Growing up in Louisiana that seems like an odd way to get divers to the rig. We do a lot of rig diving. It doesn't require preauthorization as most captains know which rigs have lots of work traffic and which don't. We use something called rig hooks. It's a hook that usually is temporarily attached to a mooring pole. You get close to the rig and hook the hook to a piling, then pull off the pole, leaving the hook and mooring line attached to the rig piling. There is also a rope or a cable that allows you to detach the hook without pulling back up to the rig (in order to avoid bashing up against the structure in rough seas). In Louisiana most of the time the boats just use 1 hook, divers drop off the transom of the boat, and pull themselves up a line to the front of the boat and then swim to the rig. If the current is ripping or there's a reason to not allow the rear of the boat to be away from the rig, the captain can use two rig hooks, one to the front and one to the back of the boat. Then the back can stay closer to the rig and the divers don't have to swim over to it. We get some pretty bad currents going through the rigs, but I've still never seen a captain back up to one. Maybe the rigs are a little different there. We're allowed to dive on the outside of the rig structure, but asked to not stray off the rig.
It gets worse: from my experience, the boats always drop off divers on the same side of the rigs (again, most likely rig imposed rule). If the current pushes the boat towards the rig, call it a bad luck day.
Did I mention that these are considered advanced dives (some are essentially bottomless)?
But again, before the Conception tragedy, I was going to sleep in the bunk room without thinking about fire or flooding.
