Abstract
To compensate considerable movements between a floating unit and a seabed structure which are interconnected by a fluid line, the invention proposes to embody this fluid line in an upper catenary and a lower portion. The upper catenary is on the one hand supported by the floating structure and on the other hand by a subsurface buoy. The lower portion is on the one hand supported by the subsurface buoy and on the other hand connected to the seabed structure. This lower portion is provided with buoyancy beads. In this way it is possible that the floating structure may be displaced a considerable distance relative to the seabed structure. In addition, the system can withstand considerable environmental loading. This means that the connection between the seabed structure and floating unit can be maintained even under unfavorable conditions.
