A ship not having onboard a document of authorization issued in accordance with Grain Code & still want to load grain cargo may be permitted to load bulk grain but then it needs to fulfil certain criterias which is as follows:
- The total weight of the bulk grain shall not exceed one third of the deadweight of the ship;
- All filled compartments, trimmed, shall be fitted with centreline divisions extending, for the full length of such compartments, downwards from the underside of the deck or hatch covers to a distance below the deck line of at least one eighth of the maximum breadth of the compartment or 2.4 m, whichever is the greater, except that saucers constructed in accordance with Grain code may be accepted in lieu of a centreline division in and beneath a hatchway except in the case of linseed and other seeds having similar properties;
- All hatches to filled compartments, trimmed, shall be closed and covers secured in place;
- All free grain surfaces in partly filled cargo space shall be trimmed level and secured in accordance with grain code;
- Throughout the voyage the metacentric height after correction for the free surface effects of liquids in tanks shall be 0.3 m or that given by the following formula, whichever is the greater:
GMR = L B Vd (0.25 B – 0.645 × square root of Vd B)/ SF x Δ x 0.0875
L =total combined length of all full compartments (metres)
B = moulded breadth of the vessel (metres)
SF = stowage factor (cubic metres per tonne)
Vd = calculated average void depth calculated in accordance with B 1 (metres-Note:not millimetres)
D = displacement (tonnes);
- The master demonstrates to the satisfaction of the Administration or the Contracting Government of the port of loading on behalf of the Administration that the ship in its proposed loaded condition will comply with the requirements of this section.
A ship without such a document shall not load grain until the master satisfies the Administration, or the Contracting Government of the port of loading on behalf of the Administration,that the ship will comply with the requirements of the International Grain Code in its proposed loaded condition.
