Wind Energy department at IFE

• IFE has had an organization unit with wind energy R&D as primary focus for 40 years

• Offshore wind turbines has been the primary focus the last 12 years.

• Wind energy pinpointed as area of strategic focus for IFE

5

Primary markets for IFE Wind Department

• Offshore wind turbines

• Offshore wind farms

• Onshore wind turbines and farms

6

What we do – R&D for industry

• We have significant experience with most offshore wind turbine concepts, both bottom fixed and floating

• Develop and/or analyze complete offshore wind turbines or their components

• Assist engineering, enabling them do what they want themselves

• Designs detailed realistic wind turbines for the industrial that they can use for internal R&D

The tension leg buoy (TLB)

What we do – Integrated simulations

• 3DFloat is a state of the art software developed by IFE for simulating complete offshore wind turbine

• Can also be used for other structures exposed to wind and/or waves

• We:• Develop it• Sell it to the industry• Provide simulation services• Customize it to industry project needs

8

OO-Star in extreme waves

What we do – CFD

• CFD = Computational Fluid Dynamics

• We use CFD when higher accuracy or details are needed then what simplified models can produce

• We use state of the art commercial tools• Develop validated methods that allows CFD to be

used in new areas• Not just pretty pictures. We are at a stage now

were we can replicate experiments quite accurately

Replicating experiments with a faulty turbine

Secondary markets for IFE Wind Department

• Other areas where our partners and customers seeks our assistance and our competence can be of help:

• Examples• Structures exposed to wind and/or waves• Floating bridges, 3DFloat is a preferred industry tool for design of the E39 Bjørnafjorden bridge• Floating solar• Top level sports equipment

Project example: KPN NEXTFARM

• Work: Develops tools that are both very accurate and fast for simulating the loads and performance for all the individual wind turbines in a farm

• Main planed innovation: Will be the first tools that can produce state of the art accuracy simulations for all turbines in a farm at near real time speed

• Industry benefits • Design windfarm with lower LCOE (Levelized Cost of

Energy)• Better operation of wind farm by taking into account

state, hourly wear and production of the individual turbines vs. the electricity price at that time

• Get the most out of an existing farm by life time and life time extension planning and control

Project example: KPN DIMSELO

• Work: Compare existing and project-developed wave and wave load models with respect to dimensioning loads for offshore wind turbines

• Main innovation: Tool that for the first time made it possible to model highly realistic waves at engineering speed

• Industry benefits • More realistic engineering speed models for waves and

wave loads• Knowledge about how calculated fatigue and extreme

loads vary with different models allowed in standards

• 2014-2018
