rack and pinion or hydraulic ram and locking pins
(OP)
Hey all,
I am in need of a system to lift a ~300ton object off the sea floor. I have had suggestions of using a rack and pinion system driven by an electronic/hydraulic rotary drive unit, or using a multiple stage hydraulic ram with locking pins.
What are the pros and cons of the two options?
Thanks,
Sam

How deep? Lift how far? For what purpose? How often? Portable? Remote control or direct? I could go on and on with questions. You haven't begun to give enough information to get any kind of reliable advice. Not that I would base my design on the opinions of some guys in a forum.
I see that you are Civil/Environmental. So its understandable if you don't have the mechanical design skills or judgment this job requires. You need a highly experienced mechanical design engineer (preferably experienced in underwater operations) on your staff working directly with you on this.

Seems a little more practical than bringing it up to surface mechanically speaking.
