Pilot’s legal responsibility: NOTAM  http://tfr.faa.gov/save_pages/detail_7_6876.html or FSS  A pilot could lose his/her licence if they did not check for NOTAMs and violated the TFR around the hazard.  It is not legal for anyone to operate an aircraft in the TFR designated area.

NOTICE TO MARINERS  VHF simplex channel 22A, and VHF 16 
https://www.navcen.uscg.gov/pdf/lnms/lnm17102017.pdf   I suspect that when there is no limiting sea ice, Hilcorp will have one of their support vessel intercept the idiot that goes out into Cook Inlet without a VHF radio and/or ignores the Notice to Mariners and heads towards the hazard.
