Tubing Hanger Port Inspection Tool

Design and manufacture of a tool used to inspect damage to a tubing hanger port

The Challenge:

Our client engaged us to design and manufacture a tool to provide an effective, yet cost-efficient, method of inspecting damage on the annulus bore of their deployed tubing hanger. The timeline for the project was extremely short, at just 7 days from contact to delivery.

What We Did:

Astrimar proposed a solution that featured a dummy stab with sacrificial seals that would be inserted into the bore and inspected on recovery to assess the extent of the damage. Rough and fine alignment of the tool was provided by the circular profile interface with the tubing hanger, and with interfacing directly with the tubing hanger keyway. The stab would be ROV operated to the deployed depth. Once aligned and mounted onto the tubing hanger, a J-slot arrangement would then be operated by the ROV to insert the dummy stab into the TH port. Upon recovery, the sacrificial seals could be inspected for any signs of damage incurred from the damaged tubing hanger. Astrimar’s scope included conceptual and detailed engineering design, production of manufacturing and interface drawings, and supply of hardware.
