| 摘要 |
A subsea equipment ( 1 ) used for natural gas or crude oil production, such as a subsea actuator ( 2 ) for a valve, a restrictor or the like, a control module or other means, comprises at least an oil-filled first component ( 3 ) and a compensator unit ( 4 ) which is associated with said first component and which is in fluid communication therewith for pressure compensation. To improve such a subsea equipment in a structurally simple manner in such a way that it is capable of functioning and that pressure compensation is still possible, even if the associated compensator unit is damaged or fails to operate, a second compensator unit ( 5 ) is in fluid communication with said first component ( 3 ) or said first compensator unit ( 4 ) for pressure compensation.
