A B S T R A C T : Interface arrangement for components such as valves and control units incorporated in subsea stations particularly for hydrocarbon production, in which said components during operation are mounted in fixed positions on the subsea station and are adapted to be retrieved therefrom by means of a remotely operated tool unit (ROT) having a mating interface arrangement to cooperate with that of said components. The upper part of said component (42), which is mounted for retrieval in a substantially vertical direction from its fixed position on the subsea station, is provided with central handling means (49) and one or more coupling members (48). The handling means and the coupling member(s) are adapted to cooperate with respective mating means and members (16,18A-C) provided on the ROT. Morover, the handling means is dimensioned for lifting and transporting the component suspended from the ROT. The coupling mem- ber(s) are movable up and down in relation to the handling means, when subjected to substantially vertical pull and push forces, respectively, applied from an ROT in operative position connected to the component through the handling means, so as to effect an operation on the component, for example locking or unlocking thereof with respect to the subsea station. The top of the handling means (49) is provided with ports and/or connectors (36B,37B) for hydrau- lic, pneumatic, optical or electric interconnection between said component and an ROT.
