INSTALLATION OF SUBSEA RISERS

Resumen de: US20260201755A1

0000 A steep-configuration subsea riser is installed by supporting an elongate flexible riser element underwater with a portion of the riser element ascending from the seabed. The ascending portion of the riser element is captured in a guide formation of an anchoring support. The anchoring support is then moved to a final position on the seabed while the riser element remains captured by the guide formation. When in the final position, the anchoring support anchors the riser element in a steep configuration. The anchoring support is lowered to the riser element to capture the riser element and is further lowered to the final position after capturing the riser element. In this way, after installing the riser element in a lazy configuration, capturing the ascending portion of the riser element and moving the anchoring support to the final position, the riser element is reconfigured into a steep configuration.
