Offshore, Marine & ABS FORGING ADVISEMENT ABS CERTIFIED FACILITY Forging For Offshore & Maritime Classification Society Requirements At Scot Forge, we understand that working in the marine and offshore industries often comes with complex rules and regulations, which is why we created the Scot Forge Classification Society (CS) Advisors Group. This group is well-versed in oil, gas and chemical projects and products for marine applications, such as military or government projects, that regularly fall within a Classification Society's requirements. Our highly trained group understands the certification process required to manufacture or construct components for the maritime industry. We are an approved forging supplier, including heat treat and testing processes, for ABS , DNV-GL and Lloyd's Register . When you add the assistance of the Scot Forge CS Advisors to your project, you receive: Design Review – ensuring streamlined manufacturing that meets the Rules of the Classification Societies Supply Chain Optimization – minimizing costs and production delays Third-Party Witness Guidance – eliminating the risk of missed procedure certificates QUALITY ASSURANCE CUSTOMER COMMITMENT Add a Classification Society Consultation If You: Are new to Classification Society requirements Need a trusted partner to deliver your marine parts on time Want to ensure Classification Society compliance WHY DO I NEED A CS ADVISOR? Navigating the seas of maritime rules and required grades can be difficult, especially if your company is new to this market. The governing Classification Society Certifications will mandate that your component meet defined Rules for an application. For example, ABS Steel Vessel Rules part 2-3-7/1 Grade 2; MOU formerly MODU (mobile offshore drilling unit) Rules; DNVGL-OS-B101 Rules for Forgings; Lloyd's Rules for the Manufacture, Testing and Certification of Materials. In addition to knowing the general Rules and Grades for production, knowing the end use of the component is paramount to determine when specific rules apply that may affect how we manufacture the forging as well as special requirements for inspections during manufacturing: Some components must be surveyed and certified during manufacturing. If not completed at the correct manufacturing stages, a Classification Society Surveyor could stop the fabrication/installation processes that occur downstream from your component manufacturer. Your component could be subject to deviation at this point, or even rejection, at a critical time in the installation process, causing severe delays in scheduled repairs or new builds. The Scot Forge CS Advisor will work hand-in-hand with you, providing the expertise you need to eliminate risk. From spec to blueprint, we ensure your parts' manufacturability and compliance for the offshore; oil, gas and chemical; marine; military; government and power sectors. WHAT ARE SCOT FORGE CS ADVISEMENT BENEFITS? Management: Minimize Risks and Costs Scot Forge CS Advisors know working to Classification Society rule requirements cost time and money. Having a partner who comprehends the process can help minimize this cost and mitigate the risk of not meeting requirements. ABS Rules, for instance, require certification inspectors on-site during manufacturing, construction, or fabrication to verify the processes meet standards - and you pay for the time they are on-site. So, it's essential to understand the Rule requirements for your product to identify the stages in your supply chain where inspection and certification should occur. By working with a CS Advisor, you'll gain knowledge from our expertise to make empowered decisions saving your company time and money and minimize the risk of your products not being appropriately certified. As your partner in this process, we will likely ask a LOT of questions to ensure meeting all the design and Classification Society requirements for your component. Our team helps you ask the right questions upstream to gather all necessary project details and better prepares you for future conversations with your customers on new projects. Guidance: Meet Classification Society Supply Chain Requirements Our CS Advisors know it is critical for you to flow-down requirements to your suppliers – and your entire supply chain. We help ensure your requirements are clear and known throughout the supply chain to ensure your components are manufactured under the Rule requirements without delays or added costs. This flow-down is the most crucial aspect to ensure your component is certified accurately. Part Production: ABS, DNV-GL & Lloyd's Register Approved Forging Manufacturer Your CS advisor not only provides you with a dedicated service to help guide your parts through manufacturing, but you also work with a partner that is a uniquely qualified supplier in providing ABS-certified products and materials. At Scot Forge, we are one of the few U.S. companies that have been audited by ABS, DNV-GL and Lloyd's Register and APPROVED and achieved certification