The quality and safety of a ship management operating indicators, fundamental condition depends on the crew. Of course, the skills of the crew, the quality is first, the reasonable arrangement of the daily rest period is essential.

Now we tend to have such a consensus, on board security incidents, not the crew violation is accountability, or business the quality is not hard. The findings of the investigation of the cause of the accident, is also often true. These conclusions is the objective, but we are not overlooked a potential factor, that is, the physical condition of the parties themselves? In my opinion, the physical factors of the crew in fact is a serious hazard to affect the safety of the ship production, but often overlooked here is the degree of physical fatigue. Sailing is a hard job, "hard" duplicitous meaning of the word, did the crew can experience, and boring, the storm has almost become synonymous with seafaring, but fatigue is often no one would have thought. The crew is concerned, in addition to the work and the environment caused by physical exertion brings fatigue, fatigue due to sleep problems brings the impact is particularly severe. The Chinese Medical Association of Psychiatry of a million people sleep survey: over 40% of the people "sleep well", "sleep well" bring more than half during the day, lack of energy, dozing, 27.7 percent of people in a bad mood, 38.9% of daytime activity limitation. Sleep on the terrestrial environment is undoubtedly much better than on board. Crew sleep by the ship shake jet lag, irregular frequent in and out of port, ship noise factors, quality of sleep is self-evident, I think if a similar survey among the crew, that will not be 40% of "sleep sleep" the ability to turn a bounded operator.

3, April 2010, the Chinese crew manipulated by "God" Collier waters in eastern Queensland Tai Kai Poer Island, 70 kilometers in the evening and ran aground. The Queensland government said in a statement, the preliminary investigation found that the vessel has a little oil, grease floating in the hull around the sea, and serious pollution of the Great Barrier Reef. The official organization gives to the conclusion, the reason to cause this accident is the crew to cut corners when crew fatigue induction, the pilot did not do a very good duty Outlook. The crew work schedule is all false, therefore, after the berthing of ships in Australia, the PSC specifically on the strict inspection by the Attorney and detained some of the ship, this time to the shipping industry a serious negative impact.
