I think for sea launching dynamic positioning can be used the engines should be powerful enough and you have more control on under which sea conditions you’ll be operating under. At that point the exhaust might be the biggest problem but if you design your exhaust deflectors correctly they themselves can be used for station keeping as long as you don’t vent everything from one side of the rig I think you’ll be all right. Deep enough ballast tanks and dynamic positioning should be more than stable enough for launch. I think the rigs in the med use dynamic positioning even on a semi permanent basis because the Mediterranean is much calmer compared to say the North Sea or even the Atlantic.
