Title (EN) APPARATUS FOR FORMING TUBULAR CONNECTIONS AND METHOD OF USE
(FR) APPAREIL DE FORMATION DE RACCORDEMENTS TUBULAIRES ET PROCÉDÉ D'UTILISATION
Abstract:
(EN) The invention in one aspect provides an apparatus and method for forming a connection between an inner tubular and a caisson of an offshore structure. The apparatus comprises a mandrel, and a seal arrangement disposed on the mandrel and configured to create a seal between the mandrel and an inner surface of an inner tubular in which the apparatus is located. The seal arrangement comprises first and second cup seals, axially separated on the mandrel, and configured to define a substantially annular volume between the mandrel and the inner tubular in use. A pressure transmission path delivers a pressurised fluid to the annular volume, and the apparatus is configured to pressurise the annular volume and thereby expand the inner tubular in a radial direction and into contact with the caisson to form a connection between the inner tubular and the caisson.
(FR) Un aspect de l'invention concerne un appareil et un procédé pour former un raccordement entre un élément tubulaire interne et un caisson d'une structure en mer. L'appareil comprend un mandrin, et un agencement d'étanchéité disposé sur le mandrin et configuré pour créer un joint entre le mandrin et une surface interne d'un élément tubulaire interne dans lequel se trouve l'appareil. L'agencement d'étanchéité comprend des premier et second joints calottes, séparés axialement sur le mandrin, et configurés pour définir un volume sensiblement annulaire entre le mandrin et l'élément tubulaire interne lors de l'utilisation. Un trajet de transmission de pression distribue un fluide mis sous pression au volume annulaire, et l'appareil est configuré pour mettre le volume annulaire sous pression et, de ce fait, étendre l'élément tubulaire interne dans une direction radiale et en contact avec le caisson pour former un raccordement entre l'élément tubulaire interne et le caisson.
