Mooring Challenge
Why Polymer Can design in passive flexibility which reduces loads on the device Excellent fatigue and lifetime
Gator Polymer based pumped water PTO Opportunity to submit Gator concept to Wave Energy Scotland Power Take Off Call IP sitting on shelf Potential Benefits Seawater compatible Does not require seals 10’s of millions of compression cycles Fabricated at reasonable cost at all scales Low maintenance requirements Uses off the shelf hydropower components
Wave Energy Scotland very LCOE focussed CAPEX OPEX Performance per unit cost Affordability Efficiency (across Load Spectrum) Manufacturability Peak Performance Performance Scalability Capacity Factor (Load Factor) Installability LCOE Peak Loads Risk Fatigue Loads Reliability Consequence FMECA Maintainability Availability Frequency of Loading Cycles Survivability Corrosion Resistance Operability Load Shedding Ability Life Expectancy Bio-Fouling
Exceedence TfIMarine needed help converting our benefits into real LCOE predictions Needed a standard approach to doing this Needed to see the unanswered questions Needed a tool with substantial detail and power behind it Needed a tool which could highlight the relevant importance of the different benefits Approached Exceedence who had the tool and the capabilities to do this Helped us to form a project which matched WES requirements Focussed on top down LCOE (take existing LCOE estimates for a device and change based on Gator) Also asked them if them could manage the project
Gator – a compliant seal free hydraulic PTO Funded by WES PTO project Stage 1 – TRL 1 – 3
LCOE P/KWH 38 15 4 0.02 0.04 0.08 0.1 0.3 0.6 1 2 5 10 20 41 82 164 327 CUMULATIVE DEPLOYMENT GW
Moving Forward Excellent learning experience for TfI Strong LCOE results led to stage 2 approval for the Gator project Bottom up LCOE estimates (detailed engineering to determine costs from bottom up) Tfi are looking to buy Exceedence finance It’s a tool which we will use more frequently across multiple projects Helps quantify benefits at an early stage, focussing research & development efforts Further projects TfI have applied for additional WES projects with the Exceedence tool being a key part
