Title (EN) AUXILIARY SUBSURFACE COMPENSATOR
(FR) COMPENSATEUR SOUTERRAIN AUXILIAIRE
Abstract:
(EN) Force-dampening arrangement (100) for dampening forces between two interconnectable parts in a tube string, of which interconnectable parts a lower part (101) is connected to the upper end of a string element (105, 3a) extending into a subsea well (5) and an upper part (103) is suspended from a floating surface installation (1) through at least one suspension element (3b) extending up to said surface installation. The force-dampening arrangement (100) is connected to the tube string above a string-portion (3a) extending into said subsea well, and below at least a portion of said suspension element (3b). The force dampening arrangement (100) exhibits an upper and lower section (109, 111) that are vertically movable in relation to each other, thereby yielding for impact forces between said interconnectable upper and lower parts (103, 101) resulting from vertical heave movement of said portion of suspension elements (3b) moving vertically in respect of the string element (3a).
(FR) Dispositif amortisseur (100) destiné à amortir les forces entre deux éléments interconnectables dans une colonne de tubage, éléments dont la partie inférieure (101) est raccordée à l'extrémité supérieure d'un élément de la colonne de tubage (105, 3a) pénétrant dans un forage sous-marin (5) et dont la partie supérieure (103) est suspendue à une installation de surface flottante (1) par au moins un élément de suspension (3b) tourné orienté vers le haut en direction de ladite installation de surface. Le dispositif amortisseur (100) est relié à la colonne de tubage au-dessus d'une partie de colonne (3a) qui pénètre dans le forage sous-marin et au-dessous d'au moins une partie dudit élément de suspension (3b). Le dispositif amortisseur de force (100) comporte au moins une section haute et une section basse (109, 111), mobiles verticalement l'une par rapport à l'autre, ce qui génère des forces d'impact entre les éléments interconnectables supérieur et inferieur (103, 101), d'où un mouvement de soulèvement de ladite partie des éléments de suspension (3b) se déplaçant verticalement par rapport à l'élément de colonne de tubage (3a).
