The Brazilian petroleum industry continues to set new standard for fleet expansion. This is demonstrated by the building of 12 aluminum 7,200-hp fast supply vessels to a single order. They are being built at Estilaleiro ETP Engenharia Ltda. in Rio de Janeiro for two owners. Designed by Incat Crowther with their Lafayette, Louisiana office, the construction of these vessels is now well along with the first delivery expected for late 2013 with others to follow through 2014 and 2015.
The 12 boats under construction in Brazil will be 48 by 9.5 meters with a molded depth of 4.25 meters. They will have 225 square meters of deck space with a capacity of 250 tons. An additional 30-square-meter covered cargo area will accommodate up to 30 tons. Tanks for 44,600 liters of ship’s fuel with another 90,600 liters of cargo fuel are built into the hull. Water for onboard use will be carried in 9,000-liter tanks with additional tanks for 91,000 liters of cargo water tanks.
Four Cummins QSK50-M main engines, each producing 1,800 hp at 1,800 rpm, turning propellers, through Twin Disc MGX-6848SC gears with 2.93;1 reduction, will give each vessel a 25-knot top speed and a 21-knot service speed. The vessels will be fitted with a pair of Thrustmaster 30TT150ML 150-hp electric tunnel bow thrusters. A pair of Cummins QSM11 250kW at 1,800-rpm generators sets will provide electrical power.
Accommodations will be provided for up to eleven crewmembers in one single cabin and five double cabins. A small area aft of the interior cargo hold will include space for six passengers that can also serve as a conference room.
The 12 Fast Supply Vessels are being built to class +1A1 HSLC (bra) R1 Service 2 EO. Six of the vessels are being built for the Intertug subsidiary Baru Offshore Navegação while Senior Navegação will own the other six.
