Notes: The displacement of floating drydocks and their maximum draft when
submerged may be obtained from Ships Characteristics Database,
1
Berthing depths are usually measured from extreme low water (ELW).
2
Without outriggers.
3
Berthing depth required is equal to maximum draft of floating drydocks in
submerged condition plus 0.6 m (2 ft.) In case of excessive silting (0.3 m (1 ft) per
year or over), more than 0.6 m (2 ft) should be added.
