On 24 January, the IMO issued updated guidelines on fatigue. This is just another in a long series of band aids that attempt to cover over the problem without providing a solution. Fatigue is a long-standing weakness in the maritime industry. It is recognized as a major or contributing causal factor in the majority of maritime casualties. As is well-known, fatigue is caused by a lack of sleep and relaxation. These, in turn, are the result of too few people being tasked with too much work. Guidance on how to recognize and manage fatigue is meaningless.
