Abstract
The scientific world has for a long time worked with linear tools to explain complex non‐linear phenomena. Also non‐linear relationships were transformed to linear in order to be handled. This was so despite the fact that nature has been giving us examples showing that the real world was complex, dynamic and non‐linear. This was so until developments in computer science provided the calculating means to the theory of complexity. Today, the theory of complexity is applied to many sciences and to disaster management as well. The application of complexity theory is attempted from a disaster management point of view. As the first attempt to incorporate management science into marine disaster prevention was the so‐called International Safety Management Code of the International Maritime Organization in 1998, we will attempt to connect the theory of complexity to the ISM code. The ISM code, being a safety standard, has been based on good management and organization rulesl. However, ISM code was accused of increasing the bureaucracy of the system with a result that no substance work could be done at the end. Moreover, a need has now emerged, i.e. to establish a “particular ISM code man” among the crewmen on board all ships. On the other hand, modern complexity management suggests more flat hierarchies where information travels faster, and this is something needed in a marine disaster.
