Blue Marlin is a semi-submersible ship, which means that it can lower itself partly underwater to allow its cargo to move on/off. The ship is designed primarily to move oil rigs around, with this being a special case. The radar itself is actually a converted oil rig.
How do they unload that? Do they kind of just tilt it into the water, or is there a giant crane freighter ship waiting at its destination?
