Bulk cargoes other than grain: Regulation for loading, unloading and stowage
The MS (Carriage of Cargoes) Regulations 1999 (SI 1999/336) [ regulation 10 ] applies to ships loading bulk cargoes other than grain. In regulation 10 terminal representative means an individual who represents the terminal or other facility where the ship is loading or unloading and who has responsibility for operations conducted by that terminal or facility with regard to the particular ship.
Regulation 10(2) provides that to enable the master to prevent excessive stresses in the ships structure, it will be the duty of the owner to ensure the ship has a Cargo Loading Manual, which must be written in a language with which the ships officers responsible for cargo operations are familiar. If this language is not English, the ship must also have a manual in English. The manual may consist of one or more booklets and must, as a minimum, include:
stability data, to the extent required by regulation 32 of the Merchant Shipping (Load Line) Regulations 1998;
ballasting and deballasting rates and capacities;
maximum allowable load per unit surface area of the tank top plating;
maximum allowable load per hold;
general loading and unloading instructions with regard to the strength of the ships structure including any limitations on the most adverse operating conditions during loading, unloading, ballasting operations and the voyage;
any special restrictions such as limitations on the most adverse operating conditions imposed by the Administration or organization recognised by it, if applicable; and
where strength calculations are required, maximum permissible forces and moments on the ships hull during loading, unloading and the voyage.
Under regulation 10(3), before a solid bulk cargo is loaded or unloaded, the master and the terminal representative (who is defined in regulation 10(1)(a) as an individual who represents the terminal or other facility where the ship is loading or unloading and who has responsibility for operations conducted by that terminal or facility with regard to the particular ship) must agree on a plan (i.e. a loading plan or unloading plan) which:
will ensure that the permissible forces and moments on the ship are not exceeded during loading or unloading, and
will include the sequence, quantity and rate of loading or unloading, taking into consideration the intended speed of loading or unloading, intended number of pours and the deballasting or ballasting capability of the ship. The plan and any subsequent amendments to it must be lodged with the appropriate authority of the port State.
The master must ensure that bulk cargoes are loaded and trimmed reasonably level, as necessary, to the boundaries of the cargo space so as to minimise the risk of shifting and to ensure that adequate stability will be maintained throughout the voyage (regulation 10(4)).
Under regulation 10(5), the master must ensure that: when bulk cargoes are carried in tween-decks, the hatchways of such tween-decks are closed in those cases where the loading information indicates an unacceptable level of stress of the bottom structure if the hatchways are left open (regulation 10(5)(a));
the cargo is trimmed reasonably level and either extends from side to side or is secured by additional longitudinal divisions of sufficient strength (regulation 10(5)(b)); and
the safe load-carrying capacity of the tween-decks is observed to ensure that the deck -structure is not overloaded (regulation 10(5)(c)).
The master and terminal representative must ensure that loading and unloading operations are conducted in accordance with the agreed loading or unloading plan (regulation 10(6)).
If during loading or unloading any of the above-mentioned limits of the ship (e.g. maximum allowable load per hold) are exceeded or are likely to become so if the loading or unloading continues, the master has the right to suspend operations, and if he does so he must notify accordingly the appropriate authority of the port State with which the plan has been lodged (regulation 10(7)(a)). (For the meaning of appropriate authority, see above.) In this event both the master and the terminal representative must ensure that corrective action is taken (regulation 10(7)(b)).
When unloading cargo, the master and terminal representative must ensure that the unloading method does not damage the ships structure (regulation 10(7)(c)).
The master must ensure that ships personnel continuously monitor cargo operations (regulation 10(8)(a)).
Where possible, the ships draught must be checked regularly during loading or unloading to confirm the tonnage figures supplied (regulation 10(8)(b)).
Each draught and tonnage observation must be recorded in a cargo log book (regulation 10(8)(c).
If significant deviations from the agreed loading or unloading plan are detected, cargo or ballast operations or both must be adjusted to ensure that the deviations are corrected (regulation 10(8)(d).

Operation of sea going bulk carriers involved numerous hazards . Careful planning and exercising due caution for all critical shipboard matters are important . This site is a quick reference to international shipping community with guidance and information on the loading and discharging of modern bulk carriers so as to remain within the limitations as specified by the classification society.
It is vital to reduce the likelihood of over-stressing the ship's structure and also complying with all essential safety measures for a safe passage at sea. Our detail pages contain various bulk carrier related topics that might be useful for people working on board and those who working ashore in the terminal. For any remarks please Contact us
