This vessel was chartered to Petroleo Brasileiro SA.The ship is built under the survey of DNV and designed in accordance with IACS common structure rule (CSR). The vessel has six pairs of cargo oil tanks, two slop tanks, fore and aft peak tanks, segregated water ballast tanks, fuel oil tanks and fresh water tanks. Cargo tanks are divided by plane type transverse and longitudinal bulkhead. Engine room and living quarters, and the navigation bridge are located aft.The ship was been designed as IMO DP Class 2 shuttle tanker, and is out Þ tted with a single slow speed diesel engine, one controllable pitch propeller, two bow and one stern thrusters, one bow and one stern retractable azimuth thrust-er and a bow loading system suitable for tandem loading operation in the Brazil-ian Waters-Campos Basin. It has a ß ush deck with forecastle deck for arrange-ment of the bow loading system. And the full spade rudder with ß ap system has been installed for good maneuverability. The main engine of MAN 6S70ME-C8.2 Tier II is derated to 15,200 kW of MCR at 82rpm for fuel economy and ß exible operation at part load. The speed of the vessel at draft of 16m is 14.8 knots at 90% MCR (13,680 kW) with 15% sea margin. The cargo pumping system allows a maximum unloading rate of cargo oil 12,000 cu. m./hr. with three cargo oil pumps. The maximum cargo loading rate is 17,000 cu. m./hr. through mid- ship cargo manifold or a cargo loading rate of 9,000 cu. m./hr. through the bow loading station. The vessel is equipped with Bow/Stern tunnel thruster having a power of 2,200 kW and azimuth thruster having a power of 2,500 kW with single speed motor for using dynamic position-ing and auxiliary propulsion.Length, o.a. ...........................................278.5m Length, b.p. ..............................................264m Beam .........................................................48m Depth ......................................................23.1m Draft .....................................................17.15m Deadweight Tonnage .......................155,710 ton Displacement ..................................183,367 ton Gross Tonnage ..................................83,078 ton Speed ...............................................14.8 knots Cargo oil ....................................167,500 cu. m.
