An apparatus, system and method of manufacturing a marine riser constructed of an aluminium alloy having a high strength-to-weight ratio is provided. The inventive riser apparatus comprises a plurality of riser sections coupled serially end-to-end, wherein each of the riser section comprises a pipe having a first end and a second end, a first flanged coupling welded to the first end of the pipe, and a second flanged coupling welded to the second end of the pipe, wherein the pipe is constructed of an aluminium alloy having a strength- to-weight ratio greater than that of steel. The riser apparatus may optionally include one or more auxiliary lines providing hydraulic communication with a blowout preventer.

L'invention concerne un dispositif, un système et un procédé permettant de produire un tube prolongateur marin formé d'un alliage d'aluminium présentant un rapport solidité/poids élevé. Le tube prolongateur décrit comprend une pluralité de sections de tube raccordées en série, bout à bout. Chaque section de tube comprend un conduit présentant une première et une seconde extrémité, un premier raccord à bride assemblé par soudage sur la première extrémité du conduit, et un second raccord à bride soudé sur la seconde extrémité du conduit, le conduit étant produit dans un alliage d'aluminium présentant un rapport solidité/poids supérieur à celui de l'acier. Ce tube prolongateur peut éventuellement comprendre une ou plusieurs lignes auxiliaires établissant une connexion hydraulique avec un bloc obturateur.
