Custom coating for high-temperature
subsea operations
Bredero Shaw has developed a new
custom coating product designed to be
used for subsea pipeline components
and equipment used in high-
temperature, high-pressure situations.
The new product – network epoxy
modified olefin (NEMO) – answers the
need for a coating material to be used
on irregularly shaped parts of subsea
production systems such as bends,
spools, terminations (PLETS), jumpers
and goosenecks. The range includes
NEMO 1.1 and NEMO 2.1, and has been
successfully tested on applications
up to 120°C, with tests on-going for
130°C and 140°C. NEMO 1.1 is an
epoxy-urethane hybrid suitable for low-
pressure casting applications.
It overcomes the problems associated
with traditional PU systems, and can
be used up to a maximum continuous
operating temperature of 95°C. NEMO
2.1 also has speed and demould times
similar to PU and can handle continuous
operation up to 120°C.
NEMO is a significant addition to
Bredero Shaw’s Complete Coating
Assurance model of integrated services
for offshore pipeline coating. All three
types of subsea flow assurance
coatings, including line pipe, field joint
and custom coating, are now available
for use from wellhead to platform. The
company states that Complete Coating
Assurance creates a coating system
that reduces schedule risk, performs
at depth for decades, and reduces risk
throughout the life of the pipeline.
