The ChallengesFixed WD lt~50m and Distance to Shore lt~100kmFixed Challenges
bull Distances will reach well greater than 100km from shore putting pressure on cable design and dynamics
bull Floater also demands dynamic cables and high voltage
bull Environment will be harsh even OampG donrsquot normally bank on platforms in TRS areas
bull Challenges to determine adequacy of typhoon class and earthquake effects on turbines moorings cables construction and OampM
Cost reduction in floating wind is a major challenge

Scale construction amp operational challenges
bull Current farm capex ~ pound67mMW even when producing 6
bull Unlikely to be commercial until we are gt500MW or until turbines are routine at gt12MW
bull Need to be able to produce ~50 substructures with a footprint of ~2500m2
each Cf fixed wind at one order of magnitude smaller space requirement
bull Storage post construction is an issue to be able to complete a farm in two summers
bull Integrating 12MW turbines to substructures challenges heavy lift crane vessel capabilities
bull Major component repair when constraints of farm moorings and cables are present
bull Moorings with redundancy in a farm

Concluding remarks
1 Winning in the Energy Transition needs renewables even for oil companies
2 Offshore wind growth rate is spectacular potentially reaching 35GW by 2020
3 Floating wind CAGR is expected to be even more spectacular
4 The overall technology trend is to address (a) individual to farm (b) fixed to floating (c) variable to dispatchable (d) Physical inspection to remote
5 Floating wind is maturing but not yet commercial anywhere
6 If the trends seen in fixed wind are repeated floating wind will get there with particular focus on farm scale bigger turbines dynamic cables and next generation vessels
7 But cost scale construction and operations in further deeper and harsher conditions still pose formidable challenges

Concluding remarks
1 Winning in the Energy Transition needs renewables even for oil companies
2 Offshore wind growth rate is spectacular potentially reaching 35GW by 2020
3 Floating wind CAGR is expected to be even more spectacular
4 The overall technology trend is to address (a) individual to farm (b) fixed to floating (c) variable to dispatchable (d) Physical inspection to remote
5 Floating wind is maturing but not yet commercial anywhere
6 If the trends seen in fixed wind are repeated floating wind will get there with particular focus on farm scale bigger turbines dynamic cables and next generation vessels
7 But cost scale construction and operations in further deeper and harsher conditions still pose formidable challenges

2 Offshore wind growth rate is spectacular potentially reaching 35GW by 2020
3 Floating wind CAGR is expected to be even more spectacular

5 Floating wind is maturing but not yet commercial anywhere
6 If the trends seen in fixed wind are repeated floating wind will get there with particular focus on farm scale bigger turbines dynamic cables and next generation vessels
7 But cost scale construction and operations in further deeper and harsher conditions still pose formidable challenges

Concluding remarks
1 Winning in the Energy Transition needs renewables even for oil companies
2 Offshore wind growth rate is spectacular potentially reaching 35GW by 2020
3 Floating wind CAGR is expected to be even more spectacular
4 The overall technology trend is to address (a) individual to farm (b) fixed to floating (c) variable to dispatchable (d) Physical inspection to remote
5 Floating wind is maturing but not yet commercial anywhere
6 If the trends seen in fixed wind are repeated floating wind will get there with particular focus on farm scale bigger turbines dynamic cables and next generation vessels
7 But cost scale construction and operations in further deeper and harsher conditions still pose formidable challenges

Scale construction amp operational challenges
bull Current farm capex ~ pound67mMW even when producing 6
bull Unlikely to be commercial until we are gt500MW or until turbines are routine at gt12MW
bull Need to be able to produce ~50 substructures with a footprint of ~2500m2
each Cf fixed wind at one order of magnitude smaller space requirement
bull Storage post construction is an issue to be able to complete a farm in two summers
bull Integrating 12MW turbines to substructures challenges heavy lift crane vessel capabilities
