Terminal duties while unloading solid bulk cargo- Bulk carrier guide

The terminal representative should follow the agreed unloading plan and should consult with the ships officer if there is a need to amend the plan. Unloading from holds should be such as to minimize undue listing, twisting, stressing as a result of cargo handling. The ship is to be kept upright or, if a list is required for operational reasons, it is to be kept as small as possible.

The cargo should be removed in a methodical pattern across the hold so that any listing to one side and then the other is kept small and is constantly being corrected. The unloading of the port side closely matches that of the starboard side in the same hold, to avoid twisting the ship. Where grab operations are carried out in automatic or semi-automatic mode the unloader operator should:

i) Ensure the limits are set correctly for every hold.
ii) That both ship and unloader are monitored constantly for any deviation from these limits.
iii) That the pattern followed by the grab is systematic and even across the hold.

Unloading rates and sequences should not be altered by the terminal unless by prior consultation and agreement between the ship and the terminal representative.

Where there is significant and unavoidable delays to the unloading, or a reduction in the expected rates due to breakdowns or problems with the terminal materials handling system, the master should be informed and the plan amended as necessary.

The terminal representative should advise the ship when unloading is considered to be completed from each hold.

The terminal should make every effort to avoid damage to the ship when using unloading or hold cleaning equipment. If damage does occur, it should be reported to the ship and, if necessary, repaired. If the damage could impair the structural capability or watertight integrity of the hull, or the ship's essential engineering systems, the Administration or an organization recognized by it and the appropriate authority of the port State should be informed, so that they can decide whether immediate repair is necessary or whether it can be deferred.

In either case, the action taken, whether to carry out the repair or defer it, should be to the satisfaction of the Administration or an organization recognized by it and the appropriate authority of the port State. Where immediate repair is considered necessary, it should be carried out to the satisfaction of the master before the ship leaves the port.

The ships officer should inspect each hold as soon as possible after the completion of unloading of cargo from the hold. Any damage found should be reported to the terminal representative immediately. The terminal representative should monitor the weather conditions and provide the master with the forecast of any local adverse weather condition.

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.
