The IMO regulation

• September 2013, IMO accepted to make container weight verification

mandatory.

• November 2014, IMO announced the adoption of the legislation into the

SOLAS regulations.

• 1 st of July 2016, the amendment will go into force.

The IMO regulation

The IMO regulation states that:

“The responsibility for obtaining and documenting the verified gross mass of

a packed container lies with 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”.

‣ « 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 ».

The IMO regulation

The SOLAS regulation prescribes two methods by which the shipper may obtain the verified

gross mass of a packed container:

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 .

Energy & Data Transmission Systems

The IMO regulation

Some main points:….

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.

11


Energy & Data Transmission Systems

The IMO regulation

This regulation is not new. It re-instates the existing rule which

obliges the shippers to provide the correct container weight!

What is new is that containers are not allowed to be loaded

onto vessels any more unless the weights are verified!

12


Energy & Data Transmission Systems

The IMO regulation

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.

13


Energy & Data Transmission Systems

The IMO regulation

For terminals to consider when weighing containers:….

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?

14


Energy & Data Transmission Systems

The IMO regulation

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.

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

weighing fee!

15


Energy & Data Transmission Systems

The IMO regulation

What if the regulation is not followed?

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.

16

The IMO regulation

Weighing of containers can be a lucrative business for terminals!

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.-

Why shipping lines have an interest in

knowing the exact container weight….

• 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).

‣ Conclusion: There is a high interest and benefit for shipping

lines to know the exact container weight!

Where to weigh containers?

Weighing containers with weigh bridges at the

gate entry can be cumbersome if the trucks

arrive with 2x20ft containers.

Where to weigh containers?

20

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.

Where to weigh containers?

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:….

This is the moment when hoist and trolley speeds

are constant during a loading cycle.

‣ Calculating the average load

from several load cycles

provides an accurate stabilized

container weight.

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.
