INNOVATIVE ANCHORING SOLUTIONS
MAKING WIND TURBINE ASSEMBLY AND MAINTENANCE A BREEZE
In the constantly changing landscape of the wind power industry, turbine design is being taken to new levels in order to maximize efficiency. Larger parts with tighter tolerances are being used, higher quality materials are demanded, reliability is essential, and cost-efficiency is a must.
the company make wind turbine manufacturing and maintenance simpler, faster and more cost effective.
With over forty years of experience in industrial bolting technology, the company is the world’s oldest and largest manufacturer of hydraulic and pneumatic torque wrenches and is dedicated to providing the highest level of customer service by continually developing new products to make bolting jobs as safe and hassle-free as possible.
ORGANISATION
HYTORC has been involved in turbine assembly since the early days of the industry, and has invested heavily to stay ahead of the curve on its progression. New bolting techniques and products from
HYTORC has worked hard to build a worldwide wind network to provide fast service and quick turnarounds in every area of the world. Their headquarters is located in Mahwah, New Jersey in the
CRITICAL BOLTING AND COMPETENCY
Currently loss of containment is the greatest documented cause of petrochemical accidents. Everything from water, steam, gas and liquid can have profound effects on the outcome of any incident and therefore should be deemed critical.
Loss of production, increased maintenance costs, financial penalties for excess fugitive emissions or even more disastrous consequences can arise from the lack of integrity in pipe joint assembly.
Compare the traceability and verification of skills and competency in the example
pipeline joint shown below. There are two areas which could be deemed as critical to the integrity of the line. The first is the welded section just ahead of the bolted joint, currently records would be held which would show the certification of the materials used, the welding procedure, documented confirmation of integrity via NDT and the qualifications/competency and identity of the individual welder.
Compare this with the next section of critical integrity which is the bolted flange area, at best current practices may record the gasket type used, the name of the individual who completed the joint and
USA and offices and/or representatives can be found in nearly every country.
WIND POWER HEADQUARTERS A newly developed Wind Power Headquarters was opened in 2008. More specially designed HYTORC bolting tools are used daily in the wind industry than all other brands combined - their products are CE, TUV & ISO 9001:2000 approved.
WIND SPECIALISTS
In the early stages of the wind power industry, HYTORC discovered a need for reliable equipment and, more importantly, dedicated, knowledgeable representatives.
The company responded by hiring specialists that had worked in the wind power industry and were familiar with the many different manufacturers of wind turbines. The next step was identifying the different obstacles that each manufacturer was facing during turbine assembly and/ or maintenance and working together with HYTORC’s highly experienced engineering staff to provide a solution.
RECENT DEVELOPMENTS In the last five years alone kits have been developed for nearly every application on the various turbines offered by every manufacturer in the industry. With specialists engineers available for free on- site supervision and training in nearly every
perhaps details of the torque requirements for the joint. However there is currently no requirement for the individuals to be trained and recorded and proved competent in this critical task.
LEGISLATION
This is set to change as draft legislation, CEN/TS 1591-4 which was issued in 2007 is now being driven by Europe and has been adopted as current best practice. This standard forms the basis of the proposed legislation currently awaiting EN status and clearly states “the integrity of a bolted joint is key in any pressure containment system and should be subject to personnel competence”.
The aim of this standard is to offer a procedure for training and competency assessment of personnel who disassemble, assemble and tighten bolted joints under the Pressure Equipment Directive 97/23/EC.
