As planned, Ultrapetrol continues its newbuilding program in India that will add capacity to our Offshore fleet. We expect to take delivery of the first of the remaining two PSVs, UP Pearl, during the second quarter of 2013.
We entered into new four-year time charters with Petrobras for our UP Agua-Marinha, UP Diamante and UP Topazio at significantly higher rates than their expiring contracts while we extended the charter for UP Esmeralda for another four years. In addition, both UP Amber (on its way from India to Brazil) and UP Pearl have been contracted for four years to Petrobras. These new contracts and vessels are expected to produce substantial additional EBITDA.
The Company believes that the Brazilian market will grow in-line with Petrobras' aggressive capital expenditure plans. Ultrapetrol's fleet has the advantage of being very modern and technologically capable of supporting deep sea oil drilling in Brazil as well as the North Sea.
OceanThe Ocean Business segment generated adjusted EBITDA of $0.2 million in the first quarter of 2013 as compared to adjusted EBITDA of $0.1 million in the same period of 2012. For a reconciliation of segment adjusted EBITDA to operating profit (loss), please see the tables at the end of this release. The 7% decrease in revenues from $18.1 million to $16.9 million is mainly attributable to the transportation of the nineteen barges and one pushboat sold to a third party to Colombia during the first quarter of 2012; partially offset by a revenue increase from our Amadeo related to its drydock during the first quarter of 2012, to an increase in revenues from our Argentino, and to higher charter rates of our Product Tankers during the first quarter of 2013 when compared to the same period of 2012. The Company operated a total of four vessels in its Product Tanker fleet in the first quarter of 2013 ( Miranda I, Amadeo, Alejandrina, and Austral) which continue to be employed in the South American coastal trade on charters with major oil refineries that operate in the region. The volumes in our container feeder service, particularly in the southbound leg, have been sustained at high levels.
