B.285 consolidation project
The B wing on the ground floor of building 866 (R-B01, R-B02, R-B03, R-B10, R-B18, R-B19, R-B20, R-B21, R-B22) is used by the SY-EPC group as a workshop for various activities:
- Mechanical works (drilling, cutting, bending, shaping, etc.),
- Small electromechanical wiring tasks,
- Integration/wiring of converters or electrical subassemblies (prototypes, small series) of large dimensions/volumes requiring the use of an overhead crane,
- Testing and validation platform for medium-power converters (20kW...400kW) with test loads (magnets) covering an area of approximately 70m2,
- Storage of screws and various manufacturing materials, temporary storage of subassemblies before integration into converters,
- Unloading dock.
Today, the area is highly congested. It is used on a daily basis for a wide range of activities, some of which are not easily compatible. Consequently, there are significant safety constraints associated with it.
The SY-EPC group needs to relocate the testing and validation of medium-power converters in order to:
- Eliminate the risks of concurrent integration/wiring and electrical testing (due to the overhead crane usage).
- Implement a specific "Safety" approach that is consistent with the testing activity, which poses a major electrical risk for personnel working nearby.
- Increase the testing capacity of the SY-EPC Group to accommodate the LS3 and LS4 projects.
- Increase the available space for integration/wiring activities at Building 866, considering the limited space in the existing area.
The SY-EPC group proposes relocating the testing platform and its loads to Building 285. The new platform will have a usable area of 315m2 compared to the insufficient existing testing area of 70m2 in Building 866.
The relocation of the platform will allow for the reconditioning of the ground floor of Building 866 into a mechanical workshop for integration/wiring and storage purposes. The space freed up by the testing platform will be repurposed for the workshop.
