A World of Solutions
The Shaw Group
While the debate continues on climate change and effects of global warming,
many countries and organisations are demanding change and aggressively
pursuing new ways to combat the world’s energy crisis. As regulations evolve and
industries and governments take part in new and existing initiatives, one company,
The Shaw Group Inc. (Shaw), shows how it provides solutions in the three areas of
renewable and clean energy, emissions reduction, and environmental restoration.
Energy
Shaw provides engineering, design, and construction of new power generation
facilities, as well as refurbishment and modification of existing coal, gas, and
nuclear power plants using its Stone & Webster technology.
As part of an engineering, procurement, and construction (EPC) contract, Shaw
is building a new solid fuel-fired power plant using state-of-the-art circulating
fluidised bed technology. The new clean-energy technology uses petcoke, coal,
and other fuels in place of natural gas to generate power. This project will be
among the cleanest solid-fuel units of its kind in the United States (US).
The need to find alternatives to fossil fuels has been the driving force for
decades in the renewable energy market. Shaw has experience in geothermal and
hydroelectric facilities world-wide as well as engineering evaluations and design
studies for wind and solar power projects. In another EPC contract Shaw will be
executing a new 60 megawatt geothermal power plant project in Indonesia and is
leading a consortium for the engineering and design of the Konaktepe Dam and
Hydroelectric Power Plant in Turkey.
Shaw has provided quality-driven, innovative, and cost-effective services in
nuclear power development to more than 100 nuclear power plants worldwide
including 95% of the operating plants in the US. One project underway today
includes construction and construction management for the restart of Browns
Ferry Unit 1 for the Tennessee Valley Authority.
Emissions

Shaw is a leader in innovative design and construction of flue gas desulfurisation (FGD) systems like this one at
the Navajo Generating Station in Arizona |
Existing facilities can be modified with numerous emission control services
such as low NOX burner conversions, overfire air additions and clean system
conversions, selective catalytic reduction (SCR) additions, SOX, flue gas
desulfurisation (FGD), and scrubber additions.
Shaw performed the retrofit of limestone scrubbers and equipment to the threeunit,
2460-megawatt Navajo Generating Station in Arizona, one of the world’s
largest FGD projects. The scrubbers remove SO2 from the gases emitted through
the plant’s three chimneys.
Shaw operates technology development and research laboratories where
specialised emission testing methods are developed, evaluated, and verified
to meet air permitting and compliance requirements for all types of facilities
and government and private-sector clients. Services include: strategic and risk
management planning, air emission inventories, installation and operating air
permits, air pollution control technology, air dispersion modelling, and emissions
testing.
Shaw also is assisting clients with understanding greenhouse gas (GHG) emissions
at solid waste landfills - an important source of methane reduction that can be
used to offset carbon dioxide emissions. As GHG trading develops, Shaw is helping
clients with reviewing credit issues and verification along with facilitating credit
sales. Shaw has also installed landfill gas collection and control systems and
landfill gas-to-energy systems.
Environmental Services
Organisations taking a greater part in corporate responsibility and environmental
health and safety issues have to be strategic and this necessitates environmental
management systems, activity-based cost accounting, and corporate responsibility
programmes. Shaw’s strategic environmental management programme includes
environmental management systems (EMS/ISO 14001), pollution prevention (P2),
environmental cost accounting and sustainable development.
Another significant environmental issue has been the rise in hurricane activity
and as a result coastal flooding and erosion. The US Gulf Coast region has been
losing as much as 34 square miles of land every year for the past 50 years. Shaw
has been providing innovative project development, design engineering, and
construction management of extensive and complex coastal restoration projects
for more than 20 years.
