Abstract
Between December 1982 and January 1984 the berthing impacts o~
50 ore carriers were monitored at the Saldanha Bay ore-jetty.
The actual displacement o~ the monitored vessels ranged
between 60 and 263 kilotonnes. Only 507. o~ the monitoring runs
yielded complete sets o~ data.
Approach velocities recorded were high and the design limits
were exceeded several times resulting in ~enders being
de~lated on ~our occasions.
The added mass coe~~icient ~or each impact was calculated. The
actual values o~ C" varied between 1 and 7. This agrees with
values ~ound in literature.
Some o~ the\high values could be attributed to inaccuracies in
the measurement techniques.
From the values obtained ~or added mass it seems that the
value used in the design was very low and that a unitary value
~or CH is not very satisfactory.
