There have been some interesting comments posted here and I hope that this falls into that category.
Having served with several of the commenters in this forum, including DPOJean, I do not agree with the previous Guest. Besides, he must not have used spell check either. Jean may be relatively new to the field, but he has the desire to be the best that he can be, and continuously works toward that goal.
I have worked for 3 companies as DPO, Sr. DPO, Chief Mate/Captain, as well as spending a lifetime in the military. For one of those companies, all DPO’s were licensed and there were some that were excellent DPO’s and some that were lousy. At RBFalcon, all the DPO’s were licensed and again there were excellent and some not so good. I have spent time on both Deep Seas and Enterprise where there is a combination of licensed and unlicensed personnel. I have found that the blend of licensed and unlicensed personnel to be most advantageous. Is it perfect? By no means am I saying that. It doesn’t matter a whit whether a person has a USCG license to be an excellent operator. Some companies believe that it does, but it’s not true. All it takes is the desire and work ethic to do your best, the focus on what’s important while monitoring the system, and the knowledge of what to do when the 1% of the time comes when something that requires immediate action happens.
As to having licensed personnel there, it really helps when fulfilling manning requirements while underway to have a person that knows the DP system as well as being able to stand underway watches. It does get awkward at times when the junior DPO (licensed) has more authority while underway than the Sr. DPO (unlicensed). However, if the junior and senior have a good working relationship and the junior doesn’t flaunt it, there should be no problem.
Some of the previous comments also referred to TV, reading, web surfing. I have seen the gambit of this. As DPO, I have had to monitor the screen so intently that if you even turned around in the seat, you were chastized. The powers that be there wanted you to take immediate control with joystick if anything happened. I prefer evaluating the situation before taking any corrective action. I have also had to stay near the console, but also answer all the radios, do the radars, correct charts and pubs, and do logs. I have been on vessels where the senior DPO was so engrossed in the internet that the junior had to basically stand the whole watch (and yes a couple of the commenters here are in this category). I have also been on vessels where common sense was in place and even though a tv/internet might be on, the operators knew not to get so engrossed into it that they forgot about their duties. Staring at the DP screens constantly for your entire watch is going to make you lose focus. Some vessels forbid any reading on the watch at all and have the person out of the seat working on spreadsheets for any contingency. I personally prefer a relaxed atmosphere with knowledgeable personnel, whether they be licensed or unlicensed, in control of their abilities and having their wits about them so I can feel comfortable enough to sleep at night.
