CONTROLLABLE CALIPER

摘要

An embodiment of the invention is directed to an electronic caliper which combines positioning and measurement in one unit without the use of hydraulics for subsea use. In certain embodiments, several attachments can be affixed to accommodate a range of measurement tasks. In a preferred embodiment, one jaw is adjustable and the other, or opposing, jaw is fixed, e.g. by bolting it on to a mounting structure. The jaws typically allow for the removal and replacement of other attachments. In another embodiment, the unit communicates to computer software for position control, precise indication and clamping for adjustment. In a preferred embodiment, computer software displays all feedback via laptop computer on surface. The caliper is maneuvered to a position proximate an object and used to measure a predetermined physical characteristic of the object. The measurement can be displayed, e.g. at the surface, using a computer with control software.

主权项

1. A tool for measuring a physical dimension of an object, comprising:
a) a first rail comprising a corrosion-resistant material suitable for use subsea; b) a first jaw and a second jaw disposed about the first rail, at least one of the first or second jaws being adjustable in a predetermined plane with respect to the other of the jaws along the first rail, each jaw comprising a corrosion-resistant material suitable for use subsea; c) a non-hydraulically actuated positioner operatively connected to the adjustable jaw, the non-hydraulically actuated positioner comprising a non-hydraulic actuator operatively connected to the adjustable jaw and adapted to effect movement of the adjustable jaw; d) a measurement sensor operatively in communication with the positioner, the measurement sensor adapted to measure a predetermined physical dimension of an object disposed in-between the jaws; e) a pressure balancing compensator operatively coupled to the positioner; f) a data link connector adapted to interface to a remotely operated vehicle, the data link connector operatively in communication with the positioner and the measurement sensor; g) a power source link connector adapted to interface to a remotely operated vehicle.
