Fatigue. It’s a way of life for so many of us. From first responders to students to the transportation industry, it’s a badge of honor to pull the all-nighter or push through an extended period with no rest.
The military is another community for which fatigue is no stranger. U.S. Naval Special Warfare (NSWF) pushes their troops to the limit during initial training (Basic Underwater Demolition/Seal Training (BUD/S)) under very controlled circumstances, including stressors such as hypothermia and sleep deprivation.
But, at what cost?
Incidents within the past year involving U.S. naval vessels, including the fatal collisions of the USS Fitzgerald and USS John S. McCain, have highlighted fatigue and overwork as possible causal factors. The differences between fatigued crewmembers onboard these warships and soon-to-be SEALs in BUD/S are the controls in place. During BUD/S training, carefully prepared spreadsheets tell instructors just how far they can push their sailors. These controls allow the prospective SEALS to understand how their bodies and minds will react when fatigued, under stress and overworked, while keeping them safe. This is in stark contrast to the crew of warships that have no such controls in place.
“We’ve got to find a way to safely and proficiently test our people in higher fatigue conditions along the way,” he said. “And we have to teach them the difference between fatigue conditions and those routine conditions as well.” – Admiral Phil Davidson
If you walk onboard any merchant vessel in the world, you will easily have a discussion of rest hours, fatigue mitigation and, yes, issues getting adequate rest, with most any crewmember. Why is this? The STCW (Standards of Training, Certification and Watchstanding for Seafarer’s) Code from the IMO (International Maritime Organization) is the short answer. The longer answer will also include the Maritime Labor Convention (MLC) of 2006 from the International Labor Organization (ILO). The combination of these international conventions limits the work hours of the average mariner to 13 hours/day on average and has requirements for tracking of their rest hours.
The STCW and MLC 2006 rest hour regulations pose challenges for merchant mariners, yet provide targets towards which to aim. The U.S. Coast Guard has also looked at fatigue factors, including their Crew Endurance Management program – elements of which are linked below.
It is understandable why Admiral Phil Davidson, Commander U.S. Fleet Forces indicated to Military.com that sailors must come to terms with the fact that they will be asked to fight while exhausted. Warfare doesn’t take timeouts for adequate rest, after all. The problem arises when sailors and soldiers are required to work far beyond their physical and cognitive capabilities on a routine basis. It is at this point of diminished cognitive ability that their decision making becomes questionable. When these same sailors are put in control of aircraft, warships and other modes of transportation, tragedy can and will occur.
Training while fatigued is understandable so that the effects might be understood during times of peace. Routinely operating while fatigued is a potential waste of life – both for those who may pay the ultimate price and for those held responsible. The research has been done and the programs are in place with the U.S. Coast Guard and Merchant Marine. For the U.S. Navy, it might be as simple as adopting one or the other.
