13 P&I for the configuration B 24/11/2010Thermosiphon project13

14 Configurations: advantages and disadvantages 24/11/2010Thermosiphon project14 Configuration AConfiguration BComments Not impact on operation for preventive maintenance Higher risk of impact on operation of preventive maintenance Mitigation : use of the brine circuit. Circuit redundancy Not impact on operation for single failures Mechanical redundancy Impact on operation for failures in no-duplicated components. Impact on operation in case of degradation of the circuit. Mitigation : use of the HAUG station. Power requirements: Standard power 160 kW Diesel power 75 kW Power requirements: Standard power 205 kW Diesel power 50 kW Depends on electrical services in Point 1. Balanced operation of compressors.Unbalance operation of the compressors. Mitigation : schedule for running the emergency chiller units. Easier operation and control logic ?More complicated operation and control logic ? This is not for sure Less spare parts required ?More spare parts required ? The thermosiphon works with BOTH solutions The HAUG station will be a back-up Difference in costs is unknown The thermosiphon works with BOTH solutions The HAUG station will be a back-up Difference in costs is unknown

22 PURCHASE DOCUMENTS Adjudication formula explanation, options and chosen solution. Risk matrix 24/11/2010Thermosiphon project22

23 Adjudication: options Adjudication on one option The adjudication is done comparing the price of one of the options. Risk: the company has no incentive whatsoever to put a low price in the options. Adjudication on the cheapest option for each supplier The adjudication is done comparing the cheapest option for each supplier. Risk: the technical option that will be purchased is not decided by us but by the cheapest of all the offers. Adjudication on the global price The adjudication is done on the global price for all the options Risk: the chosen company could not be the cheapest for the technical option required. 19/11/2010Thermosiphon project23
