Abstract

A retrievable subsea apparatus (1) with a pressure and volume compensating system, the apparatus comprising: a housing (1') having in its interior a control system (9) located in a first section (3) thereof and an operating unit (6) located in a second section (4) thereof. The apparatus further comprises a penetrator (2) which constitutes an interface between the first section (3) and the second section (4), wherein the first section (3) has a substantially constant first pressure. An external pressure compensator (5, 5') is associated with the second section (4) having a second pressure. The operating unit (6) comprises at least a first sub-unit (6') and at least a second sub-unit (6"). The second section (4) is subdivided into at least a first sub-section (4') and at least a second sub-section (4") which is sealed off from the first section (4') and being associated with respective sub-unit (6', 6").
