fire Protection

Fire Protection for Maritime with SPS Technology.

SPS is exceptionally resistant to fire and an extremely effective barrier to heat, flames, smoke and toxic gases. It will help to contain a fire and prevent it from spreading to adjacent compartments, greatly limiting the growth of a fire through a structure. A 25mm [1in] SPS core provides an A60 barrier. SPS also has H120, H60 and J60 certification.

Chemical Resistance

Chemical Resistance for Maritime with SPS Technology.

Tests have demonstrated SPS’s elastomer core is impermeable to hydrocarbons, cannot absorb any chemical without volume change, and will not degrade, react with, nor contaminate the chemical.

The SPS solution can employ bi-metal perimeter bars to allow easy welding of carbon steel to the existing structure and stainless steel plates to the stainless side of the bi-metal bars. In addition, the thermal conductivity of SPS is sufficiently low that the elastomer core adequately provides the required level of insulation.

SPS also protects the main structure from cryogenic spills or vulnerable areas of LNG carrier decks and loading platforms.

Please read this case study about protecting tanks with SPS.

Citadel Protection

Citadel Protection for Maritime with SPS Technology.

SPS is an ideal product for citadel hardening. The composite structure of SPS provides impact protection that is far superior to standard steel water-tight doors and can be retrofitted into existing doorways more readily than other alternatives.

Tested by major defence institutes, SPS is proven to absorb more blast energy through membrane action than equivalent all-steel structures, resisting rupture and maintaining structural integrity. SPS is also highly resistant to projectiles delivered at shorter strike ranges and higher angles of attack.

Noise & Vibration Damping

Noise & Vibration Damping for Maritime with SPS Technology.

Through the application of SPS to affected areas, sound and vibration issues can be rectified.  The SPS elastomer core greatly reduces the propagation of vibration and noise through steel structure. Read more about the use of SPS for noise and vibration damping aboard a RoPax ferry

Additionally, a ‘thin core’ arrangement (15mm Elastocore centre) plus an aluminium top plate to reduce weight better than ‘Waffle Deck’ or other epoxy coating arrangements.
