   Sammanfattning : Abstract  The permit application process for offshore wind farms (OWF) in Sweden conceivably requires a comprehensive and transparent complement within risk management. The NETEP framework (covering risks concerning navigation, economics, technology, environment and politics), based on a futures planning mechanism (STEEP) has consequently been brought forward as a structure for the application of FMECA (Failure Mode, Effects, and Criticality Analysis) methodology to the permit application process of the Swedish offshore wind farm sector.

3. 2. Dependability and safety evaluation of railway signalling systems based on field data

   Författare :Amparo Morant; Patrik Hilber; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance Engineering;

   Sammanfattning : Railway signalling systems can be considered a group of complex systems that together provide control, supervision and protection of railway operation. When a failure occurs in the railway signalling system, other safety mitigation measures are put into place to continue railway operation, e.g. LÄS MER

4. 3. Some problems on the selection of a condition based maintenance technique for mechanical systems

   Författare :Basim Al-Najjar; Bo Bergman; Linköpings univeristet; []
   Nyckelord :Terotechnology; Systemekonomi;

   Sammanfattning : In the first paper we focused mainly on establishing a sequential method for the selection of a maintenance technique for mechanical systems. The selection problem is studied for the components having considerable consequences and a non-negligible failure intensity. LÄS MER
