TDI-Halter, a Halter Marine Group, Inc. company, Gulfport, Miss., delivered Prisa 103, the last of the trio of newly-built drilling barges to Sedco Forex, the drilling division of Schlumberger Limited.
Measuring 180 x 75 x 15 ft. (54.8 x 22.8 x 4.5 m), Prisa 101, 102 and 103 are part of an overall conceptual design approach - an approach in which Sedco Forex
has permanently integrated the Well intervention structure, equipment
and systems to facilitate conventional light drilling and well re-entry with coiled tubing and other well intervention operations.
Joining the first two member of the trio, Prisa 103, which began the tow to Venezuela this past March, is currently deployed in the country's Lake Maracaibo for a 10-year contract with PDVSA.
