Patent ID: 10309161

Abstract:
The present invention relates to systems for securing connectors of risers in petroleum production units. In this scenario, the present invention provides an autonomous system for securing a riser support, said system comprising (i) a riser support (32) connected at its bottom end to a submerged riser (34) and at its upper end to a tensioning element (30), (ii) a supporting ledge (20) comprising a through-hole (22) through which the tensioning element (30) and at least part of the riser support (32) pass, (iii) a securing device (40) located on the supporting ledge (20), said securing device (40) sliding relative to the supporting ledge (20) and driven by an actuator (48), wherein the securing device (40) slides between an unlocked position and a locked position on the through-hole (22), wherein, in the locked position, the securing device (40) can engage with locking in a connector (38) of the riser support (32) after the connector (38) has passed through the through-hole (22) of the supporting ledge (20). The present invention further provides an autonomous method for securing a riser support associated with the system described above.
