Depends.
First of all, leaving the mooring to help save a live is always the
prime choice as opposed to pitying the poor lonesome divers ascending on
the lone mooring.

Then.
poor communication:
 Pilot to ship ( amongst a bunch of some all likealikes) "heli to ship
NN.3x..nn hey can you identify yourself?
american flag..hm, colour. hmmm, hey could you displace something
discernable on yer frontdeck ( like barebosom mermaid)... and so on, or
just,:
 hey boat xx, can you pls leave mooring at xxhundred hour heading for
bearing xxxhundred?

good communication, may be bad weather:
hey boat xx, can you pls leave mooring at xxhundred hour heading for
bearing xxxhundred?

Mass inertia is helping proper operations. A moving heli is less subject
to sudden wind, a moving boat less to wave, and buoy line interference.
