Abstract
Abstract A jig for positioning a work performing member relative to an installation in a medium in which said member is essentially weightless and on which installation said work performing member is to perform work, for example, changing a component, such as a valve, in an under water pipeline in which the jig has clamping means for engagement with the installation structure and for moving the jig and vehicle attached thereto longitudinally along the structure for aligning the jig and vehicle with the component in the installation upon which work is to be performed, an arm and clamp for holding the replacement component and for positioning such replacement component in the installation, and an arm and clamp for engaging and removing the component to be replaced and a remote controlled unit associated with said jig for disconnecting the component to the under water installation and the method for operating such jig.
