METHODS FOR INSTALLING RISERS IN A FLUID INJECTION SYSTEM

A fluid injection system contains a buoy (170) for connecting with a vessel to receive fluid therefrom. At least one fluid-transporting riser (171) connects the buoy (170) with a subsea template arranged on the seabed at a wellhead for a drill hole to a subterranean void. Each riser (171) is detacha...

Zusammenfassung:	A fluid injection system contains a buoy (170) for connecting with a vessel to receive fluid therefrom. At least one fluid-transporting riser (171) connects the buoy (170) with a subsea template arranged on the seabed at a wellhead for a drill hole to a subterranean void. Each riser (171) is detachably connected to a bottom surface of the buoy (170) by means of a connector arrangement (210) containing: a buoy guide member (510) configured to automatically steer a connector member (570) in a head end (300) of a riser to be connected (171) to the buoy (170), which head end (300) is moved towards the buoy guide member (510); a mating member (550) configured to attach a first sealing surface of the connector member (570) to a second sealing surface of the buoy guide member (510) when said head end (300) has been moved such that the connector member (570) contacts the buoy guide member (510), and a locking member (560) configured to lock the first and second sealing surfaces to one another when said surfaces are aligned with one another.
