Abstract: A technique facilitates a subsea operation such as a well intervention operation. A system comprises a station movably positioned at a subsea location. The station comprises a housing and a lifting arrangement mounted on the housing to enable lifting of the station and movement of the station from one subsea location to another to enable successive subsea operations. The station further comprises a docking station which may have connectors within the housing. In some applications, the station also may comprise a power lead which may be operatively connected to a subsea installation and a transceiver for communicating data to a desired location, e.g. a surface location. The docking station enables docking with an underwater vehicle used to facilitate the subsea servicing operation.

Abstract: A system and method for clean-up and subsea intervention operations in a subsea well or installation, including a light well intervention vessel configured to deploy and connect a subsea well intervention package on a subsea well or installation, and configured to perform subsea intervention operations; and an auxiliary vessel directly coupled to the same subsea well or installation and configured to receive and treat returns from the subsea well.
