Relocated gas turbine and existing inlet duct blasting/painting issue
Relocated gas turbine and existing inlet duct blasting/painting issue
(OP)
We are erecting a owner supplied relocated gas turbine and its used air inlet duct at a new project site. While the Owner wants us to blast and repaint the used duct that's now erected adjacent to the turbine he has brought up the concern that dust/particles left on inlet duct associated with blasting process could potentially make its way into the turbine. Looking for recommendations/solutions as to how this can be accounted for.

This sounds like an "after-the-fact" Client Originated Change Order.
You need to prepare a proper Change Order Notice complete with a full description for:
(a) Disassembly of the Duct Work from its current location
(b) Transport to a proper Paint Shop
(c) Sand Blast and Painting
(d) Transport back from the Paint Shop
(e) Reinstall the Duct Work
You need to include an Estimate for all:
-- Time?
-- Material?
-- Services required?
Before starting, get the Clients Signature of approval for the Extra
Sometimes its possible to do all the right things and still get bad results

Do NOT run the GT when blasting nearby.

Like crushed dry ice.
The process is already worked out, and has been offered commercially.
Search on, e.g., CO2 blasting.
