SGT-A35 | RB211 User Group Meeting 2019
ETN’s SGT-A35 (formerly Industrial RB211) User Group Meeting was held on 7-9 May 2019 in Amsterdam, Netherlands, hosted by Shell.
The SGT-A35 User group – that ETN has initiated in 2017 – was founded to help the community to share experiences, and to highlight in a coordinated way the most widespread issues users encounter while operating or maintaining a specific type of gas turbine. The point is to create the opportunity for a direct dialogue between the Users, the OEM, the Independent Service Providers (ISP) and finally the R&D community. This independent user meeting is therefore a well-tried method for open, inclusive and constructive discussions and, ultimately, concrete results.
Venue and agenda
The SGT-A35 User Group Meeting took place at Shell’s Technology Centre in Amsterdam.
This is a unique meeting where the agenda is set by the user community of this engine.
The two-day event included:
- Discussions among Users only on top issues and topics regarding the SGT-A35 |RB211 engine family;
- Sessions with ISPs and Suppliers
- An exhibition area
