NOTE To avoid damage to the GRP tank or vessel during delivery, temporary bracings should be used.

4.4 Storage

If after unloading, the GRP tank or vessel cannot immediately be installed in it's final position, it shall be stored as follows:

a) Wherever possible the GRP tank or vessel shall be stored in the design orientation i.e. vertical tank or vessel shall be stored (supported and anchored) vertically. If it is not possible to store the item in their operational orientation it may be stored otherwise with special considerations on supporting and anchoring. The use of saddles or supporting timbers with wedges may be necessary.

b) The storage area shall be level and free from protrusions or ridges to avoid point loading. The GRP vessel or tank shall be located in an area removed from vehicular traffic or suitably protected from traffic. Consideration shall be given to movements due to wind on the empty item and temporary anchors shall be provided.
