As part of a recent UK investment program, Sulzer has built and equipped a dedicated in-house test and development laboratory for high voltage coils. Other aspects of the program include upgrading key items of manufacturing equipment at the company’s Birmingham based Center of Excellence for coil design, manufacture and supply. These latest developments will enable the company to offer both a wider range of coils and shorter lead times for products that require extended insulation system tests. Manufacturing high voltage (HV) coils is a precise science; and there are many differences between insulation systems that must be accommodated depending on the application. Hydro-electric generators for example are especially challenging to refurbish and require high specification coils that are guaranteed to deliver an extended service life. In contrast, smaller high voltage motors usually require a faster turn-around and a cost-effective solution to justify repair over replacement. Sulzer’s investment is guided by its policy of providing the highest quality service, globally. One which the company believes should encompass superior quality repairs, the ability to service challenging applications, provide long service life and deliver fast turn-arounds. Precision and speed The key to performance and reliability of copper coils within HV equipment is the insulation system that is

Hamburg, 29 June 2018. The Nordex Group is supplying ABO Wind, an international project developer, with two N149/4.0-4.5 turbines, each with a nominal output of 4.5 MW, for the "Wennerstorf II" wind farm. Less than eleven months have passed since the launch of this powerful turbine type and now building permission has been granted for the site to the south-west of Hamburg. Following its installation over the course of this year the Nordex group will conduct sound level and performance tests, among others, on the turbines, and this will form the basis of the IEC certification. This order also brings the total amount of wind energy projects installed worldwide jointly by ABO Wind and the Nordex Group to 500 MW. The "Wennerstorf II" site is characterised by wind speeds of around 6.5 metres per second. Thanks to the low level of turbulence at the site, the N149/4.0-4.5, the output of which can be variably configured between 4.0 and 4.5 MW depending on site conditions, can be operated at its maximum level of 4.5 MW. The large rotor sweep of the N149/4.0-4.5, its high rated capacity, and the hub height of 125 metres, all mean that the wind farm will generate an annual

A damaged main engine cylinder casing has now been returned to service in Bulgaria, after a repair operation lasting just seven days, saving almost eight months of off-hire time. The shipowners, faced with an eight-month replacement estimate for the engine, called in local Metalock engineers who worked to perform a full repair. The entire operation took one technician, seven days and was conducted without removal or disassembly of the engine. Details of the repair have been released by the Metalock International Association (MIA), in a whitepaper,‘The Benefits of the Metalock Process', highlighting the loss to shipping caused by unfamiliarity with the Metalock technique. Many of today’s engineers, says the whitepaper, were simply never taught about metal stitching, and believe their only option to deal with cracked machinery is welding or replacement. Since welding cast iron is at best a sticking plaster approach, owners can be faced with enormous replacement bills and long periods off-hire. A new campaign by MIA now aims to fill the knowledge gap. “We want to restore a vital missing tool of the Chief Engineers’ toolbox” says Andre Mortimer, President, of the Metalock International Association, which has member companies in over 70 countries. “Between 70 and 90% of Metalock repairs by

Responding, Fabrice Leveque, Senior Policy Manager at Scottish Renewables, said: "This is a stark warning from the independent advisory body that the UK Government is unnecessarily increasing the cost of tackling climate change by preventing the cheapest technologies, like onshore wind and solar, from competing in the electricity market. "Enabling parts of the UK, and particularly Scotland, to deploy more onshore wind could provide a net payback to consumers of £1.6 billion and create 8,500 new long-term jobs. "The report also warns that in other areas, like heat and transport, the UK Government has too few policies with too little ambition and that, as a result, the UK is off-track to hit its future emissions targets. "Low-carbon sectors need long-term clarity on future policy if they are to continue to deliver economic and environmental benefits across the UK."
