Paper Abstract

The correct alignment and setting of the components inside subsea wellheads is critical to ensure that all seals perform at the high pressures found in subsea hydrocarbon production systems. Of particular importance is the alignment of the tubing hanger and how it engages with the subsea trees or wellhead. The tubing hanger supports the production tubing string with carries the hydrocarbon from the reservoir and experiences pressures up to 15 kPsi. Full and correct engagement of the locking and sealing mechanisms of the tubing hanger is critical in containing the production fluids. Here we present the results of a trial of a laser profiler to assess the interior surfaces of a wellhead. The scanner has been shown to be capable of effectively inspecting the interior surface of the wellhead for damage and measuring the interior structures to allow the tubing hanger to be installed correctly.
