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

For over 21 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 for Maritime and Offshore is an intelligent structural composite designed to protect POB safety, eliminate the need for dry-docking and permit the use of innovative cold work repair methods—all while saving you time and money.

For cost-effective maritime repair and modification, the clear choice is SPS.


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

Instead of conventional ‘crop & renew’, the use of structural composites such as SPS® (Sandwich Plate System) for structural reinstatements and reinforcements is forward-looking and 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

SPS for Maritime Vessels

  • prevents damage including crack initiation
  • can be undertaken in restricted or limited access areas
  • can be undertaken without removing insulation and service runs
  • reduces costly downtime and schedule disruption
  • minimises project risk and lost time incidents (LTIs)
  • can be carried out while the vessel is in-service, eliminating the need for drydocking

SPS for Offshore Assets

  • requires up to 90% less labour and 56% less steel than conventional techniques
  • is up to 11x less expensive and 3x faster than a steel crop and renewal
  • eliminates the need for dive boats and underwater cofferdams
  • allows work in adjacent areas to continue in parallel
  • helps shorten project schedules as the structure remains intact
  • reuses the existing corroded plating as one side of the composite
  • ensures enhanced fatigue resistance and extended service life

How does SPS compare to other repair solutions?


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.

Andrea GalterOperability Lead Engineer for SBM Offshore

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.

Ian Nash

SPS Technology Marine and
Offshore Business Manager

As Marine & Offshore Business Manager for SPS Technology, Ian Nash works closely with a wide range of global clients, advising on class-approved composite structural steel repairs.

With the SPS Technology team, Ian is on a quest to ensure composite structural repairs are seen as standard repair options and no longer a new technology.

Ian has worked on projects globally with most of the oil majors and taken part in several maritime research and development projects.

After studying Engineering at A level, Ian joined the Royal Navy, qualified as Lead Marine Engineer on Destroyers, and studied Marine Engineering at Portsmouth University before beginning his 15 years (and counting) journey with SPS Technology.

Ian is delighted that the “Human Factor” of face-to-face meetings in person, building relationships and sharing experiences is slowly coming back to the maritime and offshore industry. Having recently attended meetings in person with new and existing customers to share technological advances of our products, it has become clear what originally manifested as uncertainty and fear in our industry has been replaced by resilience and determination to succeed.