as a worldwide forging supplier. We work in ABS and Non-ABS Grades in Carbon Steel, Carbon-Manganese, Various Alloys, Stainless Steel, Aluminum, Copper, Titanium and Nickel Alloys up to 36,300 Kg (80,000 lbs.). WHAT IS A CLASSIFICATION SOCIETY? A Classification Society is an organization that provides classification, statutory certification and services pertaining to maritime safety and pollution prevention, based on marine knowledge and technology. Learn more . A well-known Classification Society is the American Bureau of Shipping (ABS) , chartered in 1862 to certify ship captains; it has helped develop and set safety and quality standards for ships and offshore structures. ABS standards are recognized globally and are used to ensure that the materials, parts and components, and construction of vessels and marine equipment meet established safety standards. HOW DO CLASSIFICATION SOCIETIES WORK? Classifications Societies work with the marine industry worldwide. They develop new technologies for constructing marine vessels and offshore structures, revising and updating the Rules to meet the changing industry needs. The Rules and Grades for component certification provide standards for the design, construction, and periodic survey of marine vessels and offshore structures to promote their safe design and assembly. Materials, parts and components used in the manufacture of marine vessel structures must meet the set standards for the specific application.

FORGING CONVENTIONAL ENERGY COMPONENTS Renewable Energy OEMs Are Forging The Future With Scot Forge At Scot Forge, we know how critical component reliability is to this sector of the energy industry. When companies extract, store, pipe or ship these fuels worldwide, the environment depends on critical components performing as expected when needed. We create precision-crafted, Forged Solutions, which our customers use when quality can’t be compromised. Many aspects of nonrenewable energy demand parts to withstand unforgiving environments with no room for error or failure, which is why OEMs turn to Scot Forge. TURBINES FORGE ENGINEERING Fossil fuels provide heat, light, electricity and many ingredients for things we use every day, such as plastics. They are relatively inexpensive to extract and, according to the Central Intelligence Agency, the world generates more than 66% of its electricity from fossil fuels and another 8% from nuclear energy. Energy Industry Forged Parts At Scot Forge, we can forge shapes for every portion of the conventional energy process. From mining and drilling to converting, shipping and storing conventional energy from natural resources, we forge generators, compressors, gearboxes, heat exchangers, blowers and more. Shafts: connecting rods for large diesel engines, industrial gas turbines and control rod drive mechanisms (CRDMs) Hollow Tubes: energy storage casings, reactor pressure vessels (RPVs), boiling water reactors (BWRS), nuclear waste storage containers and small modular reactors (SMR Discs & Blanks: nuclear grid blanks and industrial gas turbines, impellers, tube sheets and nozzles Complex Shapes: Nuclear waste storage container hatching Additional Shapes: Casings, spacers, centrifuge bowls, bearing blocks, shells and transition cones Rings: pump bearings and seals, Inconel end rings, crane gears Oil & Gas Extracting, such as deep-sea drill or fracking, and refining, such as petrochemical or oil refinement, require components to withstand high heat, pressure and corrosive environments during these processes, making forgings an ideal choice for the Oil & Gas industry power production. As crude oil is a fossil fuel that's used to make gasoline, diesel fuel, jet fuel, heating oil, lubricating oils and asphalt, our team understands that on-time delivery can be just as critical as part reliability. From ram and annular blowout preventers (bodies, doors/bonnets) to pinions and bull gears, our forgings exceed expectations. Natural Gas Mining natural gas is a process that looks the same as drilling for oil. Rock formations that contain natural gas deposits are drilled into until the gas deposit is located, with different places containing different types of natural gas: Conventional natural gas is in large cracks and spaces in rock formations Shale gas or unconventional natural gas is in tiny pores within rocks Associated natural gas is in crude oil deposits Freshly mined natural gas contains natural gas liquids (NGLs) like ethane, propane, butanes, pentanes and water vapor. This wet natural gas is then processed to remove the NGLs from the methane, which is then used for fuel. From drill heads for mining gas to hollow tubes for piping natural gas, our decades of experience, along with the time-tested relationships we have built with finishing shops, gives us the ability to help you reduce your material costs and allow us to support you and your timelines. Nuclear Power Nuclear power is the energy derived from a component of uranium called U-235. While uranium is not a fossil