Принадлежит: Lylyn Hingle Stockstill

A pipe reeling system can be positioned in a location adjacent a dock to prepare spools of wound pipeline. The pipe segments are delivered to the facility from a steel mill or other manufacturer and placed on one or more pipe storage racks in a first orientation. The pipe segments are then moved to an elevated pipe feeding bed, from which they are fed in a second direction, transverse to the first direction through a plurality of weld stations. The pipe segments welded end-to-end form a continuous pipe unit, which is transferred to a spool and wound thereon. The spools can be prepared in advance of a request from a pipeline operator and stored in the facility on the reels until required.

Installation of Subsea Risers

Номер: US20220065049A1
Автор: Bittar Romeu Nelson, Lage Bormann Flavio, Nogueira Barcellos Marcio, Ramiro Amorim Andre, Sahonero Rodrigues Daniel
Принадлежит:

A method of installing a subsea riser includes placing an elongate negatively-buoyant support on the seabed and, when laying the riser on the seabed, guiding a riser portion onto the support to extend along and be cradled by the support. A hogbend region of the riser is then formed by conferring positive buoyancy on the support to lift the support and the riser portion away from the seabed. An element of the support includes a riser support disposed in a longitudinally extending open-ended gap between buoyancy volumes disposed on opposite sides of the gap. Coupling formations such as hinge portions can couple the element to a like element. When so coupled, the gaps of those elements align to define an upwardly opening, longitudinally extending groove to receive the riser.

Pipe Spooling for Reel-Lay Operations

Номер: US20220065366A1
Автор: Rodrigues Freire Neto Irio, Sahonero Rodrigues Daniel
Принадлежит:

Lined pipelines with different inner diameters are spooled successively onto a reel while their constituent pipe stalks are cyclically pressurised internally to combat wrinkling of the liner. A first, variable diameter pig is advanced to a trailing end of a first pipeline. A transition joint is attached to the trailing end of the first pipeline to effect a transition from the inner diameter of the first pipeline to the different inner diameter of a second pipeline. A leading end of the second pipeline, containing a second pig, is attached to the transition joint. The first pig is driven through the transition joint into the second pipeline. The diameter of the first pig changes to match the inner diameter of the second pipeline. The first and second pigs are then driven along the second pipeline when assembling the second pipeline from a succession of pipe stalks.
