Wind power is a clean and renewable energy source. Wind turbines harness energy from the wind using mechanical power to spin a generator and create electricity. Not only is wind an abundant and inexhaustible resource, but it also provides electricity without burning any fuel or polluting the air. The wind sector in India has been rapidly growing in recent years, with the country being fourth largest producer of wind energy in the world. According to the Ministry of New and Renewable Energy (MNRE), India's wind energy capacity has reached 41.9 GW as of February 2023. National Wind Solar Hybrid Policy announced in May 2021 with a aim to promote large-scale grid-connected wind-solar hybrid projects in the country. MNRE has also recently issued a draft guideline for the development of offshore wind energy projects in India. It is expected to accelerate the growth of the renewable energy sector in India and contribute towards achieving the country's target of 450 GW of renewable energy capacity by 2030. Steel as key component One key component in the construction of these turbines is heavy steel plates used for durability, strength, and versatility. Heavy steel plates are an essential component in the construction of wind turbines. They are used for a range of applications, including the tower, foundation, and rotor blades. In the tower, the plates are used to provide the structural support necessary to withstand the strong winds and turbulent conditions at higher altitudes. The foundation requires heavy steel plates to support the weight of the tower and ensure stability, while the rotor blades require plates for their internal components, such as the hub and pitch system. The use of heavy steel plates is especially important in larger wind turbines, which require stronger and more durable components to withstand the increased stresses and loads. For example, the latest generation of offshore wind turbines can have a rotor diameter of up to 220 meters and stand over 250 meters tall. These turbines require steel plates that can withstand high wind speeds, waves, and corrosion from the harsh marine environment. Another advantage of heavy steel plates is their flexibility in design. Wind turbine manufacturers can customize the plates to meet specific project requirements, such as thickness, width, and length, depending on the turbine's design and location. This flexibility also extends to the type of steel used, with manufacturers able to choose from a range of high-strength, low-alloy steels, and carbon steels. There is a growing need from the wind tower segment for steel solutions, value engineering, cost cutting and improved efficiency in operations. Value propositions from AMNS for wind segment Supply of TMCP plates against furnace normalised/normalised rolled plates for improved weldability and handling Supply of steel plates as per exact design, and tight dimensional tolerances High strength steel (S420) replacing standard S355 grades Cost saving model for use of high strength steels (welding, handling, cutting, etc.) Advantages of wider widths Reduction in the number of shells in the tower section Savings by elimination of additional operations like, cutting, handling, welding, assembly, etc. Reduction of circumferential welding -30 per cent cost saving through reduction of welding Advantages of high strength Taller towers for enhanced power generation Greater stability and integrity of structure Cost saving due to reduced weight of shells and stiffeners Overall, the wind sector in India is witnessing significant growth and development, with the government taking various initiatives to promote wind energy in the country. The latest happenings in the sector indicate that the industry is moving towards greater efficiency, reliability, and sustainability. With the right policies and investments, the wind sector in India has the potential to become a major contributor to the country's energy mix and play a key role in reducing greenhouse gas emissions.

Handling concrete better

Efficiently handling the transportation and placement of concrete is essential to help maintain the quality of construction, meet project timelines by minimising downtimes, and reduce costs – by 5 to 15 per cent, according to Sandeep Jain, Director, Arkade Developers. CW explores what the efficient handling of concrete entails.Select wellFirst, a word on choosing the right equipment, such as a mixer with a capacity aligned to the volume required onsite, from Vaibhav Kulkarni, Concrete Expert. “An overly large mixer will increase the idle time (and cost), while one that ..

Elevated floors!

Raised access flooring, also called false flooring, is a less common interiors feature than false ceilings, but it has as many uses – if not more.A raised floor is a modular panel installed above the structural floor. The space beneath the raised flooring is typically used to accommodate utilities such as electrical cables, plumbing and HVAC systems. And so, raised flooring is usually associated with buildings with heavy cabling and precise air distribution needs, such as data centres.That said, CW interacted with designers and architects and discovered that false flooring can come in handy ..

The Variation Challenge

A variation or change in scope clause is defined in construction contracts to take care of situations arising from change in the defined scope of work. Such changes may arise due to factors such as additions or deletions in the scope of work, modifications in the type, grade or specifications of materials, alterations in specifications or drawings, and acts or omissions of other contractors. Further, ineffective planning, inadequate investigations or surveys and requests from the employer or those within the project’s area of influence can contribute to changes in the scope of work. Ext..