fuel because it is a common metal found in rocks, it's still considered a nonrenewable resource because U-235 is a rare uranium component. Our forgings support projects from nuclear reactor components and small modular reactors (SMRs) to radioactive waste storage and transport with unwavering reliability for the most critical applications. From new projects or maintenance to critical or time-sensitive situations, we understand the criticality of getting your parts to you on time with 100 percent compliance to the purchase order. Coal Even as the world moves toward renewable energy, coal is still one of the top energy-producing resources in the world, second to oil. On the other hand, in terms of electricity, coal generates more than 23 percent of the world's electricity mix, according to OurWorldData.org. There are four types of coal: Met Coal (Coke Coal) Anthracite coal with the highest heating value contains 86-97 percent carbon and is used in the metals industry. Bituminous coal is the most copious type found in the United States and contains 45-86 percent carbon, often used to generate energy and make iron and steel Thermal Coal Subbituminous coal with the lowest heat value contains 35-45 percent carbon. Lignite coal has the most moisture and lowest energy content; it contains 25-35 percent carbon and is used to generate electricity. With expertise in forging components for mining, which are found in the biggest trucks globally, draglines and electric rope shovels, along with competencies in concrete and asphalt industries, we offer a partnership that includes more than just manufacturing. We have the engineering skills to keep the mines running and the energy flowing.

FORGE CONSULTATION SERVICES FORGED PRODUCTS Forged Hollow Tube Advantages Cutting waste Reduced machining Improved integrity FORGE CONSULTATION SERVICES FORGED PRODUCTS Hollows Process Highlights Forging a hollow tube begins by making an upset preform, then punching a hole through the center. The preform is then drawn out over a mandrel to the specified length and O.D./I.D. configuration. Various Shapes Hollows can be produced not only in a straight cylindrical shape but with unlimited variations of O.D.s and I.D.s, including tapers. We also provide closed-end cylinders, both with and without flanges, in various wall thicknesses and cylinder end configurations to accommodate our customers' requirements. Forged Hollows Time & Cost Savings Because the inside diameter of the hollow is forged rather than bored from a solid bar, Scot Forge eliminates the need for additional machining, customers save time, money and reduce material waste. Scot Forge saves production time and increases part strength for customers by producing hollow parts, such as flange hollows, as single components rather than several components welded together.

Including the essential parts in the nacelle (gearbox, high-speed shaft, low-speed shaft and brake), the yaw drive for upwind turbines (shaft and gear) and tower components for both downwind and upwind turbines. Biomass Power Converting biomass to energy is done through various processes such as direct combustion, thermochemical, chemical and biological conversion – to create solid, gaseous and liquid fuels. The need for components to withstand high heat, pressure and caustic environments during these processes makes forgings an ideal choice for biomass power production. At Scot Forge, we have experience manufacturing forgings for kiln components, much like those used in the pyrolysis process and reactor components, like those needed for the hydrotreating process, to produce bio-oil, biodiesel, renewable gas and renewable jet fuel. Geothermal Power At Scot Forge, our expertise in markets relatable to the geothermal power extraction process makes us an ideal manufacturing partner for forging geothermal power generation components. Converting the Earth's natural heat into energy involves many parts we are familiar with, from forged bar used in drilling for steam to blades for turbines, shafts for generators and blanks for gearboxes. Hydropower Hydropower is converting water's kinetic energy into electricity. All but two states (Delaware and Mississippi) use hydropower in their energy mix. With decades of experience manufacturing components for turbines, we can support your project whether you are working with impulse turbines or reaction turbines. Many forgings like rings, discs and shafts are ideal for components such as blades, wheels and driveshafts for both turbines and generators. Solar Energy Solar energy is critical to the energy mix with a couple of energy harvesting methods. First, by exciting electrons, using panels allows for the collection and transfer of energy. Another technique uses heliostats to reflect the sun's rays and use thermal processes to heat water or salt and transfer energy. Solar energy harvesting employs turbines, and solar panels frequently require gearing in the manufacturing process, which are great applications for forgings.

