Cranes Relocation

|
|
Crane relocation requires
careful analysis of the crane structures and the behaviour of the
vessel under different sea conditions. Crane structures normally
require strengthening for journeys at sea. Lashing arrangement has
to be carefully designed to avoid any damage to the crane, which
can arise from excessive stresses encountered during the voyage
or excessive welding or heating in the lashing arrangement.

|
The fork lift method
of loading and shipping has become the most popular method of transporting
quay side container cranes. With proper understanding of the procedures
and careful planning, this method is both fast and safe, and presents
minimum disruption to the operation of the terminal.

Self Sustained Heavy
Lifting Vessels |
|
For long sea journeys,
this is the preferred way. The vessel is ballastable for Ro - Ro
operation or is equipped with heavy lift cranes for lifting the
RTGs. |
|
|
|
Tug and Barge |
|
Feasible for shorter
sea voyage up to about 6000 KM. Lashing arrangement has to be ridgid
and robust to cope with rolling, pitching motions of the barge in
the high seas. Loading and unloading is by means of roll on/roll
off or by means of floating cranes. |
|
|
|
Floating Crane |
|
Pick and carry method
, normally applicable over a short distance within the harbour. |
|
|
|
The entire relocation
exercise involves decommissioning the RTG , pre-shipping preparation,
loading, lashing, insurance survey, unloading, and re-commissioning
of the equipment. |
