Giving deference to the superior skills at your operation, do they have to circle OEI or with partial flap and TERPS?
One engine inop, flap 22....just the way the Lockheed AFM says, TERPS included.
It can be done, just follow the plot.
Just where do you train regarding circling approaches?
In the actual airplane.
Gosh, what a surprise.

We spend the bucks, crews trained...profits flow in.
Yes, I know...old fashioned, but it works.
