Offshore design

OFFSHORE ROBUSTNESS

For harsh conditions at sea

•Extremely robust Nacelle design – ability to close air intake holes and service hatches

• Applying the learnings from the V90-3.0 MW experience

Optimized to be a low-risk option for offshore conditions

SERVICABILITY & SAFETY

For improved serviceability

•60% increased space in nacelle vs. earlier models

•Majority of components plug-&-play for easy exchange

•Components designed with first-in-kind virtual reality tool for optimized service

OFFSHORE POWER

For no risks at sea

•Adapted rating

•Adapted turbulence class

•Optimized rotor speed –

balance between energy production and loads is a key factor for sucess

Virtual Reality helps you make

sure that service technicians

can perform their jobs safely

Visualisation and simulation

technique allows Vestas to

communicate and move

knowledge much faster to you

First nacelle designed with

technicians in the Virtual

Reality Centre to ensure good

working environment (easy

access to tools, enough space

to do service, etc.

Offshore Serviceability Achieved with unique tool for service-optimized hub design and maintenance manuals

Lost Production Factor of Vestas’ installed fleet, all

models, offshore and onshore (%)

Lost Production Factor is…

•Showing the % of MWh lost due

to turbine down-time

•Impacted by:

- thoroughly tested quality

- improved design

- optimised service

- turbine monitoring

- optimal siting

- spare-parts logistics

•Higher in the start-up phase of a

product and each park than over

the whole life-cycle

Commissioning


“Considering the Thanet site conditions,

the V90 turbine was the obvious choice.

We have enjoyed working closely

together with Vestas to deliver world-

class project performance at Thanet, and

will definitely consider Vestas for any

future projects.”

Ole Bigum Nielsen

Project Director, Vattenfall

Vestas Experience More than a decade producing offshore wind turbine energy


Lost Production Factor has been reduced an order of magnitude in a

constant improvement process that have taken more than five years.

Availability and MTBI has been dramatically increased in the same period.

The changes of these variables are not continuous because of the effect of fleet

size and particular solutions to particular problems.

Safety index has been improved three times due to procedures improvements

Design of new machines for offshore marked should be based on

experience.
