OFFSHORE STRUCTURES
Advantages
TENSA technologies applied in offshore structures are aimed to:
- Strengthen and confine concrete basement structures, walls, towers, roofs and decks
- Increase concrete performance and structure robustness under external sea actions
Basement can be completely post tensioned with the use of strand tendons or bars.
Concrete towers are usually post tensioned.
Post tensioning plays a key role with vertical or annular (looped shape) tendons, creating a deep net of compression forces to the structure.
Several kind of solutions can be adopted for tendons path, including use of U shaped tendons and also bonded end tendons.
Concrete walls are also usually post-tensioned, designing structures as reinforced shells.
Post tensioning plays a key role with vertical or annular (looped shape) tendons, creating a deep net of compression forces to the structure.
Top deck and roofs may be post-tensioned with solutions up to create an orthotropic shell, with tendons placed in several layers deeply connected.
