Abstract: A hybrid riser tower is disclosed with a rigid riser column and a buoyancy tank positioned to apply tension to the riser column by buoyant upthrust when the tower is in an upright orientation for use. At least one jumper support structure is attached to a side of the buoyancy tank between upper and lower ends of the buoyancy tank when the tower is oriented for use. At least one riser connection extends outside the buoyancy tank from a riser pipe of the riser column to the jumper support structure, where it connects to a flexible end fitting carried by the jumper support structure. The riser connection splays laterally moving from the riser pipe toward the jumper support structure.

Abstract: The invention relates to an alloy having high temperature mechanical strength in an oxidizing medium and comprising a carbide-precipitation-strengthened matrix containing chromium. The invention is characterized in that the alloy comprises carbides of at least one metal (M) selected from among titanium, zirconium and hafnium, said carbides also optionally containing (M?) tantalum. The invention is suitable for articles that require high temperature mechanical strength, such as for hot glass processing or production.

Abstract: Disclosed herein is a guide frame (10) for location at one or more points along the length of a riser tower structure (112,114). The riser tower structure is of a type that has an upper end supported at a depth below the sea surface and has a central core (200) with one or more conduits (220) arranged therearound extending from the seabed toward the surface. In use, the guide frame guides the conduit (s) relative to the central core, said guide frame (10) being attachable to said riser tower structure non-continuously (40,50), thereby not becoming an integral part of said riser tower structure. Also disclosed is a riser tower comprising such guide frames.
