| 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
The Thermotite® product line provides superior insulation
properties in subsea pipelines for flow assurance. Thermotite®
has been used in harsh environments with operating temperatures
up to 155°C and depths of up to 2800 metres.
Flexible Installation
Thermotite® products 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.
The Thermotite® system has also been tested extensively
for tensioner clamp loads, axial shear loads and fatigue,
giving excellent performance.
Engineered Solutions
The multi-layer geometry of the Thermotite® product
allows for the use of materials with specific thermal
and mechanical properties at different locations within
the product, thus enabling optimisation of the coating
for steady or transient state operation. All materials
used in Thermotite® products have been tested extensively
with a view to thermal and physical properties, in order
to ensure predictable performance throughout the life
of the field.
Mobile Plant Technology
Bredero Shaw’s Thermotite® mobile plant technology
allows for rapid and reliable mobilizations with minimum
infrastructure. The self-contained facilities are highly
automated and include independent power generation and
re-circulated cooling water systems. Thermotite’s®
modular construction allows the flexibility of using a
wide range of materials and densities. These facilities
have been successfully mobilized in Norway, Brazil and
in various sites in North America.
Advanced Field Joint Technology
Combining the Thermotite® multi-layer system with
Bredero Shaw’s proprietary 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. |
