With EDG's extensive experience, whether it be Cogeneration, Combined Cycle, Waste Heat Recovery using Gas, Oil or other Fossil Fuel Steam Systems, EDG has the answer.
Introduction
EDG is a unique company offering a vast array of
specially services to the Power Generation Industry. Whether partnering
with independent power producers or working directly with the primary
client, EDG is a company set apart from the others. EDG brings that
rare ingredient of versatility to the table when proposing a method
or service to meet the requirements of any project. Quick to respond
with the experience required to do the job,
EDG is able to offer, in addition to individual specialities (detailed
under Electrical
Services )
complete turnkey systems, standard power package design, "balance
of plant" capabilities to mention a few.
EDG realizes the critical nature of the fast pace potential of many of the power projects and has been able to establish a world-renowned reputation of being able to commence difficult undertakings on a fast track basis and complete the projects in record time.
Primary
Generation
The possibility of an electric power failure has inevitably rendered
an opportunity for EDG to emphasize its reliability in responding
quickly to crises. One such project was performed for the Guam Power
Authority whose tiny island had suffered from major power losses
for years. In one year alone a substantial and vital portion of
the electrical power system had been destroyed due to three typhoons.
A primary electrical substation and transmission distribution gear
were on order when EDG was chosen to engineer, design, and construct
two 22 Megawatt turbine generator
power plants for the Yigo (pictured right) and Macheche areas. Utilizing
the Stewart & Stevenson's prime mover packages, the General
Electric LM2500 Turbine Generators, EDG commenced this difficult
undertaking and completed the project in record time.
As a reputed leader in generation station engineering, as well
as procurement, construction management, and installation supervision,
EDG served as prime
contractor on the $12 Million Standby Power Generation System for
the U.S. Navy Trident Submarine Base in Kings Bay, Georgia (pictured
left). Providing emergency back-up power to these facilities, EDG
installed nine identical 25OOKW diesel power generating units whose
secondary functions are now used for peak load shaving. The electric
power generation is integrated into a Station Generation Master
Control (SGMC) system designed and implemented by EDG. Each generator
unit was designed to operate individually, in parallel with each
other, or in parallel with the electric utility, Georgia Power.
Cogeneration
EDG's evaluation of alternative fuel supplies to reduce capital, operation and maintenance costs and maximize return on investment, is evidenced by EDG Cogeneration project experience EDG considers cogeneration as one of the most cost-effective and viable options to produce energy and simultaneously maximize usage of natural resources. One such installation performed by EDG, as the engineer and contractor, was the turnkey engineering, design, and construction of a 4.4MW Cogeneration Plant located in Ventura, California for UNOCAL North American Oil & Gas Division (shown right). This unit is used to provide 48MBTU/hour of heat necessary for the plant's oil and gas treatment processes as well as primary electrical power supply for the entire plant operation.
EDG
was awarded a design and installation contract by Agrico Chemical
Company to remove and replace their existing air compressor and
drivers at their Fertilizer Plant on the Verdigris River in Oklahoma.
The purpose of this cogeneration facility is to furnish steam and
compressed nitrogen for the Plant. EDG engineered a Sulzer (14,500hp)
centrifugal compressor and a GE Frame 3 turbine-driven compressor
with a Zurn Industries waste heat boiler. The compressor was installed
on a critical time path with installation and startup being accomplished
on target. As a result of this steam production, Agrico was able
to shut down one fired boiler and idle back another. The annual
savings were over $3 million.
In addition to land-based engineering capabilities, EDG possesses specialized experience in the designing of power generation modules for offshore platforms located in remote areas of the world. EDG was chosen to be the prime contractor for the design, procurement, fabrication, commissioning, load out and tie down of the complete turbine generator and power control module on a turnkey basis for the Takula Field, Offshore Cabinda, Angola, West Africa. The function of this platform (shown right) is for the exploitation of the oil and gas reserves in 180 feet of water located thirty miles offshore producing 80,000 BPD and generating approximately 5MW of power.
Contributing to EDG's continued success in performing this type
of sophisticated engineering endeavour is our unique expertise in
meeting the rigid requirements of space and weight constraints.
This three level module, 75 ft x 60 ft. x 56 ft, weighs just under
400 tons. The lower level houses 2 Solar-Centaurs producing 2.4MW
each and also the Power Control Building and waste heat recovery
system for crude oil heating. The integral Power Control Building
houses the motor control centres, switchgear, and offices. The top
level houses the emergency generator and battery room building,
fuel gas filter skids, deioniser package, diesel recirculation,
pumps, air start systems and a communications building. Above the
top deck is a heliport with safety net.
On
Lake Maracaibo, Venezuela, EDG supplied the design philosophies
and detailed engineering of the structural, electrical, instrumentation,
fire/gas detection, and SCADA systems for the Lagoven West Urdancta
Gas Compression Plant for Dresser Industries, Energy Systems Division.
The overall Lagoven complex is comprised of a control platform,
four compressor platforms, and two utility platforms. Each compressor
platform carries a 30,000 BHP Rolls Royce Turbine, driving a Dresser
Clark three-stage compressor train. Under normal operating conditions,
the combined gas turbine-driven compression modules were designed
to compress 200 million standard cubic feet of natural gas per day
from 30 PSIG to 1810 PSIG.
