Pipe Spool Replacement

Global Scanning Solutions was contracted by Subsea7 to provide dimensional control survey measurements for a series of fabricated pipe spools. In order to achieve the project requirements it was proposed that the pipe spools be surveyed using conventional dimensional control surveying methodology.

The primary objective of the project was to determine potential deformation in the outer rim of the umbilical reels and to develop 3D CAD models of the centre hub assemblies with the ability and functionality to determine hydraulic drive equipment interfacing clearance.

Key deliverables included;

• Dimensional survey report
• 3D CAD as-built model
• Registered point cloud data
• Plan and section general arrangement drawings

A team of 2 surveyors were mobilised to this project, with the team completing the dimensional control survey and the 3D laser scanning. Our 3D modelling team were tasked with developing a 3D as-built model and offset general arrangements.
