Wear bushing deployment and retrieval tool for subsea wellhead

An apparatus for deployment and retrieval of a wear bushing in a wellhead with a drillstring, the wear bushing having a first through-bore and having a first profile defined in the first through-bore, the apparatus comprising:

• an adapter bushing supported in the first through-bore of the wear bushing at the first profile, the adapter bushing having a second through-bore and having a second profile defined in the second through-bore;
• a mandrel configured to connect to the drillstring and position in the second through-bore of the adapter bushing, the mandrel having an actuator and defining a flowbore therethrough for communicating with the drillstring;
• and
• a plurality of arms disposed on the mandrel, the arms being selectively movable between a retracted condition and an extended condition on the mandrel in response to the actuator, a distal end on each of the arms in the extended condition being configured to engage the second profile of the adapter bushing, the arms being configured to support the wear bushing on the mandrel in uphole and downhole directions.

A method for running a wear bushing in a wellhead with a drillstring, the wear bushing having a through-bore, the method comprising:

• supporting the wear bushing in uphole and downhole directions on a plurality of arms of a running tool inside the through-bore of the wear bushing and disposed on the drillstring by supporting the wear bushing (i) on a shoulder disposed on each arm and (ii) on a catch biased to extend from each arm;
• landing the wear bushing in the wellhead with the running tool on the drillstring;
• retracting the arms movable from an extended condition to a retracted condition on the running tool;
• and
• running in the drillstring and the running tool further through the wellhead.
