Project Status o o o o o RPSEA Project 08121-2301-03 was the highest rated project in the entire RPSEA portfolio at time of award RPSEA Project 08121-2301-03 and 09121-3500-07 are the lowest rated projects in the entire RPSEA portfolio in terms of Cost Share participation (11.2%) after 6 rounds of solicitation DTC s initial proposal was selected from 7 proposals submitted because it was the only proposal that offered a forward looking solution, i.e. 20 ksi, 350 deg F, 12,000 water depth vs. 10 ksi, 250 deg F, 6,000 water depth. DTC s second proposal was selected because it enhanced and completed the system being developed under the initial contract Project has essentially been on hold since last summer due to insufficient funding to support the negative cash flow 8 o The lack of industry participation and support has made it extremely difficult for DTC to complete this work and may result in these two projects being cancelled and funds being re-allocated to other projects o All work must be completed by 30 June 2014
