Maxtork,
I like your thinking, but;
Anything that is lubricated by a fluid will need this arrangement.
A very good thing when done, as even if it becomes approved for only 30 minutes, that's 30 minutes closer to land/rig/island/rescue.
It also shows that the solutions are out there, requiring only the desire to implement them - and no I'm not suggesting that an authority should mandate a specific system, simply give the standard and let the creativity of engineering decide.
