As built, the ship was an ice-strengthened research vessel . The vessel measured 1,496 gross register tons (GRT) and 1,050 tons deadweight (DWT), was 65.1 metres (213 ft 7 in) long overall and 56.0 metres (183 ft 9 in) between perpendiculars with a beam of 13.1 metres (43 ft 0 in). In 1986, the ship was lengthened to 75.3 metres (247 ft 1 in) long overall and 67.4 metres (221 ft 2 in) between perpendiculars. The vessel was remeasured as 1,982 gross tonnage (GT) and 1,100 deadweight.
The ship is powered by two MaK 6M-453 diesel engines driving one shaft turning a controllable pitch propeller , one stern thruster and two bow thrusters rated at 4,500 horsepower (3,356 kW). The ship is capable of 14.5 knots (26.9 km/h; 16.7 mph) and has a cruising range of 17,000 nautical miles (31,000 km; 20,000 mi) at 12 knots (22 km/h; 14 mph).
In Brazilian naval service, the research ship has a standard displacement of 1,928 long tons (1,959 t) and 3,628 long tons (3,686 t) at full load. The ship is equipped with a helipad and is capable of operating up to two UH-13 Helibrás Esquilo helicopters.
