Blue is the colour as Man B&W engines head to UK
Blue-NG, the UK-based renewable power company, has ordered two MAN B&W 7K60MC-S engines to power two environmentally friendly power plants in London.
Each sister plant, located in the Southall and Beckton districts, will have one MAN B&W 7K60MC-S engine at its heart, manufactured by MAN Diesel’s Polish licensee H. Cegielski – Poznan S.A.
Each engine develops 13.9 MW at 150 rpm and is installed with an Organic Rankine Cycle (ORC) turbine and Turbo Compound System (TCS) for increased efficiency.
The heat produced from the two plants will be used in the gas pre-heating process, which is a necessary part of the pressure reduction process for liquid natural gas, and will supply renewable electricity, corresponding to the consumption of up to 100 000 homes.
Blue-NG signed a turnkey construction contract with Land & Marine Project Engineering Ltd. for the design and construction of the power plants in June 2009.
The engines represent the latest generation of the popular, two-stroke, low-speed MAN B&W K60MC-S engine and will run on crude rapeseed oil. In general, the development of this latest generation has targeted lower heat rates and lower CO2 emission.
Blue-NG is a UK-based renewable power company that builds and operates generating plants that produce electricity and heat locally.
The company is a joint venture between the National Grid, the UK’s gas and power-distribution company, and 2OC Ltd., a company well known in geothermal energy and natural gas pressure-reduction station projects, applying proven technology to generate carbon free electricity.
Land & Marine Project Engineering Ltd. is a Wirral-based, international engineering and contracting company with business activities in many segments, including commercial and industrial CHP (combined heat and power) plants and direct injection and co-fired biomass plants.
Tognum supplies gensets for Russian nuclear power plant
Tognum has won an order for emergency gensets to be installed in a Russian nuclear power plant.
In early 2012, the German company will supply MTU Onsite Energy emergency gensets to the value of around €26m ($36.4m) to Zvezda Energetika, a Russian specialist for energy solutions. The end user will be the state-owned power plant operator Energoatom Concern OJSC.
The gensets with MTU 20V 956 TB33 engines will be used for emergency power supply in a nuclear power plant near the city of Nowoworonesch in central Russia. The plant is currently under construction and is scheduled to connect with the grid in 2012.
“This order represents a breakthrough on the Russian market for emergency power in nuclear power plants”, said Christof von Branconi, member of the Tognum executive board and responsible for the business unit Onsite Energy & Components. Previously, only gensets from local manufacturers were used in Russian nuclear power plants.
Moreover, there are good prospects of follow-up orders as three new NPP projects will be launched in Russia in 2010; an additional 15 nuclear power plants are presently under construction or being planned.
The emergency gensets from MTU Onsite Energy generate a total of 36 MW – enough to power around 18 000 households. Within only 15 seconds, the gensets in the NPP run up to their nominal speed.
Different safety-relevant consumers are then connected in succession. After not more than 50 seconds, the gensets have accepted full load. With this order Tognum has prevailed against heavy competition. Apart from 50 years of experience in operating MTU products in the field of emergency power for nuclear power plants, the compact design was a decisive factor.
Novovoronezh I has been in service since 1964, making it one of Russia’s oldest nuclear power plants. Novovoronezh II is being built near the old facility and each reactor block will generate 1200 MW.
MWM ships 15 gas gensets to Bangladesh
Mannheim-based MWM has shipped no less than 15 gas gensets with an output of 4 MW each to Bangladesh.
The project, which is unprecedented in the company’s history, was started in spring of last year and is currently being installed at the destination. The buyer is a power plant of Precision Energy Ltd., a specially formed subsidiary of a leading group of companies in Bangladesh.
MWM, a tradition-rich company established by Carl Benz, is one of the world’s leading providers of decentralized energy generation plants.
The TCG 2016, 2020, and 2032 engines, which deliver an output of 300 to 4300 kW, are marketed in Asia by the company’s own subsidiary MWM Asia Pacific Ltd. in Singapore.
Among other things, this location advantage enables the company to ensure competent and quick service along with extensive, quick supply of spare parts in the entire Asia-Pacific region. With its 15 large gas gensets, the natural gas powered plant in Ashugong, Bangladesh, will generate a total of 60 MW, all of which will be fed into the public grid. Bangladesh is with its population of about 150m one of the most densely populated countries.
