Rolls-Royce Success in Nigeria
Rolls-Royce said it will deliver a further eight RB211 industrial gas turbines for Nigeria’s offshore oil and gas fields this year as part of contracts worth US$150 million from TOTAL. The units, for a FPSO vessel in the Usan field and a fixed offshore platform in the Ofon field, bring the total number of RB211s ordered by TOTAL for offshore Nigeria to 19. Six of the RB211 gas turbine packages will be electrical generating sets, three for each field, to provide up to 160 MW of electrical power for the new installations. All of the packages will also feature exhaust mounted waste heat recovery units. The remaining two sets will be gas compression packages to export gas to another facility or to re-inject gas into the oil field to enhance oil recovery in the Usan field.
The Usan oil field, 100 km southeast of Bonny Island in water depths ranging from 750 to 850 m, is scheduled to become operational in 2012, when production will be in the region of 180 000 barrels of oil per day. Phase two of the Ofon oil field development will allow an increase in oil output from 25 000 barrels per day to around 100 000 in 2011. The gas produced from the Ofon field will be piped to the Amenam complex. The packages are due for delivery to the module fabrication yards by the fourth quarter of 2009.