Downstream processing such as heat treatment, testing, machining, segmenting, parting or splitting can all be performed in-house Guaranteed delivery programs OPEN DIE RINGS ROLLED RING ADVANTAGES At Scot Forge, we produce seamless rolled rings using an open die forging method or our ring rolling mill. Forged seamless rings are incredibly durable and reliable because they have inherent, circumferential grain structures and no weldments, eliminating weak points. Our seamless ring rolling mill is also a more cost-effective forging process than other methods because less starting stock is required to manufacture the ring. As a result, there is less material to machine away from the end product, another added benefit. When combined with a ring expander, ring rolling generates exceptionally round and durable ring products in any forgeable material. Seamless Ring Rolling Process The seamless rolled ring forging process starts with heating a pre-cut billet, then the malleable metal is placed on a hammer or press. The ring shape begins with a centerpiece "snapped" from the pre-form to produce a hollow center, similar to a donut, and moved to the ring mill. Once on the ring mill, the center of the part supported by a mandril and rollers apply pressure from different angles to gradually expand the ring. Rings made on a press are placed on a pin, supported by a saddle, then rotated as force is applied to expand the opening. Both techniques create circumferential grain flow creating the desired dimensions of the forged ring. This is our high-tonnage Wagner ring mill and ring stretcher in action! The Wagner allows us to produce: Straight rolled rings Contoured rolled rings The additional processing on our custom-engineered ring stretcher/sizer helps to minimize stock allowances, improve concentricity and cold-work aluminum rings.

At Scot Forge, our Power Generation team is well-versed in the technical specifications of hydropower forging designs for large-scale projects. From wicket gates to turbine shaft components, we manufacture cutting-edge solutions to fix your most complex repairs. Our team works with one-off projects such as supplying forgings for maintenance on the Hoover Dam or repeat projects, which allows you to get ahead by scheduling your forgings to arrive when you need them, enhancing your supply chain. At Scot Forge, we look to be more than just a manufacturer; we want to be a partner in keeping your energy flowing. QUALITY ASSURANCE POWER GENERATION FORGINGS Forged Parts For Hydropower Generation Forged Shafts – Turbine shaft components, generator rotors, wicket gate shafts, guide bearings Forged Complex Shapes – Wicket gates, gate components, bolts, thrust runners Forged Hollows – Bearing sleeves, packing sleeves Forged Rings – Wear rings, break rings, collars Forged Discs – Circular discs for runner applications Hydropower Applications Different Types of Hydropower Facilities Conventional dams are not the only source of hydroelectric power generation; from pumped storage facilities to run-of-river sites, there are various ways to harness hydropower. With each application comes its own set of benefits and electrical output capabilities. Dams/Impoundment: Impoundment facilities, most often referred to as dams, generate energy by releasing water from an upper reservoir. The water flows through a turbine that activates and spins a generator, which produces electricity. These facilities are not solely dependent on the natural flow of water, and the larger the reservoir is, the more storage that can be provided for future energy generation. Because of this, impoundments can flexibly generate energy that meets both baseload and peak load energy demands. Pumped Storage: Pumped storage acts as a battery by moving water between two reservoirs. Water is pumped through penstocks from a lower reservoir to a higher one, which stores energy, and is then released back from the upper reservoir through turbines to generate electricity when there is demand. These facilities can compensate for demand-driven fluctuations and are an efficient form of bulk energy storage. Run-of-River/Diversion: Diversions, often called run-of-river facilities, channel water through a canal or penstock using river water’s natural flow. Because these facilities are reliant on the constraint of incoming water movement, the electrical output varies. Hydroelectric Turbines Whether you’re working with impulse or reaction turbines, both play a critical role in keeping your hydropower facility running efficiently. Impulse Pelton Turbine Pelton turbines are impulse-type turbines that use the pressure of water to move the turbine. Peltons are very efficient and rely on a drive wheel with buckets that catch water and transfer its energy to the generator. Our forgings for turbine components are used in applications such as the drive wheel, also called the runner, to provide quality and reliability where it matters most. So, whether it be an unforeseen emergency or a scheduled H-mod, you can count on us to follow through and deliver for all your hydropower needs. Reaction Kaplan Turbine The Kaplan turbine is one of the more widely used turbines in the hydropower energy industry. Because of the axial flow principle, Kaplan turbines work more efficiently at low water head and high flow rates than other turbine types. As