IntroductionWTG OEM’s role For Foundation Design Optimisation
● For offshore wind farm design, support structure design
is site specific
● Design optimisation to achieve the most cost effective
site specific solution is complex and time consuming
● As for any structures, design is driven by the various load
contributions and, therefore, the focuses are:
• to reduce the loads on support structure
• to realise integrated load evaluation by utilising representative and efficient calculation method and process.

Various foundation load reduction features are developed
for design optimisation.
● Passive Tower Damper (PTD)
● Active Side-Side Tower Damper (A-SSTD)
● Active Fore-Aft Tower Damper (A-FATD)

To support foundation design optimisation, MHI Vestas is committed
to;
● Develop various foundation load reduction features / damper
technologies (Passive tower damper, Active SSTD, Active FATD,
etc).
● Provide flexible interfaces in integrated load assessment
toward foundation designs.
● Develop new technologies to further support foundation design
optimisation (e.g. SMART Foundation Loads for V164)
