Abstract
Interface arrangement for components such as valves and control units incorporated in subsea stations particularly for hydrocarbon production, in which the 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 unit (ROT) havign a mating interface arrangement to cooperate with that of the components. The upper part of the component, which is mounted for retrieval in a substantially vertical direction from its fixed position on the subsea station, is provided with central handling means and one or more coupling members. The handling means and the coupling members are adapted to cooperated with respective mating means and members provided on the ROT. Moreover, the handling means is dimensioned for lifting and transporting the component suspended from the ROT. The coupling members 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 an operative position connection to the component through the handling means, so as to effect an operation on the component, for example locki…
