Rolls-Royce will deliver a further eight RB211 industrial gas turbines for Nigeria’s offshore oil and gas fields this year as part of contracts worth $150 million from TOTAL.
These units, for a Floating Production, Storage and Offloading (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 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 oil recovery in the Usan field.
The new Usan oil field, 100 kilometres southeast of Bonny Island in water depths ranging from 750 to 850 metres, 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 for Usan and Ofon are due for delivery to the module fabrication yards by the fourth quarter of 2009.


Filter company, Jenbacher distributor in Byelorussia, commissioned gas engine power plant for Euroopt trading center under the turnkey contract.
The power plant consists of two JMS 312 GS-N.LC power units (manufactured by GE Energy Jenbacher gas engines) generating 526 kW of electric and 640 kW of thermal power. The fuel is natural gas. BROAD absorption chillers generate cold for climate control.
Trigeneration operation of the power plant provides trading centre with uninterrupted supply of electricity, heat and cold. The second stage on the base of 1063 kW JMS 320 GS power unit is scheduled for the end of the year.


The customer for the project is Tomskneft-VNK JSC. Under government regulations dated 08.01.2009 oil producing companies are to increase casing-head gas utilization. Three P800 P1 diesel generators rated at 640 kW each manufactured by FG Wilson (Engineering) Ltd. have already been turned to dual-fuel operation on diesel fuel and diesel gas. Taking into account electrical load of the power plant, about 30-50% of primary fuel is being replaced.
A.D.D. Service specialists have already carried out similar work at Zapadno-Krapivinskoye field and others. In the project they use the equipment by ComAp Systems, Czech Republic. Payback period is 10-14 months depending on the capacity of the power equipment.


The power plant supplies gold and silver mine in Chukotka Autonomous Area with heat and electric power. The project is realized by Bema Gold Corporation, Canadian gold-mining company. The power plant is designed on the base of four Wartsila 32 diesel generating sets equipped with 12V32 engines with the capacity of 5.3 MW each. The power units operate on special diesel fuel avoiding congelation at severe winter temperatures. Taking into consideration severe climate at the site the latest Wartsila developments were used in designing of the power units.


Caterpillar Inc. announces the introduction of the C175-16 diesel package generator set for standby, prime and continuous applications. The generator set is available worldwide in 60 Hz packages with ratings up to 3.1 MW and 50 Hz packages with ratings up to 3.1 MVA. The Cat® C175-16 generator set package was designed to offer a larger unit rating, higher power density, lower emissions and reduced installation costs. Meeting U.S. EPA Tier 2 requirements, the new generator set addresses current and future needs of the worldwide electric power industry.
Unveiled in 2006, C175 diesel generator sets have successfully completed rigorous field reliability demonstrations in real-world applications spanning the globe.
The C175 has been used for applications ranging from distributed generation to prime power for remote communities, industrial processing plants and rock crushing applications.
Five key engine systems comprise the Cat C175-16: fuel system, electronics and controls, air system, cooling system and lubrication system. Engineers incorporated significant input from Voice of Customer (VOC) market research into the design of the systems, allowing Caterpillar to deliver a world-class engine to customers seeking standby and prime power application solutions.
The C175-16's fuel system utilizes a high pressure fuel pump and control valve that deliver multiple precise injections within a single combustion event. This results in lower emissions, improved performance and reduced fuel consumption. Driven by the ADEM™ A4 controller, the C175-16 engine management system provides superior performance, even in the most demanding environments.
The air system delivers cooler combustion air at the cross-flow cylinder heads, allowing for higher power density and emission reduction. A new generation of turbochargers was designed for the C175, providing a 5 percent efficiency boost and longer life when compared to traditional turbochargers.
A newly designed cooling system cools only the parts of the engine that require cooling, resulting in increased efficiency and lower heat rejection. This method of temperature control allows customers to reduce overall operating costs by using smaller radiators.
The lubrication system utilizes Cat® Advanced High Efficiency Oil Filters which provide a higher level of filtration efficiency while maintaining Caterpillar's superior capacity.


Siemens Energy is to adapt its proprietary process for carbon dioxide capture to the special conditions prevalent in and mode of operation of combined-cycle power plants for the Norwegian utility Statkraft. The project kicked off in January 2009 and is scheduled to be completed within two years. This technology will then be available for industrial-scale applications.
Fossil energy will remain the cornerstone of power generation for the foreseeable future. The task to be performed here is to meet increasing energy demand while simultaneously protecting our environment.
Combined cycle power plants are in great demand throughout the world due to their high efficiency and low environmental impact. They do, however, impose stringent requirements on the process used for CO2 capture. Their flue gas has a lower CO2 concentration than that in coal-fired plants while simultaneously exhibiting a high oxygen content, conditions which have a very negative impact on known solvents.
The technology for CO2 capture from the flue gas of power plants is an important feature of the Siemens environmental portfolio. In 2008, revenue from the products and solutions of Siemens environmental portfolio was nearly EUR 19 billion, which is equivalent to around a quarter of Siemens total revenue.


Mitsubishi Heavy Industries, Ltd. (MHI) has completed development of the "J-series" gas turbine, featuring the world's largest power generation capacity and highest thermal efficiency. The unit is designed to operate at a very high temperature near 1,600 degrees Celsius (°C) at the turbine inlet. The company has also launched activities towards the turbine's commercial production.
The 60 hertz J-series gas turbine achieves a rated power output of about 320 megawatts (MW) (ISO basis) and 460 MW combined-cycle power generation – also the world's largest. In gas turbine combined-cycle (GTCC) applications, high-temperature exhaust gas from the gas turbine is used to generate power by a steam turbine. The company is aiming to achieve over 60% thermal efficiency in GTCC applications, the world's highest level. The company will soon begin marketing, with delivery to commence in 2011.
J-series GTCC power generation will achieve CO2 emissions approximately 50% lower than with conventional coal-fired power generation (comparison with MHI's power plants). In this way, the newly developed turbine is expected to contribute significantly to worldwide efforts to reduce global warming.
