Section 6: Carriage of Additional Ballast

  6.1 Under certain conditions as provided in Regulation 13(3) of Annex I of MARPOL 73/78, to which paragraphs (7) and (10) of the same Regulation refer, additional ballast may be carried. Before a decision is made to take on additional heavy weather ballast other measures such as reducing speed or altering course should always be considered.

  6.2 If additional ballast has to be taken on board this should, if possible, be carried in tanks which have been cleaned for routine sediment control or maintenance. Ballasting of dirty tanks should be avoided. The additional ballast is discharged as dirty ballast in compliance with Regulation 9 of Annex I of MARPOL 73/78 and following the procedure described in Section 7 of the Manual. The piping that will subsequently be used for discharging ballast from the dedicated clean ballast tanks may need to be flushed again by drawing some water from these tanks to the slop tank.

  6.3 In case the tanker during its ballast voyage sails through special areas no discharge of dirty ballast at sea will be possible in the area.
