Abstract: A handling device (1) for an installable and retrievable subsea apparatus (2) to engage a docking device (3) on a subsea installation, the docking device (3) having a pair of engagement members (4, 5). The device (1) is provided with a top member (6) and a pair of engagement arms (7, 8) depending therefrom to extend along the outside of the apparatus (2). Each of the arms (7, 8) at a free end thereof is provided with a hook (7?, 8?) configured to engage in releasable way the engagement members (4; 5). A rotatable handle (9) is located above the top member (6) and has an integral or linked stem (10) which extends through the top member (6) and is pivotally linked to a top region of the apparatus (2). The handle (9) is able to operate the engagement arms (7, 8) relative to the engagement members (4,5).

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 1,1 section (4?) and being associated with respective sub-unit (6?, 6?).
