Stone & Webster

From Wikipedia, the free encyclopedia

Stone & Webster was founded as an electrical testing lab and consulting firm by electrical engineers Charles Stone and Edwin Webster in 1889. Stone & Webster was acquired by The Shaw Group in 2000. The company provides engineering, construction, environmental services, and plant operation and maintenance. The company has long been involved power generation projects and has worked on most American nuclear power plants. In the early 20th century, Stone & Webster was also known for operating streetcar systems in many cities across the United States; examples include Dallas, Houston and Seattle.

Stone & Webster was involved in creating the facilities and laboratories for the Manhattan Project. Prior to its acquisition it was also part of the Maine Yankee decommissioning project.

[edit] Service sectors

Nuclear

When Shaw acquired assets of Stone & Webster, Inc. a world leader in providing engineering, procurement, construction, maintenance support, and consulting services, we gained a rich legacy of expertise in the nuclear industry.

We have provided services to 95 percent of all U.S. nuclear plants and are providing services on the only two active restarts in North America.

Experience and Depth Premier nuclear maintenance contractor in the U.S. Original architect/engineer for 17 nuclear power stations Nuclear leadership: Manhattan project – Y-12 facility First commercial pressurized water reactor (PWR) – Shippingport First Nuclear Regulatory Commission (NRC) approved Nuclear Quality Assurance Program First-of-a-kind enrichment facility First license application – private fuel storage Providing services to over 40 operating plants Industry leader in nuclear uprates/upgrades Nearly 1,000 employees with nuclear experience Capabilities Engineering New plant design and construction Advanced nuclear plants Configuration management Controls modernization Decontamination and decommissioning Licensing support and safety analysis Operating plant services Maintenance and modification services Modification engineering/design Plant restarts Plant upgrades and uprates Quality assurance Radiological and safety analysis Spent fuel dry storage design

Fossil Power

With a century-old history of electric generation capability, Shaw Stone & Webster's fossil experience includes combined cycle, cogeneration, and coal-, oil-, and gas-fueled thermal plants in both brownfield and greenfield settings. Our services include NOx and SOx control and rehabilitation. Shaw's broad experience, global presence, and ability to facilitate project financing and risk management leverage next-century solutions for utility and non-utility clients.

We help developers succeed in building efficient, cost-effective facilities that meet their pro formas, and support utility efforts in divestiture, acquisition, and competitive enhancement of existing facilities.

Capabilities Thermal Plants

Coal-, oil-, gas-fired NOx and SOx emissions control Rehabilitation Combustion Turbines

Simple and combined cycle Cogeneration Repowering

Geothermal

Shaw, Stone & Webster is a leader in innovative design of new geothermal facilities and has provided complete assessments, evaluations, and recommendations for existing plant rehabilitation and refurbishment.

We have performed optimization and upgrade studies for more than 50 geothermal power plants around the world, representing more than 40 percent of worldwide geothermal capacity.

We have pioneered:

Geothermal power plant cycles that have significantly improved efficiencies Pollution control techniques that have moderated impact Ways to extend the life of existing facilities and optimize resource utilization and power production Capabilities Economic and technical feasibility studies Licensing and permitting support Environmental studies and mitigation Engineering and design Materials evaluation and selection Construction Plant startup and testing Operator training Operating plant support

Hydroelectric

Shaw, Stone & Webster provides total water resource development capabilities, ranging from site assessment and feasibility studies to complete project services.

We have helped many customers upgrade and rehabilitate equipment and facilities; provided support for FERC relicensing efforts; and evaluate expansions. Because of our extensive experience in all areas of the power industry—fossil, nuclear, geothermal, and hydro—we provide an objective resource in evaluating how existing hydro facilities would fit into a power producer's portfolio.

Capabilities Engineering and design Site appraisal Power planning Economic and technical feasibility studies Licensing and permitting support Reservoir operation studies Conventional and pumped-storage projects Plant startup and operations support Plant upgrading, rehabilitation, and expansion Safety assessments Operator testing Alkali aggregate reactivity studies and solutions

Renewables Biomass Processes Biomass used in currently operating power plants includes wood stock, wood residues, agricultural, and food processing. Shaw has engineered many biomass processes with state-of-the-art technologies using renewable fuel sources and has participated in numerous management programs for wood wastes, municipal solid wastes, tires, coal mining wastes, and municipal sewage sludges, primarily in the following categories:

Mass burn waste-to-energy Refuse-derived fuel (RDF) processing plants Composting Sewage sludge processing Wood waste-to-energy Biomass conversion Tire combustion Landfill Gas (LFG) Shaw provides landfill gas-to-energy (LFGTE) engineering, design, and operation services. In addition to building efficient LFG wellfield collection systems and operating the system optimally for producing energy, we provide complete recovery system turnkey design-build services and also operate our own and third-party LFG recovery systems.

Shaw manufactures and installs a proprietary gas-to-energy system that incorporates fuel recovery, fuel conditioning, and power generation in a single unit. Shaw provides equipment delivery, installation, engineering/permitting and operations for microturbine power systems, which are compact, low emission power generators that produce electricity from biogas and other fuels.

Energy Recovery

In addition to our power and process services, Shaw Stone & Webster offers a completely integrated set of energy recovery services for clients seeking a commercial use for their landfil and biogas.

Shaw is committed to continuing the development of those technologies and waste management programs that effectively address the current issues of residential, commercial, and industrial waste disposal.
