  • DRIP by DRIP

    Dam safety has become a focal point of attention across India, where the World Bank is supporting an initiative to assist with rehabilitation, safety and project management.

  • Safety is no accident

    The prevention of tailings dam disasters is described as being an ambitious and challenging goal, made more difficult by the competitive, international and cyclical nature of the mining industry. Sixteen years ago ICOLD issued recommendations for change, and although tailings management has improved in some areas, the mining industry still fails to achieve a zero-failure rate. Suzanne Pritchard looks at a recent report by the United Nations Rapid Response Assessment Series, which hopes to encourage action to make zero catastrophic incidents become a reality.

  • The modern dam engineer

    Like many industries, the dam industry is influenced by both internal and external factors which can prompt change. IWP&DC was interested in finding out if such elements have affected the engineer’s working life when inspecting dams. We asked members of the industry for their own thoughts about the role of the modern dam engineer: Has this changed in recent years? Are engineers faced with increased challenges? And will this role continue to evolve?

  • Thor™ 115: a new ferritic steel for advanced power plants

    A new 11% Cr ferritic steel from Tenaris, Thor™ 115, can provide a proven alternative to grade 91 (9 % Cr) in typical applications, but also, thanks to its lower steam oxidation rates, promises superior performance in more demanding situations, at temperatures above 600°C, significantly extending the range of application for ferritic steels, potentially up to 650°C.
    The new material has been subjected to extensive tests and manufacturing trials, which have successfully demonstrated microstructural stability, excellent chemical and physical properties, together with good weldability and manufacturability. Simone Baietta and Erick Escorza, Tenaris

  • Beatrice – an uplifting story

    At the £2.6 billion Beatrice offshore windfarm project located 13 km off the Caithness Coast of northeast Scotland, construction is continuing at a good pace. The project, located in the Outer Moray Firth off northeast Scotland, is led by energy giant SSE and at 55 metre sea depths is at one of the deepest wind farm depths in the world. It will be capable of generating enough electricity to reduce annual CO2 emissions by 850 000 tonnes.

  • Siemens HL: the bridge to 65%+ efficiency

    In an era of inexorably increasing renewable capacity and growing interest in distributed generation do large gas turbine based power plants have a role? Siemens believes they do, but efficiency and operating flexibility need to be pushed to unprecedented levels, as in its new HL gas turbine offering. James Varley reports from a Siemens briefing on the HL in Berlin given by Karim Amin, president of global sales, and Guido Schuld, product family owner, large gas turbines.
