Proactima (phase 1)
• Develop method for evaluation• «One pager» evaluation for each measure
• Effect of the measure• given temperature, wind and precipitation
• Effect of the measure on energy consumption• given temperature, wind and precipitation
• Effect of the measure on cost• investment and operating cost
• Vulnerability of the measure• operational and organisational

Apply method (phase 2)
• Evaluation of all identified measures and solutions will be performed
• Qualitative evaluation by work group comprising experienced proffessionals
• «One pager» for all identified measures and solutions
• Document result of evaluations
• Report expected 3Q 2018
• Plan to publish report on PSA website 4Q 2018
Conclusion
• Work so far indicates that:
• a large variety of solutions and measures are available for each winterization issue
• there may be a challenge to find the optimal combination of solutions and measures for different conditions at specific locations
• It appears that identified measures and solutions, technical, operational and organizational, ensure safe and efficient operations in the Barents Sea

Results - Operational and organisational measures• Competence and training
• education and training in proper use of winter technology• defensive behaviour with respect to falling ice and slippery surfaces
• Stop work• Essential equipment out of order, slippery work areas or potential for falling ice and snow • work should only be performed when safe and normal working conditions are in place
• Power and heating• Ensure sufficient power and heat for winterization measures, e.g. heating, HVAC, process heat, etc.
• Inventories of consumables• Ensure sufficient inventories of consumer articles related to winterization and operation before each winter
season
• Checklists for inspections• before and during winter season, secure areas and equipment when temperature drops towards freezing• when low temperatures are expected, the platform management should go through planned measures for
inspection and action. Responsibility for various activities, areas and checklist should be clear.
