Entered shipyard on 1/24/2008 for 91 days to upgrade to NC-5SM mooring standard (inclusive of work to complete hurricane damage repairs). In consideration of the NC-5SM upgrade, the indicated contract dayrates resulted in an effective dayrate during the period of 8/08/2007 through 4/24/2008 of $329k-$331k, reduced to 95% of the operating dayrate for the first 60 days in the shipyard ($313k-$314k) and 80% of the operating dayrate for any days in the shipyard from 60 days ($263k-$265k) up to 85 days. Experienced 6 days at zero rate in 2Q 2008 related to the upgrade.