Meanwhile, the country’s daily demand for electricity has grown to 5200 MW, compared to no more than 4000 MW actually produced. Investments worth $15bn are needed by 2020 in order to prevent the power industry from becoming an impediment to the country’s development.
“The project also contributes to the promotion of the required investments for the maintenance and expansion of power production in Bangladesh”, explains Dr. Ruprecht Lattermann, President and CEO of MWM Asia Pacific. The realization of the order represents further proof of MWM’s growth strategy, which has resulted in the implementation of numerous projects in the application fields of natural gas, biogas, and diesel through an ambitious marketing approach in the past two years. Just recently, the company opened an office in Korea.
The 15 gas gensets, which have now arrived in Bangladesh, have covered a total distance of about 16 000 km (10 000 miles). About 40 low-bed trailers were needed for transporting this heavy equipment from the port in Chittagong to the destination.
The project was rolled out with Kaltimex Energy Pvt. Ltd. from Dhaka, Bangladesh, which has already successfully implemented numerous local projects with MWM and has established an efficient sales and customer service organization in recent years. According to the MWM headquarters in Mannheim, Germany, the commercial launch of the new power plant Ashugong is scheduled for the first half of 2010.
Wärtsilä wins four gas power plant orders from Turkey
Wärtsilä is to supply the equipment for four gas power plants under construction in Turkey.
The new gas power plants are scheduled to be operational in the spring and summer of 2010. Wärtsilä has also signed maintenance agreements for two of the installations.
Wärtsilä signed contracts to supply the equipment for an extension to the Rasa Enerji power plant in Van, in the east of Turkey, and for the Naksan power plant project in Gaziantep, located close to the Syrian border in the southeast of Turkey.
A third installation is for the Marmara Pamuklu power station in Corlu, close to Tekirdag, which is located in the northwest of Turkey. Most recently, Wärtsilä has been contracted to supply equipment for the H.G. Enerji power plant project in Gediz, in the province of Kütahya in the Aegean region of the country.
The Rasa Enerji extension order consists of three Wärtsilä 20V34SG gas-powered engines, as well as the compressed air, charge air and exhaust systems for the plant. This additional 25 MW will bring the total power plant output to 106 MW, to be fed to the national grid. The power plant is located at an altitude of approximately 1700 metres and, because of the altitude factor, a key prerequisite was that the engines should be capable of achieving maximum capacity with no de-rating. The Wärtsilä engines are fully able to meet this performance requirement.
The Naksan power plant project is being developed by Naksan Plastik San Ve Tic A/S, who will use the electricity and heat generated by the plant for its own packaging manufacturing processes. Any surplus electricity will be sold to the national grid. The contract calls for Wärtsilä to supply the engineering and equipment, consisting of two Wärtsilä 20V34SG engines running on gas, as well as the compressed air system, radiators and charge air filters. The combined out put will be approximately 18 MW.
The third Wärtsilä contract is for three Wärtsilä 20V34SG engines to be installed in an extension to the Marmara Pamuklu power station in Corlu, Turkey. The engines will be run on natural gas and will have a combined output of 25 MW. The contract has been awarded by Marmara Pamuklu Mensucat San ve Tic A/S, a textile and paper producer who will use heat from the power plant for its paper and combined cycle processing. The electricity generated will be sold to the national grid. Wärtsilä has previously supplied the generating equipment for the company’s original power plant, and this latest extension will now bring the total output of the plant to 78 MW including 6 MW from a steam turbine.
The latest project contract has been placed by H.G.Enerji Elektrik Üretimi Sanayi Ve Ticaret AS, a company specialising in textiles. The order consists of six Wärtsilä 20V34SG engines running on gas and producing a total output of 50 MW, plus all ancillary equipment with the exception of the boiler. The electricity generated will be sold to the national grid.
“Wärtsilä’s strength in the Turkish market is a clear indication of our good reputation in the country, our efficient service support operations, and of course, the quality of the Wärtsilä generating equipment. We are especially delighted to be delivering equipment to Gaziantep. It is one of the largest industrial parks in Turkey, and this will be an excellent reference installation,” says Christer Strandvall, Regional Director for Western Europe, Wärtsilä Power Plants.
