MT Nestosat at the Houston Ship Repair


After a technical break at the Houston Ship Repair for severe damage, the propulsion engine of MT NESTOS is no more correctly lined up. A new chocking by the mean of steel shims would take place in several weeks. Polyresine is called in emergency to bring a solution. The lining up is settled back, a formwork is built for resin shims, the resin is poured in-situ, the tightening is effected when the polymerization is achieved. The whole operation has been performed in 8 days until the Bureau Veritas deliver the new authorization to sail.


Polyresine offers reliable solutions to your problems of
installation and maintenance for the industrial applications.

    • Chocking of your installations (pumps, compressors, rails…).
    • Grouting.
  • Protection: avoid the corrosion, improve the mechanical resistance.
  • Molding of special parts pieces..

Our products and processes are adapted to the heavy industry : our resins are resistant to most of the industry fluids
(gas, hydrocarbons, chemical products…).

Chocking of a pump at the Dunkirk Arcelor Mittal steel factory.

One of the cooling pump vibrates, which occurs a connecting problem between the pump and the motor. It can lead to operating and safety troubles.

Polyresine’s teams have intervened quickly in emergency: after the pump has been settled back by Arcelor Mittal, building of formworks prior to pour the resin (1 hour polymerization) and tightening of the anchor bolts.


Polyresine works on offshore platforms for over 30 years.

  • Chocking of the installations on the offshore platforms (pump, compressor, slewing rings, cranes…).
  • Anticorrosion protection and leak tightness (coating, adhesive…).
  • Chocking of bearings, steel frame structures, locking of heavy pieces inside not machined casing.

Our products and processes are certified by the world’s leading marine certification bodies (see organizations).
