CA 2644349
A mobile, year-round drilling system (MYADS) for drilling offshore wells and/or performing other offshore activities at multiple, successive locations in an arctic or sub-arctic environment is provided. The present invention combines the ability to move to different locations and the strength to resist ice loading when on location and when ice-covering is present in the arctic or sub-arctic environment. The MYADS applies a multiple leg "jack-up" concept in which supporting legs are lowered through a hull to touch down on the seabed and elevate the hull out of the water.
L'invention concerne un système de forage pendant toute l'année, mobile (MYADS) pour le forage de puits en mer et/ou la mise en oeuvre d'autres activités en mer à de multiples emplacements successifs dans un environnement arctique ou subarctique. La présente invention combine la capacité à se déplacer vers différents emplacements et la force à résister à la charge de glace lorsqu'elle est en place et lorsqu'un recouvrement de glace est présent dans l'environnement arctique ou subarctique. Le MYADS applique un concept de "plateforme auto-élévatrice" à pieds multiples dans lequel des jambes de support sont descendus à travers une coque de manière à toucher le fond marin et élever la coque hors de l'eau.
