The
catastrophic earthquake did much damage on harbor
loading/unloading equipments such
as gantry crane.
Lessons
from the damages of
Port
of Kobe
by Great Hanshin Earthquake in 1995 led
nationwide ports to anti-earthquake
reinforcement promotion for wharf, crane, and so on.
As a result, wharf damages this time were
relatively smaller than those by Great Hanshin Earthquake.
However, floods and floating wreckages by tsunamis after the
earthquake in March caused huge
damages on loading equipments and sheds .
Water
damages of electrical systems like transforming equipments
take a few months to get fixed, as
they are basically order products. Even if damages of port
facilities such as wharves are not terrible, out of use
loading equipments jeopardize logistics and industrial
functions of harbors for a long time,
which affects not only economic recovery process of the
disaster-stricken areas but the whole
country.
The container terminal of
Port
of Sendai-Shiogama
got heavy damages particularly. We
believe that it was the very first time for such a
large-scale container terminal to get damaged by tsunami in
the world. The feature of this month shows efforts to
achieve possible earliest restoration of the Sendai-Shiogama
container terminal and loading machines’
preparation for natural disasters such as
earthquake,tsunami,storm and so forth.
