IDEA USD 185 PMT FOB USGULF 'WHERE IS AS IS'.
The Mobile Offshore Jack up was built in 1959 and functioned as a mobile
offshore drilling unit until conversion to a production facility in June
1984. Upon conversion, was towed to Ship Shoal Block 134 where it continued
to produce hydrocarbons until late 1999.
The Production System, at that time was an approximate capacity of 240
MMCFPD, 1300 BCPD, and 7560 BWPD.
She was classified by ABS as A1 Offshore Installation - Platform and
current ABS Annual Hull and Annual Load line Certificates have been
maintained.
The compressors and production equipment have been removed from the Vessel.
