Isn’t the Radio Operator’s position on a rig actually now days a clerk? Once upon a time when the rigs needed to communicate via SSB with shore, the R/O did actually operate radios. Now with megabandwidth V-Sat systems alot of rigs have either eliminated R/O’s or changed their job description.
The R/O’s on rigs I been on mainly keep POB lists and fill out helicopter manifests. Certainly not a technical job.
