PHI is the largest, but Air Log & Era aren't too far behind. None has any excess capacity, either in pilots or aircraft. Era has been hard-pressed to cover all its jobs since winning the MMS contract, and Air Log has very few spare aircraft, just about enough to cover normal maintenance downtime and some ad hocs. None of the competitors has any chance at all of covering even a small percentage of PHI's work. Neither the aircraft nor the pilots exist, and all the GOM companies have been hiring and buying aircraft at the highest rate they can, for some time. Crew changes for PHI customers are being done mostly by boat, and riding a boat 100+NM doesn't put the hands in the mood to do a lot of work right away. The customers are getting restless.
