Abstract
A connection arrangement for subsea connection of at least a first fluid conduit to a second fluid conduit. A supporting unit displaceably supports the connection arrangement against a supporting surface. A coupling device couples and secures the fluid conduits to the connection arrangement thereby interconnecting the fluid conduits to each other. A frame carries the coupling device and is slideably and/or pivotably mounted to the supporting unit so as to allow the frame and the associated coupling device to slide and/or pivot in relation to the supporting unit.
Claims12
A connection arrangement for subsea connection of at least a first fluid conduit comprising a first termination hub to a second fluid conduit comprising a second termination hub, the connection arrangement comprising:
- a supporting unit designed as a sledge for displaceably supporting the connection arrangement against a seabed so as to allow the entire connection arrangement to slide along the seabed via the supporting unit by sliding the supporting unit on the seabed;
- a coupling device configured to couple and secure said fluid conduits to the connection arrangement so as to thereby interconnect the fluid conduits to each other, the coupling device comprising an interconnecting pipe, a first hub configured to mate with the first termination hub, a second hub configured to mate with the second termination hub, a first clamping member arranged at the first hub to clamp together the first hub and the first termination hub, and a second clamping member arranged at the second hub to clamp together the second hub and the second termination hub, the first hub and the second hub being arranged at opposite ends of the coupling device and being connected to each other via the interconnecting pipe;
- and
- a frame configured to carry the coupling device, the frame being slideably and pivotably mounted to the supporting unit so as to allow the frame and the associated coupling device to slide and pivot in relation to the supporting unit.
