In Proper Apostrophe Usage with Initialisms: CCS' or CCS's? the conclusion was that the trailing s is dropped when the thing's singular name ends in an s. Correct usage would then be #4, The OPS' structure.

I think there is a little more to it than that; for example my boss's house. I think the best guide is whether you actually pronounce the possessive as oh-pea-ess or oh-pea-ess-iz.

The most popular related question comes to the same conclusion.
