A1 Consult - NordPIANC 2019 5 Main functional requirements
• The ferry berth must be functional for the new HSC catamaran Ref. Fjord Line • New Fjord Cat (aluminum catamaran)
• The ferry berth must also be functional as an emergency berth for:
Ref. Fjord Line • SuperSpeed 1 & 2 • MS Norröna • MS Bergensfjord
• The above Ro-Ro ferries require a mooring dolphin west of the ferry berth for safe mooring (to be constructed later)
• Water level variations • MHW – MLW: ± 0,80 m (accessibility satisfied for walkways etc.) • HHW – LLW: +1,40 / -1,10 m (limit for traffic on linkspan)
A1 Consult - NordPIANC 2019 6 Design requirements for fendering
• Berthing of the aluminum catamaran requires a soft fender
• Berthing of the Ro-Ro ferries requires a relative hard fender
• Stand-off distance must be as small as possible ( < 2 m)
• Height of fender panel face: -0.30 m to +5.50 m
• Double contact on the fender panel is not allowed
• The fender panel shall be able to rotate on plan (to accommodate angled berthing to avoid point loads)
ref. Trelleborg • Width of fender panel to suit allowable reaction line load for the aluminum belting on the catamaran
• Fender design in accordance with BS6349-4 and PIANC WG33
A1 Consult - NordPIANC 2019 7 Fender design
• Two cones mounted back-to-back (soft cone + hard cone) • Energy absorption from both cones. Fender reaction ≤ hard cone • No double contact on the fender panel
