Космос. SpaceX Super Heavy landing on a platform at sea

My take on the SpaceX Super Heavy Booster landing catch mechanism and the converted oil rig for launching. Hereby some Explanation. I changed the design of the grid fins to be more stronger with a central axis and modular grid panels for easier maintenance and possible lighter materials. This design avoids the grid panels having any contact with the ring during landing. I added fins to the bottom of the booster that can fold. I do not think they are necessary, but some commenters on my previous video insisted they are.
