NEW COURSE AT HETA GETS INDUSTRY “TORQUING”
HETA (Humberside Engineering Training Association) have designed a new training course for the Wind Energy industry.
COURSE DESIGN
This course is designed for Mechanical or Structural Engineers who are required to complete bolted connections to a uniform bolted torque setting. It also helps them develop the knowledge and practical experience to professionally complete electrically powered hydraulic bolt connections.
The qualification shows potential customers that individuals are competent installers or testers, and are up to date with national requirements for the industry (BS7671).
COURSE CONTENT • Health & Safety issues • Introduction to equipment and identification
• Equipment assembly and operation • Equipment operation parameters • Benefits of lubrication during bolt torqueing
• Practical demonstration of equipment • Familiarization and use of equipment • Practical assessment • Theory assessment
Bolt Torquing is a 2 day course that covers a range of topics around the safe use and practice of electrically powered hydraulic bolt torquing equipment. It is a 2 day course and available at either HETA’s Hull and Grimsby sites, as well as on site at your company if necessary.
HETA’s Marketing & Communication Manager, James McIntosh said “We had several enquiries from our customers who were asking for courses on Bolt Torquing. We then took the opportunity to develop a course that was relevant
to our client companies from the Oil & Gas industry, as well as the renewable companies we train for. Bolt Torquing is just one of a whole range of adult courses we offer at HETA as we look to establish ourselves further in the renewables market”.
EXPERIENCE AND AN ENVIABLE CLIENT BASE
HETA have been training engineering and manufacturing advanced apprentices since 1967 across Humberside. Their number of client companies is currently over 150 including BP, Reckitt Benckiser, Saint Gobain Glass, Smith & Nephew, Conoco Philips, Total LOR, Centrica and many more.
BESPOKE WIND ENERGY APPRENTICESHIP
Over the last 2 years, HETA have developed a bespoke renewable energy apprenticeship to meet the demand of the wind industry. They now have 11 apprentices who are at various stages of the 4 year apprenticeship and looking to forge a career in Wind energy for Ecotricity, Blackrow Engineering, RES and Centrica.

REDUCED MAINTENANCE REQUIREMENTS – LEARNING FROM THE PAST
Remote and offshore locations increase the limitations and costs with regard to servicing and maintenance and the wind energy industry would be wise to follow the example of the offshore oil and gas platform operators.
In the mid 80’s, the industry began to recognise that major benefits could be gained by moving away from the traditional labour intensive and potentially highly inaccurate method of bolt checking using tightening tools.
ALTERNATIVE APPROACH The alternative approach, adopted to ensure bolted joint reliability, was to measure bolt tension during installation tightening by using RotaBolts throughout the structure instead of measuring tightening effort.
The result? – inspection and maintenance reduced by £10,000 to £15,000 per crane per year with the added benefit that equipment life has also been extended.

EMPIRICAL EXAMPLE This compares with the following empirical example for a land based turbine, which examines the costs of a 100% bolting inspection, obtained from three leading wind turbine manufacturers.
• Company (A) stated it takes 2 men 100 hours at 50 euros hour/man = 10,000 euros
• Company (B) stated it takes 2 men 80 hours at 50 euros /hour/man = 8,000 euros
• Company (C) stated it takes 2 men 60 hours at 50 euros /hour/man = 6,000 euros.
Using RotaBolt in place of standard bolts however, trials have confirmed that all the bolts in the turbine can be checked in 1 hour with those in the tower alone requiring just 30 minutes.
20 YEARS EXPERIENCE 20 years experience of assuring joint reliability in the offshore oil and gas industry
with the RotaBolt system has also shown that after the initial 100% bolt check, the next check can be 60 months later.
The result? – investment in RotaBolt pays for itself by the end of the turbine ‘A’ Test bolting check.
