Crude Oil Riser of leading international oil company in Peninsula
Malaysia.
Project
: Crude Oil Risers
Location : Seligi - Alpha Platform, Offshore Terengganu,
Malaysia.
Applicator : Allied Marine & Eng’g Services
Date of Application : August 2002
The Challenge:
The 10”
V895 Main Gas Line SEA-SED Riser on the splash zone area from
Mean Sea Level up to +18 ft have showed signs of corrosion degradation
and it needs to be repaired as soon as possible to prevent further
deterioration. The client intends to grit blast the area and needs
a coating that be applied on-line at an operating temperature
of 70°C.
Solution:
Corro-Dur
561 and Corro-Dur 258 were chosen as it is solvent-free, 100%
Solids, surface tolerant coatings, on-line application up to 90°C
operating temperature and can be applied on dry, damp, wet or
even underwater.
Result:
The Diving
Crew applied the coatings as a temporary measure which will provide
corrosion protection while test evaluations are being conducted
on the risers. They intend to replace existing riser claddings
with our Corro-Wrap composite sleeve since we have proved that
it is easier to apply than the conventional composite sleeves
they are using with the same physical and mechanical properties
at a much competitive price.
