LESSONS LEARNED
design basis:Importance detailed site investigation ‘money well spent’=> for example -> Detected objects during investigation (width 50m, 11 lines) 165 objects detected with electromagnetic survey, 20 objects detected with side scan sonar -> local adjustments cable route + 60 investigated locations (± 25 objects were removed)!
design: Involve contractor at an early stage in design & build phase
construction: 1 lead maritime partner “1 admiral at sea”=> owner of the key maritime department
contracting:Reduce interfaces; the more interfaces, the more potential risks for owner
financing: Transparent communication to lender & lender’s engineer
permits & supervision:Early involvement of authorities; 1 single point of contact within owner’s organisation
O&M: Accessibility=>availability (e.g. service crane at each windturbine).
