Seahealth - a new guidance on fatique - Shipping and rest

Download publication as PDF

At the tale of survey on well-being: Seahealth has released a guidance entitled Shipping and Rest

Rest at sea is the subject of much attention. Do seafarers get enough sleep aboard? What are the consequences of lack of rest? And what is written in the law and how do we comply with them? These are issues that affect both health and safety for crew members on the ship. This guidance provides some answers and inspiration for planning work and resting time.

Horizon Research Project

Horizon Research Project is designed to examine how fatige at sea can cause commercial losses as well as risking the safety for the seafarers.

The project claims that fatigue and mental exhaustion inhibit the mate's ability to take action and make decisions.

The project examines how the organization of the timetables has a significance for the crews feeling of fatigue.

Horizon Research Project gives advice and guidances in how to improve the resting procedures on board.

The people behind the project have prepared some tools that agents in the maritime sector can use to avoid fatigue.

Horizon Research Project is a co-operation between Warsash Maritime Academy (Southhampton University), Chalmers Tekniska Hoegskola AB (Sweeden) and the Department of Stress-Research at Stockholm University.

Fatigue at Sea - Reports, articles and links

Fatigue at Sea by Capt. Margareta Lützhöft PhD, December 2007, is a Swedish study that demonstrates the interaction between the watch system, reaction time and health status. Margareta Lützhöft prepared the report for the Swedish VTI (Swedish National Road and Transport Research Institute) that focuses on the problem of fatigue at sea as a stress factor for individuals and which may also represent a risk for safety at sea. She held interviews and field studies at 13 Swedish ship-owners and with 30 experienced officers on 13 different merchant vessels of varying sizes and types. She made a special point of collecting and analyzing data on fatigue, stress and reaction time with respect to the widespread two and three watch systems.

IMO Fatigue Guidelines

At its 71st session (19 - 28 May 1999), the Maritime Safety Committee (MSC) considered the issue of human fatigue and the direction where IMO efforts should be focused. In this regard, it was agreed that practical guidance should be developed to provide appropriate information on fatigue to all parties concerned. This guidance should inform each party that has a direct impact on vessel safety (naval architects, owners/operators, masters, officers, ratings, training institutions, etc.) of the nature of fatigue, its causes, preventive measures and countermeasures.

Fatigue guidelines IMO (pdf)

The guidelines on fatigue contain practical information that can assist interested parties: owners, masters, officers, crew and instructors to better understand and manage fatigue. The guidelines provide information on the potential dangers of fatigue and ultimately the effect on the health and safety of the personnel working on ships.

Seafarer Fatigue - Project from Cardiff University

The project Seafarer fatigue is prepared by Andy Smith, Paul Allen and Emma Wadsworth from Cardiff University.

The project contains a report and a movie which state those factors that make seafarers particularly exposed to fatigue.

The people behind the project believe there is a lack of knowledge about fatigue at sea which they try to compensate for by this project.

In the report and in the movie they highlight how lack of sleep, poor working conditinos and high expectations at the workplace can create fatigue in the everydaylife of each individual.

As consequenses of fatigue the scientists mention everything from an increase in accidents to the risk of mental as well a physical overload for each individual.
