• September 2013, IMO accepted to make container weight verification
mandatory.
• November 2014, IMO announced the adoption of the legislation into the
SOLAS regulations.
• 1st of July 2016, the amendment will go into force.
The IMO regulation

« If the shipper does not declare the correct container weight, then a
third party, for example the terminal, shall weigh the container and
charge the shipper ».
“A container packed with packages and cargo items should not be loaded
onto a ship to which the SOLAS regulations apply unless the master or his
representative and the terminal representative have obtained, in advance of
vessel loading, the verified actual gross mass of the container”.
“The responsibility for obtaining and documenting the verified gross mass of
a packed container lies with the shipper”.
The IMO regulation
The IMO regulation states that:

Method No.1:
After the container is loaded and sealed, the shipper may weigh, or have arranged that a
third party weighs the container.
Method No.2:
The shipper may weigh all packages and cargo items, including the weights of pallets and
other packing and securing material to be packed in the container, and add the tare weight
of the container to the sum of the single masses using a certified method .
The IMO regulation
The SOLAS regulation prescribes two methods by which the shipper may obtain the verified
gross mass of a packed container:

1. Weighing systems need to be certified and calibrated. No specific requirements
are given by IMO. The law of each country will apply.
2. Accuracy: No details are given. The law of each country will apply.
3. Empty containers will not have to be weight verified.
4. Transshipped containers will not have to be weight verified.
Some main points:….

What is new is that containers are not allowed to be loaded
onto vessels any more unless the weights are verified!
This regulation is not new. It re-instates the existing rule which
obliges the shippers to provide the correct container weight!

The objective of IMO is to weigh containers at the beginning of
the supply chain which is at the point of loading the containers.
However, this is not always possible.
The most practical place is to weigh containers in the terminal
as they arrive by road or by rail.

1. The terminal becomes legally responsible when weighing containers.
2. Choose a weighing solution which does not disrupt the work flow.
3. Develop an administrative system to update container weights in the manifest , notify shipping lines,
shippers and customs and update the stowing plan.
4. How to charge for the weighing service. (e.g. add a « weighing fee » ).
5. Will additional space be required to store containers which are not conform?
6. Does your country require import containers to be weight verified as well?
For terminals to consider when weighing containers:….

7. Transshipped containers do not need to be weight verified, but you may want to weigh them anyway.
(It might be easier than to check the authentification of the weighing certificate ).
8. What to do if a trans-shipped container is found overweight.
9. What to do if an imported container is found within the weight limit, but it is eccentrically loaded and it will
overload a truck axle on the road.
For terminals to consider when weighing containers:….

This is why also the administrative costs and risks have to be taken into account when calculating the
weighing fee!

Containers which will be loaded onto vessels after 1 July 2016 and which are not weight verified
may not be covered by the shipping line’s maritime insurance . The vessel may not be considered
sea worthy.
The shipping line will therefore have a vital interest to load only containers which are weight
verified.
What if the regulation is not followed?

Business case assumptions:
Number of RTGs: 20 cranes
Number of TEUs: 1 million TEU
Number of containers to be weighed: 500’000 containers
Equipment investment to provide weighing service: $ 300’000.-
Charge by terminal to shippers to weigh 1 container: $ 10.-
ROI: 1 month
Cost of weighing one container: € 0,22 / Container
Net annual revenue: € 5’480’000.-
Weighing of containers can be a lucrative business for terminals!

• The center of gravity of the load in a vessel needs to be in the
center and as low as possible in the vessel.
• Vessels are typically loaded only up to 90% of its capacities.
• The actual gross weight is often higher than declared.
• Water is used to balance the vessel if the load is not
balanced.
• Fuel consumption of a vessel is a very high proportion of the
total sailing cost. (A 8’000 TEU vessel consumes up to $ 4
million worth of fuel for a 25 days voyage).
Why shipping lines have an interest in knowing the exact container weight….
Conclusion: There is a high interest and benefit for shipping
lines to know the exact container weight!

Weighing containers with weigh bridges at the
gate entry can be cumbersome if the trucks
arrive with 2x20ft containers.

Weighing with STS cranes is too late to update
the stowing plan.
Some South American countries demand
containers to be weighed as they are being off
loaded.

Weighing in the stacking yard with twistlocks is
the best option. All containers are passing
through the stacking yard, even transhsipped
containers. There is enough time to update the
stowing plan before loading onto vessels.

o An innovative
development uses the
spreader twistlocks to weigh
containers and to improve
safety in container handling.
o Using the spreader
twistlocks allows to weigh
each container individually
in twinlift spreader
applications.

Main advantages of LASSTEC
o On-the-go weighing. No need to interrupt the crane
loading cycle.
o No need for infrastructure changes in the terminal.
o Weighing of each container individually in twinlift
applications.
o Weighing accuracy per container over the full
measuring range: +/- 1%.
o Several operational safety functions in addition to
weighing of containers.
o Load cycles and data logging functionalities.
o Easy to install on existing spreaders.
o The system fits in every type and brand of spreader.

LASSTEC Weight Stabilizing Principle
When to capture the stabilized container weight during a loading
cycle:….
Calculating the average load
from several load cycles
provides an accurate stabilized
container weight.
This is the moment when hoist and trolley speeds
are constant during a loading cycle.

Publications on container weighing
PEMA – Ports Equipment
Manufacturer Association
has issued a publication on
container weighing.
This publication describes different
options to weigh containers in
terminals. The publication can be downloaded from
the Internet under www.pema.org
