Challenges & GapsGoal: Identify challenges and gaps for
offshore renewables to further knowledge and develop a tactical plan for offshore deployment
What is it?The following is a list of challenges and gaps
from various points of view.The challenges and gaps were developed by
experts from industry, academia and government
Energy Projections & Performance CHALLENGESTemporal/spatial variability of resourcesLack of data Model validationInstrumentation including remote sensingData and modeling (extreme events, hurricanes etc)Uncertainty/ data quality
Knowledge/RequirementsAccurate characterization of wake lossesDynamic info system for sitting and array
designHomogenous baseline data before and after
deployments
Knowledge/RequirementsIntegrated marine data sets (atmosphere and
ocean)Enhanced data managements and sharing
methods (particularly including the private sector)
GAPSMetocean profiles to 200M at relevant
locations including horizontal variabilityNew robust remote sensing technologiesCentralized metocean dataInternational collaborations
GAPSDatabase for extreme eventsEnhanced IEC standards for large systems
and offshore applicationsAir-Sea coupling physics (with waves)Connections between geophysical conditions
and operational loss factors
Operations Planning & Sight SafetyCHALLENGES:Operations and maintenance Extreme event responsSafety (public and operational)Installation and constructionMonitoring/current
ChallengesFuture (next hour to next decade predictions)Adapt to offshore environment ( wind chill)
GAPS & CONCERNSScour/bottom typeLightningAir/Precipitation
FACILITY DESIGN: CHALLENGESDesign for extreme eventsLack of guidance/standardization
methodology for determining site specific design conditions
Validation of modelsReducing uncertainties-both investment and
environmental risks
CHALLENGESKeeping devices in the waterCosts and availibilty of material and feasible
designs
GAPSCommon dataValidation of remote sensing technologies for
financing purposesA complete wind solar profileArray simulation capabilities needed to
optimize facility layout
GAPSHigh fidelity structural & aerodynamic device
simulation capabilities are needed More observation for site characterizations
FORECASTING:CHALLENGESLack of good data for wind and wave
couplingNo real time financial incentive to get
better/longer dataNo real info on what the industry needsLack of public/private interactionData sharing across the industry
GAPSHigh performance computingData on ocean temperature,salinity,
density,waves, currents
TECHNOLOGY DESIGN & VALIDATION
CHALLENGES:Cost competitive designsReliable/durable technologies
