Checklist to show stability, hull strength, draft, trim, suitability of cargo for a bulk carrier

The conditions of stability, hull strength, draft and trim of bulk carriers at sea and on arrival / departure at / from port and during loading / unloading cargo, bunkering and water ballast exchange, should be worked out, ensuring safety of the vessel. Safety of the cargo vessel depends on proper GM, stress calculation and other factors as being within appropriate Limits.

During stowage the first consideration must be given to safety, i.e. the cargo must be stowed so that the ship will be stable and seaworthy, and it must be secured in such a manner that it cannot shift if the vessel encounters bad weather. The type of vessel, the cubic capacity of her compartments destined for the cargo and the appliances on board or on shore for loading or discharging, as well as the nature of the cargo, affect the question of how to stow the cargo in the best possible manner.



The ship must be made neither stiff nor too tender. The next consideration is for the safety of the cargo itself: it must not be damaged by shifting; certain commodities become easily tainted by others, water might find its way into the hold and condensation or sweating must be prevented. Valuable cargo may be stolen or broached.

Finally, the Chief Officer must bear in mind the various destinations of the goods the ship carries, and arrange things, as far as he can, to see that the cargo for a certain place can be lifted out without disturbing the other cargo. The Chief Officer must watch closely the ship's stability (i.e. what the ship's trim is or how she is sitting).

Since a ship is supported by fluid pressure she will incline in any direction according to the position of the weights placed on her. The trim, therefore, is the angle that a ship is making, fore and aft, with the water.

The levels are read by numbers painted on the ship's stem and stem. These are called draught marks. Another word is heel. This means a list or inclination from one side to another, caused by loading. The Chief Officer must watch the load lines. They are welded or punched on and then painted.


Following are the check item confirming stability and hull strength of cargo ship:



Check items

Following are the guideline to check suitability of loading/ unloading solid bulk cargo

i) Cargo holds and hatch openings are suitable for cargo operations

ii) Holds are clearly numbered on hatch covers/ coamings

iii) Hatch covers, hatch operating systems and safety devices are in good operational condition

iv) List indication lights, if fitted, have been tested prior to arrival and are operational

v) If applicable, loading instrument is certified and operational

vi) Propulsion/auxiliary machinery is in good operational order

vii) Mooring equipment is in good functional order

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
