Abstract
An improved system connects subsea coupling components mounted to a movable junction plate assembly and a fixed junction plate assembly of a subsea petroleum recovery tree. The connecting handle on a movable junction plate assembly is biased for locking engagement with a movable plate to manipulate the movable junction plate assembly, but may be unlocked upon engagement with the fixed junction plate assembly to permit rotation of the connecting handle and thereby threadedly connect the junction plate assemblies. An extension arm assembly for supporting the movable junction plate assembly may be pivotably mounted to a control pod assembly, with the extension arm being extendible and contractible to allow an ROV or diver to move the junction plate assembly within a preselected zone of control.
