Zusammenfassung:	A latch and method for use is provided for latching an item of oilfield equipment. The latch has a housing (200) containing a latch member (116), and the latch member is movable between a radially engaged position in which it is engaged with the item of oilfield equipment, and a radially retracted position in which it is disengaged from the item of oilfield equipment. An actuator (118,224) is configured to drive the latch member into the radially engaged position. A second actuator (118,226) is configured to drive the latch member(116) toward the radially retracted position. The housing defines at least one slot (220), the at least one slot being arranged to allow fluids to pass therethrough while the latch member travels between the radially engaged position and the radially retracted position
