Dresser-Rand to power semi-submersible oil production platform
    Dresser-Rand has been awarded a contract by Petrobras Netherlands B.V.to supply power generation packages and equipment services for its planned P-55 semi-submersible production platform.
    The value of the contract is approximately USD100 million.
    The agreement includes a USD78 milion order for four power generation units employing Dresser-Rand's advanced, modular VECTRA 40G gas turbines, as well as a continuing service contract worth up to USD22 million.
    The VECTRA 40G reference turbine is ISO-rated 30.4MW output and 38.9% efficiency.
    P-55 will be a floating, deepwater oil platform with a production capacity of 180,000 bpd. Petrobras intedns to install the platform in a water depth of 1,795 meters at the Roncador field in the Campos Basin, located off Brazil's southern coast. The platform is scheduled to begin operations in early 2012.

Caldwell applies wet compression retrofits on GE Frame 7EA GTs

Caldwell applies wet compression retrofits on GE Frame 7EA GTs
    Caldwell Energy fo Louisville, KY has sucessfully completed the first application of its wet compression technology to GE's Frame 7EA gas turbine.
    Retrofit wet commpression systems were installed on four in-service GE Frame 7EA turbines at a utility power plant on the US east coast.
    Following the modifications,all foru engines were returened to operation. According to Caldwell, post-mod monitoring indicates that the retrofit has enabled the turbines to achieve a 10% increase in power output, as well as improved heat rate and a reduction in NOx emissions of nearly 50%
    Wet compression-also called water-spray evaporative turbine intercooling-introduces a controlled water spary at the turbine inlet in order to:
-Optimize the working fluid of the compressor to increase its efficiency.
-Increase the overall turbine mass flow.
-Allow constant firing temperature control systems to promote more complete combustion of fuel.
    Caldwell claims its technology can achieve output improvements of 8-15% for any type of gas turbine,with consistent performance across a wide range of ambient temperatures. In addition, wet compression systems can be used in conjunction with complementary cooling technologies such as  inlet chilling and fogging.
    Previously, Calwell has successfully demonstrated retrofit wet
compression systems on a variety OEM gas turbines.

Ontarino Power Authority greenlights 393MW York Energy Centre

Ontarino Power Authority greenlights 393MW York Energy Centre
Calgary-based Pristine Power Inc.announced that affiliate company York
Enerqy Centre LP has been awarded a 20-year contract from the Ontario Power Authority (OPA) to construct,own and operate a 393 MW natural gas-fired power plant located in the Township of King,Ontario.
    The York Enerqy Centre project will be jointly owned by Pristine Power Inc.and an affiliate of Harbert Power,LLC, a US project
developer based in Birmingham,AL.
    The Centre will be constructed at a cost of approximatedly CAD365 million, with commercial operations expected to begin by the end of 2011.
    Pristine Power submitted the York Energy Centre plan in response to an OPA request for proposals to develop approximately 350 MW of requird quick-response peak generating capacity for the Northern
York Region.
    As conceived, the new facility will incorporate state-of-the-art gas turbine technology and will be designed to meet current and evolving environmental standards.
    Ontario is actively developing gas-fired turbine generation project in order to reduce grid reliance on older, less-efficient coal-fired power stations.Pristine Power is already moving forward with the OPA awarded 84MW East Windsor Congeneration Centre,which is scheduled to go onstream in mid-2009.

Reliance accelerates development of giant 7480MW Dadri project 

Reliance Power has fast-tracked its plans to construct the massive Dadri power generating facility in Uttar Pradesh. The 7480MW project will be the largest single-site, gasfired power station in the world and will cost an estimated UD4-5 billion.
Reliance Power is a Mumbai-based company in the Reliance Anil Dhirubhai Ambani Group(ADAG), and is a major developer and operator of power generation projects both inside India and internationally.

    The decision to accelerate the project schedule followed the India government's guarantee of natural gas fuel supplies to the proposed project site, which encompasses more than 2,000 acres of ADAG-owned property. Prior to receiving the government's fuel assurances, Reliance had already secured most of the necessary approvals for the project, including environmental clearance and water linkages.
    Remaining hurdles largely relate to Reliance's application to the government to designate the Dadri comples a Special Economic Zone(SEZ). While the site has been granted tentative SEZ status form the Commerce Ministry's Board of Approval, final reviews are still pending.
    Reliance hopes the status issues can be resolved and project financing finalized by September, in order to remain on-track for a planned project start before 2011.
    Meanwhil, Reliance has initiated negotiations with General Electric,Bharat Heavy Electricals and several other power equipmnet manufacturers for the supply of turbines,boilers and generator for the project.
    Plans call for the Dadri facility to be builtin two phases. The first phase will generate 3600MW of electricity and will incorporate four to five gas turbines.

Consortium secures financing for 420MW Tessenderlo CCGT project

  

Consortium secures financing for 420MW Tessenderlo CCGT project
A development consortium consisting of International Power, Siemens Project Ventures and Tessenderlo Chemie has secured long term financing for the proposed T-Power 420MW CCGT greenfield generating project located at Tessenderlo,in eastern Belgium.
    Total cost of the project is estimated at EUR448 million. The three consortium partners will hold equal owenership shares, with Siemens acting as turnkey EPC contractor and International Power manging ongoing plant poerations under a 15-year ocntract.
    The combined cycle generating facility will be anchored by a Siemens SGT4000F gas turbine with ISO-rated output of 416MW at 58.2% efficiency in a 1x1 CCGT configuration.
    Current plans foresee commercial operations commencing in 2011,with the station's power output to be purchased by Essent Trading Interantional S.A. under a 15-year tolling agreement with a 5-year extension option.Under the terms of the agreement,Essent will supply natural gas fuel for the generating plant.

MHI ready to transition 320 MW J-Series GT from test-bed to market

MHI ready to transition 320 MW J-Series GT from test-bed to market
Mitsubishi Heavy Industries (MHI) has completed development of its J-Series gas turbine, Which delivers the highest output and thermal efficiency of any GT engine.
  The company plans to move quickly to begin marketing the new GT,with
first deliveries expected as early as 2011.
  The 60 Hz J-Series turbine has a rated power output of320 MW (ISO basis)in simple cycle operation.In addition, production versions of the J turbine has a rated power output of 320 MW (ISO basis) in simple cycle mode and 460 MW in combined cycle operation.In addition,production versions of the J turbine will enable thermal efficiencies in excess of 60% in combined cycle configurations.
  Mitsubishi's J-Series builds on the best elements of the company's G turbine technology, which has continued to evolve through successive modifications and materials and design improvements for over a decade.
  In addition, the J turbine benefits from both leading-edge computer enginerring capabilities and technology advances that have been achieved as a result of Japan's goverment-sponsored initiative to develop ultra-efficeient engines that operate at inlettemperature above 1,700 C
  With the adoption of low-thermal-conductivity TBC (thermal barrier conating) technology and improvements in cooling efficiency, the J-Series gas turbine is able to operate at inlet temperature approaching 1,600 C-100 degrees higher than the current-generation G units.
  In addition, enhanced three-dimensional design techniques have eanbled Mitsubishi to further improve turbine aerodynamics and increase compression ratio.
  According to Mitsubishi, increased out put and enhanced fuel efficiencies are only part of the story. As a result of its highly effieient combustion design- which retains the steam-cooling technology originally developed for Mitsubishi's G turbinges the
J enine also offers exceptional environmentl performance. Nox reduction form commercial J units is expected to equal the top of the line Gs, while Co2 emissons will be fully 50% less than a same-rated conventional coal-fired power plant.
