Client: Stolt Kestrel
Application: Steam pipe on tanker
Location: Bremerhaven on Germans North Sea coast
Coating Used: Mascoat Industrial-DTI
Thickness: 140 mils (3.5 mm)
Reason for Application: Corrosion Under Insulation (CUI)


Applicator Rickmers-Lloyd Shipyard Company is strategically located in Bremerhaven on Germany’s North Sea coast. The company has more than 100 years experience in repair, conversion, modernization, and completion of every size ship.


The Stolt Kestrel tanker, which came in for maintenance, needed a solution for the steam pipes that had severe problems with CUI because marine environmental conditions cause sulfites and chlorides under traditional insulation systems with iron containing materials.


The company chose a more durable solution, Mascoat Industrial-DTI (DTI), instead of traditional fiber material combined with cladding, to prevent further CUI. The steam pipes, which are 320°F (160°C) in service, got a full surface preparation with a new inorganic zinc system combined with 140 mils (3.5 mm) of DTI.


This standalone system gave them a combination of advantages, namely energy retention, personnel protection against burn hazards, and no CUI problems.
