AI Technical Summary
In situations where the working space of a pipelaying vessel is confined, achieving effective calibration of the digital X-ray device becomes a challenge.
A split-type digital X-ray calibration device suitable for subsea pipelines was designed, including an arched splicing leg that fits into a support platform to form a clearance space for the insertion of the subsea pipeline, and a hoisting assembly and calibration structure to achieve rapid assembly and disassembly and accurate calibration.
The device can be quickly assembled and disassembled in the narrow working space of the pipelaying vessel, ensuring the positioning accuracy of the pipeline without damaging the anti-corrosion layer, meeting the calibration requirements of the digital X-ray device, and facilitating dynamic transportation.
