Bushing preparation
All operators involved in components unpacking and assembly have to be careful not to damage the objects.
During the unpacking operation, it is necessary to check that all components supplied by GE Energy
Connections RPV are available and not damaged during the transportation.
All incoming goods must be stored in a covered area and prepared for the installation.
At the arrival, the crate must be inspected. Any damage of the crate or indication of the visual external shock
indicator (see
Figure 3
) must be reported to the Foreman and GE Energy Connections RPV Supervisor.
