How to Take Care of Cargo on Container Ships at Sea?
On container ships, cargo is carried in standardized
containers, which are placed one over the other and
secured using lashing.
While at sea, the ship is subjected to heavy rolling
5 and pitching, which can not only disturb the cargo but
also upset the stability of the ship. Parametric rolling
– a unique phenomenon on container ships, must be
carefully dealt with in order to ensure safety of cargo
containers at sea.
10___Keeping a watch on the loaded cargo containers
when the container ship is sailing is as equally
important as preparing a container ship for loading
cargo. Also, officers must know all the important
equipment tools which are used to handle cargo on
15 container ships.
The following important points must be considered
for taking care of cargo containers while at sea:
Check lashing
Proper container lashing is one of the most
20 important aspects of securing cargo safely on the
ships. Every officer in charge of cargo loading and
unloading must know and understand the important
points for safe container lashing.
Moreover, when the ship is sailing, lashing
25 must be checked at least once a day and tightened
whenever necessary.
If the ship is about to enter rough sea or in case of
heavy weather, lashing should be frequently checked
and additional lashing must be provided wherever
30 required.
Checking containers with dangerous goods
Cargo containers carrying dangerous goods must
be checked at regular intervals of time, especially in
bad weather. Dangerous goods containers must be
35 frequently checked for leakages or damages while the
ship is sailing.
Checking reefer containers
Reefer containers (refrigerated containers) must
also be checked and monitored at least twice daily for
40 proper functioning. Frequent monitoring is required in
case of special reefer cargo containers or containers
which are suspected to malfunctioning.
Avoid wet damage of cargo
Adverse weather condition might result into
45 damage of cargo because of leakages from water and
oil systems. Such kind of damage to container ships
is known as wet damage. Water from rains might also
get accumulated inside the cargo hold and damage
the cargo in lower tier containers in the cargo hold.
50___Regular sounding of cargo hold bilges is of utmost
importance for early detection of problems related to
water or oil ingress in cargo holds.
Bilges, the bottom inside part of a ship where
dirty water collects, must be checked once a day in
55 normal weather condition and at regular intervals of
time in rough weather. When the ship is at port, cargo
hold bilges must be drained into holding tanks.
Regular rounds of the cargo deck compartment
must be made to check the condition of lashing and
60 cargo containers.
Sometimes, it might so occur that in spite of taking
all the necessary precautions, damage to cargo or the
ship’s hull would take place. In such cases, the master
of the ship must take the necessary precautions to
65 minimize the damage. He should also report the same
to the company and make necessary entries in the
ship’s log book.
A master’s report on the damages sustained
must also be made along with a sea protest which is
70 to be produced at the next port.
