Motivation

Short maintenance windows lead to enormoustime pressure

A variety of information is required to carry out the complex tasks and their documentation

Current information flows are characterized by a number of media discontinuities

The work is carried out under harshenvironmental conditions

The staff is well trained, but must be able to reactflexibly to situations that arise
