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.

Applications

Features & 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 150°C (302°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.
