K12 - Ship impact, Global assessment
The global response of the bridge due to ship impact has been studied in this report. The main focus is impacts between ship deckhouse and girder and between ship bulb and pontoon. Girder impacts all along the bridge length have been considered, orthogonal to the bridge girder from both directions. Pontoon impacts have been considered on all three pontoon types, at selected characteristic locations along the bridge. Three impacts are considered; head on (0-degrees) and centric and eccentric side impacts (90-degrees). Pontoon impact from a sideway drifting ship and submarine impact has also been discussed. Post impact the bridge must withstand 100-years environmental conditions.
