| PRODUCT
DESCRIPTION |
| Thermotite® is a technologically advanced multi-layer
polypropylene insulation coating system designed for
offshore flow assurance. Thermotite® can be
designed and manufactured in a wide range
of thicknesses and layers to meet specific
performance and subsea installation requirements
for both shallow and deep water applications. |
| FEATURES
AND BENEFITS |
Superior Insulation Properties
- Provides superior insulation properties in subsea pipelines
for flow assurance.
- Has been used in harsh environments with operating
temperatures up to 155°C (319°F) and depths of up to
3000 m (9842’).
Flexible Installation
- Can be installed using all subsea laying methods including
reeling, S-lay and J-lay.
- The product is a highly mechanically resilient product and
is constructed from impact resistant ductile materials.
- Has been tested extensively for tensioner clamp
loads, axial shear loads and fatigue, giving excellent
performance.
Engineered Solutions
- The multi-layer geometry allows for the use of materials
with specific thermal and mechanical properties at different
locations within the product, enabling optimisation of
the coating for steady or transient state operation.
- All materials have been tested extensively with a view
to thermal and physical properties in order to ensure
predictable performance throughout the life of the field.
Advanced Field Joint Technology
- Combining the Thermotite® multi-layer system with
injection moulded polypropylene field joint technology
provides an integral system well-suited to reeling
applications.
- The interface between the parent coating and the field
joint infill is fused during the manufacturing process, such
that the polypropylene material becomes continuous
and is not susceptible to cracking or delamination during
deployment and operation.
- With over 50,000 joints successfully laid by reel lay on a
range of vessels, this system has proved to be a reliable
high quality product.

As density and composition are design variables with Thermotite® the figures
above
are given as general guidelines. Where there is a range
specified, the interval
is related also to the density range for the particular component. |
