Electro-hydraulic Umbilicals - Hoses
Designed and tested to withstand harsh environmental conditions in water depths as deep as 2,500 meters in both static and dynamic applications, these umbilicals comprise the following typical functions:
- High-pressure hydraulic control hoses;
- High-pressure chemical injection hoses;
- Electric control cable (optical fibre control core can be provided as an option, on demand).
High-pressure hydraulic control hoses are made of a nylon extruded liner, reinforced with a polyaramid braid and sheathed with an extruded polyurethane layer.
Chemical and ethanol injection hoses are similar to control hoses, and may also be provided with an internal anti-collapse metallic interlocking reinforcement, depending on the system's operating conditions such as internal fluid density and water depth.
Electrical control cables are insulated and jacketed with high-performance compounds. Electrical cable design and performance can meet the most demanding and specific system requirements.
The umbilical components are assembled and sheathed with a polymeric extruded layer and then armoured with a counter-helix double-layer flat steel wire armor, to virtually eliminate any torsional tendency due to installation/operation stresses, and improve the umbilical hydrodynamic stability.
The outer jacket is designed to provide excellent performance in terms of abrasion and crushing, besides UV resistance.
