2. 1. Offshore deployments of marine energy converters

   Author : Maria Angeliki Chatzigiannakou; Irina Temiz; Mats Leijon; Tony Lewis; Uppsala universitet; []
   Keywords : offshore deployments; risk assessment; wave energy converter installation; marine current energy converter installation; economic efficiency; time efficiency; offshore operations; point absorber; hydrodynamic analysis; slack sling criterion; hoisting system failure.;

   Abstract : The depletion warning of non-renewable resources, such as gas, coal and oil, and the imminent effects of climate change turned the attention to clean and fossil fuel-free generated electricity. University research groups worldwide are studying solar, wind, geothermal, biomass and ocean energy harvesting. READ MORE

4. 2. Broadening Horizons : The FMECA-NETEP model, offshore wind farms and the permit application process

   Author : John Ohlson; Bo Carlsson; Håkan Thorstensson; Linnéuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; cumulative impact; risk; offshore wind farm OWF ; FMECA; kumulativa effekter; risk; havsbaserad vindkraft; Miljövetenskap; Environmental Science;

   Abstract : 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.

5. 3. Reliability-based assessment procedures for existing concrete structures

   Author : Joakim Jeppsson; Avdelningen för Konstruktionsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete; reliability theory; service life; assessment; monitoring; hydraulic engineering; Civil engineering; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

   Abstract : A feasibility study of reliability theory as a tool for the assessment of present safety and residual service life of damaged concrete structures has been performed in order to find a transparent methodology for the assessment procedure. It is concluded that the current guidelines are open to interpretation and that the variation in the results obtained regarding the structural safety is too great to be acceptable. READ MORE

6. 4. A study of maintenance performance indicators for the Swedish railroad system

   Author : Thomas Åhrén; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

   Abstract : The Swedish railway authorities have a long tradition of using performance indicators to follow up their performance. Already in 1915 when they decided to electrify the iron ore line between Kiruna and Riksgränsen, they introduced some indicators to measure and follow up expected benefits of upgrading the transportation system, e.g. READ MORE

7. 5. Designing for Extremes

   Author : Olga Bannova; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; Architect; Human Factors; Engineering; Engineer; Multidisciplinary and Trans-disciplinary Design and Planning.; Extreme environments; Architecture; Design Planning;

   Abstract : The starting point of this research is based on personal experience in research and design for extreme environments, including orbital and lunar planetary facilities, disaster shelters, polar stations and offshore surface and submersible habitats. This work reflects on related to research problem technical papers, discussions with professionals about their work experience with projects in extreme conditions, and students' workshops debating strategies to form sustainable behavior and design practices.
