3103F.10.3 Base Bolts
Base bolts are subjected to both shear and uplift. Forces on bolts shall be determined using the following factors:
- Height of load application on bitts or bollards.
- Actual vertical angles of mooring lines for the highest and lowest tide and vessel draft conditions, for all sizes of vessels at each particular berth.
- Actual horizontal angles from the mooring line configurations, for all vessel sizes and positions at each particular berth.
- Simultaneous loads from more than one vessel.
For existing MOTs, the deteriorated condition of the base bolts and supporting members shall be considered in determining the capacity of the fitting.