a result, these turbines are ideal for well-ordered electricity production. However, while it is one of the most modern turbines, it can come with a hefty price tag to install and maintain because of the moving parts. This is why choosing a suitable material is critical for turbine longevity. Stainless steel grades help protect against cavitation and corrosion, providing your dam with quality forgings that will last and require fewer weld repairs. Francis Turbine Francis turbines, found in medium to large-scale hydropower facilities, mix reaction and impulse turbines. As the blades turn, they utilize both the reaction and flow of water to create power more effectively. Francis turbines are designed and assembled for a broad scope of heads and flows, making them the most commonly used hydroelectric turbine. Our technically trained team, from sales, engineering, production and testing, is experienced in developing forgings for Francis turbines, including shaft, drive wheel and guide bearing forgings.

RENEWABLE ENERGY FORGE CONSULTATION & CUSTOM ENGINEERING We want to be more than just a manufacturer meeting your needs. We want to be a partner in getting our world to net-zero emissions by helping you discover opportunities and overcome challenges that energy storage presents, which according to Sandia National Laboratories, include: Offsetting the need for additional peaking generation capacity and reducing equipment wear, fuel use and air emissions. Enabling effective, optimal integration of intermittent renewables and possibly baseload renewables. Providing secondary services, helping distribute the electrical follow and supply reserve capacity, which will probably become a crucial element of the Smart Grid, facilitating 'demand response' resources. Giving utility planners and engineers flexible, reliable, and possibly less-risky alternatives to investments in conventional energy. Addressing growing electric service power quality and electric service reliability challenges, possibly by enabling utilities to provide differentiated electric service with higher quality and/or reliability. Forging for Energy Storage Including: Pumped Hydroelectric Energy Storage. A popular form of energy storage, pumped-storage hydroelectricity is typically designed to store excess power from the grid. Using the excess electricity to pump water up to a reservoir can be stored then released when demand rises. Similar to hydropower, once released, the water flows down through a turbine to generate electricity. The turbine/generator is similar to typical hydroelectric power plants that do not incorporate storage. Compressed Air Energy Storage. Compressed air energy storage (CAES) involves using excess energy to compress air at up to 1,000 pounds per square inch, creating a high-pressure system in a series of large underground chambers. This energy storage method is coupled with wind energy. When the wind speeds slow or power demand surges, the pressurized air energy, typically mixed with a bit of natural gas, is released to spin turbines turning generators to create electricity. Flywheel Energy Storage. Flywheel electric energy storage systems include a shaft connected to a cylinder that spins rapidly within a vacuum-sealed enclosure attaining rotational speeds up to 60,000 revolutions per minute. Some flywheels use magnetic bearings to levitate the cylinder, thus limiting friction-related losses and wear. Excess electricity is used to accelerate a flywheel (a type of rotor) through which kinetic rotational energy is stored. When the electricity is needed, the stored energy is converted via slowing the flywheel's rotational speed through a shaft that turns a generator. Thermal Energy Storage. Electricity can be used to produce thermal energy. According to the International Renewable Energy Agency, "coupling heating systems with thermal and seasonal storage offers important flexibility in demand in regions where winters are particularly harsh. For example, the Drake Landing Solar Community in Canada uses a long-term thermal energy storage system to store heat from solar collectors during summer for space heating during winter. In coupling the power and thermal sector, Siemens-Gamesa is testing a thermal energy storage system that uses wind power to produce heat stored in over 1,000 tons of rock. This system provides a thermal storage capacity of 130 megawatt-hours of electric energy at rated charging temperatures of 750°C. IRENA estimates that around 234-gigawatt hours of thermal energy storage are present, a crucial enabler of reliable, secure and flexible energy systems." Superconducting Magnetic Energy Storage. A superconducting magnetic energy storage system (SMES ) stores electricity as a magnetic field in an environment cooled below the temperature needed for superconductivity. As long as this temperature is maintained, energy can be stored indefinitely because the current will not degrade. Additional SMES components include power conditioning equipment and a cryogenically cooled refrigeration system. Methane. Researchers have developed a way to take the products of biomass gasification to produce methane, which is then be burned to power turbines. Methane essentially serves as an energy storage medium and can be stored or easily piped/shipped using the existing natural gas infrastructure.

