ICHCA International <strong>Safe</strong>ty Panel Briefing Pamphlet No 30<br />
11.8.5.3 Pictures 55 and 56 show two designs <strong>of</strong> bottom corner fitting / bottom rail<br />
connection but others can be seen in the preceding sections. There is a<br />
serious risk <strong>of</strong> failure if tank containers are stacked using the bottom rail.<br />
12 Stowage on ships<br />
Picture 55 Picture 56<br />
12.1 With a few notable exceptions the stowage <strong>of</strong> tank containers on board ships is<br />
no different than the stowage <strong>of</strong> any other container. Like all containers,<br />
consideration should be given to the gross mass <strong>of</strong> the tank container and its<br />
impact in any given stowage location, on the stability <strong>of</strong> the ship.<br />
Note: The gross weight <strong>of</strong> tank containers is <strong>of</strong>ten rated higher than the<br />
majority <strong>of</strong> other containers for example up to 36,000 kg. The actual<br />
value will be shown in box 19 <strong>of</strong> the Dangerous or Non Regulated<br />
Goods Note (see Annex 4, Figures A4.2 and A4.3).<br />
12.2 Allowable Stacking Weight<br />
12.2.1 The allowable stacking weight represents the maximum superimposed load<br />
that any container can be subjected to and is<br />
<strong>of</strong>ten referred to as the stacking capability or<br />
stack height (when converted to a number <strong>of</strong><br />
containers). The allowable stacking weight /<br />
superimposed weight should be entered onto<br />
The Dangerous or Non Regulated Goods Note<br />
(see Annex 4 Figures A4.2 and A4.3) in box 18c.<br />
12.2.2 The stacking capability <strong>of</strong> a tank container can<br />
also be found on the <strong>Safe</strong>ty Approval Plate fitted<br />
on the rear <strong>of</strong> the container and generally forms<br />
part <strong>of</strong> a larger plate as arrowed in Picture 57.<br />
12.2.3 The <strong>Safe</strong>ty Approval Plate will carry important data which is provided to<br />
assist in the safe handling <strong>of</strong> tank containers. Firstly the Maximum Gross<br />
Weight will be shown. In Picture 58 it is marked 34,000 kg and on the plate<br />
shown in Picture 59 for a different unit, it is 36,000 kg.<br />
12.2.4 The second piece<br />
<strong>of</strong> important data is<br />
the allowable<br />
stacking weight,<br />
which is shown as<br />
72,000 kg in the<br />
example (Picture<br />
58).<br />
