Innovative solution to reduce wind turbine down time

Challenge To improve wind turbine availability by

reducing turnaround times during bearing replacements

Bearings are a common failure, requiring an extensive outage for their replacement

Solution To develop propriety tooling and processes to

allow bearing change-out within the tower Ability to work at heights in confined space

Benefits Operator of wind turbine farm saved the cost

of hiring a mobile crane and the additional days of down time


Improving generator capacity through use of modern designsChallenge Increase the output of a generator

commissioned in 1963 by 16.7%

Solution Stator winding copper cross-section increased

improve efficiency Rotor winding and insulation upgraded Exciter fields upgraded and winding re-

designed to increase field forcing Stator core replaced to extend machine life

Benefits Additional 5MW of available generation

capacity created for the owner


Rapid return to service of a 38MW generatorChallenge To repair a 38MW generator as quickly as

possible following an earth fault

Solution Same day arrangements for transport to

Birmingham, UK (75 t) Stator core refurbishment and complete

rewind Rotor repair

partial repairs to damaged areas new resin-glass bands fitted and cured dynamic balancing

Benefits Generator returned to service within 28 days


Final stage blade modification extending lifecycleChallenge 28MW steam turbine rotor suffered excessive

vibration, broken last stage blade and damping wire

Solution Extensive testing pinpointed problem areas Damping wire size enlarged - stress reduced

to 34% of original Blade redesigned to shift frequency resonance Stress level at blade airfoil and hole decreased

38%

Benefits Increased safety and risk elimination Unit now running at full capacity with no

problems


High quality laser weld repair solutionsChallenge Demand for high-tech repairs to new materials

in gas turbine hot sections

Solution Highly flexible 5-axis laser machining center Ability to rebuild removed substrate by laser

metal forming or cladding Laser cutting and welding process integrated

Benefits Higher quality repair than standard process Higher process reliability and accuracy Reduced processing time
