! Transportation & Installation! !

When Vestas set out to establish a new benchmark for efficiency with its development of the V90 3 MW turbine, high priority was given to keeping weight down. The result is a showcase of innovative engineering – particularly as regards weight saved. Following the development of 2 MW platform, 3 MW Vestas was built to control loads on specific tower heights. This principle helps to reduce weight of the turbine and loads on the tower and foundation. This cuts your unnecessary foundation costs.

! Service and Maintenance! !

A series of improvements to the V90 have made service and maintenance calls less demanding – and less frequent. Turbine access has been simplified and working areas expanded, while the arrangement of tower and nacelle components has been optimised to facilitate service procedures.

!

! Optimization, Upgrades and other services! !

We aim not only deliver the best quality product, but improve its condition, customize it for your needs to strengthen the certainty of your investment in wind energy. Such services as retrofit with provided warrantees, software and other upgrades, re-built to 60 Hz and others are available on request.

! Full Maintenance Concept! ! For investors from some countries (list on request) we can offer a full maintenance Concept based on long ter m agreements for service and maintenance, online monitoring, optimization and trouble-shooting. Full maintenance concept ensures you with maximum power generation, preventive maintenance and benefits on saving many service costs.
