Perenco Peru limited - Oil Barges and pushers
General Following Bureau Veritas studies and Navigability study it appears the optimum barge for hydrocarbon product transportation on rivers Napo and Curaray would have approximately the following characteristics: ∙ Length: 65 m ∙ Width: 15 m ∙ Double hull according to Bureau Veritas construction rules Depending on the season the maximum operational draft would be in a range of 1.2m (4 feet) to 1.8m (6 feet). In order to confirm tonnages of such barge some shipyards have been consulted to obtain corresponding designs. The most interesting design is presented here hereafter where for a usable volume of approximately 1500 m3 the light weight of the barge is 420t. Typical barge - Overall Dimensions: Length: 65m Breadth: 15m Depth: 2.65m Mass: 420t Mid Draught: 1.5m Capacity: Length: 60m Breadth: 13.4m Height: 1.85mVolume: 1490m3 or 9400bbl Assuming that densities for following products are: Gas Oil: 0.84 Naphtha: 0.74 Crude: 0.95 We obtain the following capacities forthe usable water depths:
Water depth (ft -m) 4’ – 1.2m 5’ – 1.5m 6’ – 1.8m 7’ – 2.1m Gas Oil (bbl) 5000 6900 8900 9400 Naphtha (bbl) 5700 7900 94009400 Crude (bbl) 4450 6060 7860 9400
*Note that this barge full of crude will have a 2.00 m draught. – Two models of pushers will be developed onecapable of pushing three barges and a second one for a single barge full loaded in the Amazon river.
