Flow diverter tool assembly and methods of using same

A flow diverter tool assembly is employed for flushing debris from a portion of the bore of a subsea production tree. The flow diverter tool assembly has a housing having a passageway there-through and a seal disposed on an exterior surface of the housing. The seal contacts the inner wall surface of the bore of the production tree, dividing a lower portion of the bore below the seal from an upper portion of the bore above the seal. One or more outlets from the passageway through the exterior surface are disposed along the housing below the seal. A bypass device such as a slip-joint is disposed above the seal to facilitate removal of the flow diverter tool assembly from the bore of the production tree after its use.
