Popular Coldwork Applications
FPSO Main Deck
Reinstatement
Main deck in way of crude oil tank was corroded beyond class limit.
Using SPS technology, deck reinstatement was conducted with 57% less manpower in a 40% faster installation time compared to traditional crop and renewal processes.
FPSO Main Deck Reinstatement

Using Sandwich Plate System technology, deck reinstatement was conducted with 57% less manpower in a 40% faster installation time compared to traditional crop and renewal processes.
Bulkhead Plate, Shell Plates, Web and Longitudinal Ship Repair
The traditional ship repair would require hotwork, diver and cofferdam.
With cold repair, there was no need for any hot work in tank, cutting through of bulkheads and side shell hull and time-costly leakage tests, saving the FSO precious man hours, giving them a reliable yet competitive service.
Bottom Plate and Tank Top Plate Ship Repair
A Floating Production Storage and Offloading (FPSO) vessel, required tank top reinstatement work within the inner bottom of a cargo oil tank.
As a result, FPSO experienced zero downtime, and avoided massive opportunity costs as the crude oil tank would need to be cleaned and production would be stopped.

Frequently Asked Questions on Sandwich Plate System Technology
1. What are Sandwich Plate System Processes?
Step 1 – Surface Preparation
The surfaces of new and existing plate, that form the internal SPS cavity, are treated to remove paint and rust and to provide the required surface roughness and cleanliness. This provides the required surface finish for the elastomer to bond effectively when injected. Grit blasting is a reliable method of providing the required surface preparation. Slurry or high pressure water jet may be acceptable, depending on the application, to be agreed.
Step 2 – Fitting of Perimeter Bars
Flat bars of thickness equal to the nominal elastomer core thickness are fitted to create boundaries for the injection cavities. These are welded or adhered to the existing structure. In some cases, the bars may be fitted before blasting the surface of the existing plating.
Step 3 Fitting the Top Plate
Top plates are positioned and welded to the perimeter bars following a thorough QA check, along with any required fittings; such as foundations, pad eyes and lashing pots/sockets.
Step 4 Injection of Elastomer
Mixing and injection of elastomer is carried out under controlled conditions. This may be undertaken by various methods and equipment (impingement mixing, shear mixing, ‘hand mix’) depending on the quantity of material to be dispensed and location of the repair.
