This paper discusses design aspects of the guide-pile dolphin restraint system for a precast/prestressed concrete float that will serve as an end berth for the new Alaska Class Ferry (ACF) day boats at the Haines Ferry Terminal. The concrete float designed is 150 feet long, 120 feet wide, and 17.5 feet deep (45.7 by 36.6 by 5.3 m) and contains two landside transfer bridges which enable loading/unloading of the ACF. The guide-pile dolphin restraint system limits the horizontal movement of the float while accommodating tidal fluctuations of up to 30 feet (9.1 m) and heave, roll, and pitch under wave loading. The system resists wind and wave loads, accidental vessel impact loads, and potential liquefaction-induced lateral spreading from a seismic event.
