<p>A method and system for retrieving a wear bushing from within a subsea wellhead assembly. The system includes a retrieval tool deployable on a wireline that inserts within the bushing. Latches on the tool radially project outwards and mate with a groove on the bushing inner surface. A hydraulically actuated jack is included with the tool and projects downward to the wellhead assembly to pull the bushing from its temporary coupling in the wellhead assembly. A remotely operated vehicle can be used to assist deploying the tool and for supplying hydraulics and/or control for operating the latch and the jack.</p> |
