HOUSTON -- Rolls-Royce this year will deliver eight RB211 industrial gas turbines for Total's Nigerian offshore oil and gas fields.
With the new deliveries, Total has ordered so far 19 for service offshore Nigeria as part of contracts worth $150 million.
Six of the RB211 gas turbine packages will be electrical generating sets, three for each field, to provide up to 160MW 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 recovery in the Usan field. The new Usan oil field, 100 kilometers (62 mi) southeast of Bonny Island in water depths ranging from 750 to 850 m (2,460 to 2,790 ft), is scheduled to become operational in 2012, when production will be in the region of 180,000 b/d.
Phase two of the Ofon oil field development will allow an increase in oil output from 25,000 b/d to around 100,000 in 2011. The gas produced from the field will be piped to the Amenam complex.
The packages for Usan and Ofon are due for delivery to the module fabrication yards by the fourth quarter of this year.
Rolls-Royce has now received orders for 34 RB211s to operate offshore West Africa: 26 from operators offshore Nigeria, and eight from operators offshore Angola.
The engines will be manufactured at the company's plant in Montreal, Quebec, Canada, and packaging of the electrical generating sets and gas compression units will take place at the company's Mount Vernon, Ohio facility.
