A method of drilling and producing from an offshore structure, comprising drilling a first well from the offshore structure with a drilling riser; completing the first well with a first subsurface tree; connecting the first subsurface tree to a manifold; drilling a second well from the offshore structure with a drilling riser; completing the second well with a second subsurface tree; connecting the second subsurface tree to the manifold; and connecting a production riser to the manifold and the offshore structure.

Offshore drilling and production systems and methods

There is disclosed an umbilical assembly comprising at least one elongated umbilical element, and at least one light weight, high strength reinforcing rod.

Umbilical assembly, subsea system, and methods of use

Vortex-induced vibrations of unsupported segments of subsea pipelines are reduced by providing a shroud that can be lowered onto the subsea pipeline wherein the shroud creates turbulence that interferes with vortex shedding and thereby reduces the amplitude of vibrations are reduced. The preferred shroud comprises a plurality of rods supported in vertical planes along the sides of the pipeline. Installation can be performed without the use of divers.
