Innovation # 5: Bigger Construction Vessels
Bigger Ships for bigger loads
15
Innovation # 6: Ports & Logistics
Requirements for UK’s Offshore Plans:
• Develop two completely new ports
• One on either coast of the UK
• More than transport nodes
• Focal point for regional development
• Centres of excellence for R + D
• Training centres for
technologists/technicians
• New manufacturing centres
An entirely new approach to Logistics is needed
16
Innovation # 7: ICT
