Suitability of ships and terminals for handling solid bulk cargo

All ships nominated for loading should hold the appropriate valid statutory certification including, if required, the document of compliance for ships carrying solid dangerous goods in bulk. It is recommended that the period of validity of the ship’s certificates be sufficient to remain valid during loading, voyage and unloading times, plus a reserve to allow for delays in berthing, inclement weather or both.

The shipowner, manager or operator, when offering a ship for a particular cargo or service, should ensure that the ship:



It is essential that a ship selected to transport a solid bulk cargo be suitable for its intended purpose taking into account the terminals at which it will load or unload.

The charterer and shipper when accepting a ship for a particular cargo or service should ensure that the ship:



Ships requirements

Ships nominated for bulk loading should be suitable for the intended cargo. Suitable ships should be:

It is recommended that all ships which are required to carry out stress calculations should have on board an approved loading instrument for the rapid calculation of such stresses.

All propulsion and auxiliary machinery should be in good functional order. Deck equipment related to mooring and berthing operations, including anchors, cables, mooring lines, hawsers and winches, should be operable and in good order and condition.


Applicable to ships constructed on or after 1 September 1984 :

All hatches, hatch operating systems and safety devices should be in good functional order, and used only for their intended purpose.

List indication lights, if fitted, should be tested prior to loading or unloading and proved operational.

Ship’s own cargo handling equipment should be properly certificated and maintained, and used only under the general supervision of suitably qualified ship’s personnel.


Terminals requirements

Terminal operators should ensure that they only accept ships that can safely berth alongside their installation, taking into consideration issues such as:

Terminal equipment should be properly certificated and maintained in accordance with the relevant national regulations and/or standards, and only operated by duly quali?ed and, if appropriate, certificated personnel.

Where automatic weighing equipment is provided, this should be calibrated at regular intervals.

Terminal personnel should be trained in all aspects of safe loading and unloading of bulk carriers, commensurate with their responsibilities.

The training should be designed to provide familiarity with the general hazards of loading, unloading and carriage of bulk cargoes and the adverse effect improper cargo handling operations may have on the safety of the ship.

Terminal operators should ensure that personnel involved in the loading and unloading operations are duly rested to avoid fatigue.

Wooden hatch covers, consisting of beams and boards over the opening and covered with tarpaulins, were once used but are no longer fitted. Steel hatch covers, comprising a number of linked steel covers, are now fitted universally. Various designs exist for particular applications, but most offer simple and quick opening and closing, which speed up the cargo handling operation..
