Abstract

Et system for intervensjon av under- vannsbrønner, omfattende et sluserør (1) som er koplet til en avlederenhet (2), og en brønntraktorenhet (12) som rommes i sluserøret (1) og er innrettet til å medbringe service- eller reparasjonskomponenter ned i og opp fra den aktuelle brønn via avlederenheten (2). Sluserøret (1) og avlederenheten (2) er anordnet på et fundament (9) på havbunnen (10) med avlederenheten (2) tilkoplet via respektive grenrør (4) til de aktuelle brønner, og mellom sluserøret (1) og avlederenheten (2) er det anordnet et magasin (3) som er innrettet til å oppta de aktuelle service- eller reparasjonskompo- nenter, slik at disse kan overføres fra magasinet til brønnen, eller omvendt, ved hjelp av traktorenhetenAn underwater well intervention system comprising a lock tube (1) connected to a diverter unit (2) and a well tractor unit (12) accommodated in the lock tube (1) and adapted to carry service or repair components down into and up from the relevant well via the diverter unit (2). The locking tube (1) and the diverter unit (2) are arranged on a foundation (9) on the seabed (10) with the diverter unit (2) connected via respective branch pipes (4) to the relevant wells, and between the locking tube (1) and the diverter unit (2). a magazine (3) is arranged to accommodate the relevant service or repair components so that they can be transferred from the magazine to the well, or vice versa, by means of the tractor unit
