An apparatus and method for compensating for subsea pressure on a hydraulic circuit, said apparatus comprising a body (42) defining a chamber (44) having a piston (50) slideably arranged therein, the body (42) having an opening (48) in front of an outer side (54) of said piston (50), hydraulic fluid (43) in the chamber 10 (44) behind an interior side (56) of said piston (50), said hydraulic fluid (43) for communication with a hydraulic circuit (45, 46, 47) characterised in that said piston (50) has a piston rod (60) connected to said piston (50) and slideably arranged in a piston rod chamber (72) and a pressure apparatus (80) for applying fluid pressure in said piston rod chamber (72) to the second piston rod (60), thus maintaining a slightly higher pressure in the hydraulic circuit than the pressure of the water immediately surrounding the hydraulic circuit. The hydraulic circuit is preferably a closed loop hydraulic circuit. The pressure apparatus may provide a positive or negative pressure as desired.
L~invention a pour objet un appareil et un procédé pour compenser la pression sous-marine sur un circuit hydraulique, ledit appareil comprenant un corps (42) définissant une chambre (44) dans laquelle un piston (50) est placé de manière coulissante, le corps (42) présentant une ouverture (48) à l~avant d~une face externe (54) dudit piston (50) et un fluide hydraulique (43) dans la chambre (44) derrière une face interne (56) dudit piston (50) pour communication avec un circuit hydraulique (45, 46, 47) et étant caractérisé en ce que ledit piston (50) possède une tige (60) reliée audit piston (50) et disposée de manière coulissante dans une chambre (72) et un appareil de pression (80) pour l~application d~une pression du fluide dans ladite chambre de tige de piston (72) à la seconde tige de piston (60), de manière à maintenir une pression légèrement supérieure dans le circuit hydraulique (45, 46, 47) à la pression de l~eau l~entourant. Le circuit hydraulique est de préférence un circuit fermé en boucle. L~appareil de pression (80) peut produire à volonté une pression positive ou négative.
