During wellhead system installation, manual
techniques are commonly employed to verify
correct placement of each component. Drawing
inferences by using space-outs and weight
indications, inspecting marks, and opening
outlets to check marks on internal components
increases likelihood of errors and HSE risk.
An operator decided to try Cameron’s software-based
solution that provides real-time feedback
for equipment positioning and can be used on
any wellhead. The nonintrusive, modular package
comprises a human machine interface (HMI)
device or laptop with automated workflows,
position sensors, and a data transmission unit.
The sensors were placed on the wellhead
and communicated with the software, which
analyzed the equipment position and sent binary
signals (green or red) to the HMI outside the
hazardous zone. These signals indicated whether
the hanger or packoff assembly was successfully
landed, eliminating NPT due to misalignment,
debris, or both.