At the heart of the operation is our custom-designed, computer-controlled GFM single-stand planishing mill. Through a series of reversing passes, the planishing mill rolls the bar to a smooth surface in less than five minutes. While still hot, the bar moves down the GFM mill to the Braun abrasive saw station for trimming. A 16’ round can be cut in less than half a minute. To complete the process, the bar is end-stamped for traceability by an automated programmable marking system. The bar is then slowly rotated down an automatic uniform cooling bed to maintain straightness. Since the bars can be produced so efficiently in the planishing mill, delivery times are reduced. Unlike traditional hot-rolled bars, which can only be manufactured in large runs, forged Tartan Round Bars can be purchased in quantities as small as the product of one ingot.

Advantages of Forgings & Forging Processes Forging 101 - What Is Forging? At its most basic level, forging is the process of forming and shaping metals through the use of hammering, pressing or rolling. The process begins with starting stock, usually a cast ingot (or a "cogged" billet which has already been forged from a cast ingot), which is heated to its plastic deformation temperature, then upset or "kneaded" between dies to the desired shape and size. In the next several pages, you can learn the basics about the open die and rolled ring forging process, its applications and benefits. STRUCTURAL ADVANTAGES ECONOMIC ADVANTAGES Comparative Analysis We know that you have many options for manufacturing your key components so here is a brief overview of: Forgings v. Machined Bar Forging v. Weldments/Fabrications Forging v. Castings Forging v. Centrifugal Castings Forging v. Torch Cut Plate Forging v. Closed Die/ Impression Forging Metal Forging Process When buyers must select a process and supplier for the production of a critical metal component, they face an enormous array of possible alternatives. Many metalworking processes are now available, each offering a unique set of capabilities, costs and advantages. The forging process is ideally suited to many part applications; however, some buyers may be unaware of the exclusive benefits available only from this form of metal forming. In fact, forging is often the optimum process, in terms of both part quality and cost, especially for applications that require maximum part strength, custom sizes or critical performance specifications. There are several forging processes available, including impression or closed die, cold forging, and extrusion. However, here we will discuss in detail the methods, application and comparative benefits of the open die and seamless rolled ring forging processes. We invite you to consider this information when selecting the optimum process for the production of your metal parts. A historical perspective on metal forging To meet the changing needs of industry, forging has evolved to incorporate the tremendous advances in equipment, robotics, computers and electronic controls that have occurred in recent years. These sophisticated tools complement the creative human skills which, even today, are essential to the success of every metal forging made. Modern forging plants are capable of producing superior-quality metal parts in a virtually limitless array of sizes, shapes, materials and finishes. During this hot forging process, the cast, coarse grain structure is broken up and replaced by finer grains. Shrinkage and gas porosity inherent in the cast metal are consolidated through the reduction of the ingot, achieving sound centers and structural integrity. Mechanical properties are therefore improved through reduction of cast structure, voids and segregation. Forging also provides means for aligning the grain flow to best obtain desired directional strengths. Secondary processing, such as heat treating, can also be used to further refine the part. Forging can create a myriad of sizes and shapes with enhanced properties when compared to castings or assemblies.
