Based on this investigation by Germanischer Lloyd, maximum sensible weight for safe
unrestricted transportation by sea can only be 15 t. According to the above-mentioned
investigation, safe restricted transportation of Flexitanks by sea (excluding the ocean regions
8, 9, 15 and 16) is only possible up to a maximum weight of 18 t. These values only apply to
vessels of a length greater than 170 m.
This investigation has shown that the stability of the vessel and the stowage position, either
fore/midships/aft or on deck/below deck significantly affect the lateral acceleration forces
during a voyage. It is not possible to have any influence on the stability of a vessel from the
outside. This depends on the amount of cargo/ballast the vessel is carrying and on its
construction. The stowage position, either on deck/below deck or fore/midships/aft can only
be influenced by applying restrictions. Even if the carriers were to accept such restrictions,
they would involve additional costs. Our experience suggests that Flexitank users are
unlikely to be willing to accept such costs.
If Flexitanks weighing more than 15 or 18 t are used and are not transported subject to the
restrictions above, the parameters underpinning this investigation (stowage position, length
of the vessel, and possibly stability and restricted transportation) should nevertheless be
observed. If this is not done, it is not possible to transport Flexitanks safely by sea. If
Flexitanks are to be transported on smaller vessels without the restrictions with respect to the
stowage position, they can only be safely carried up to the weights shown in Figure 9.
