Conclusion

The Master or person responsible for the loading of the vessel should not depart a berth until the intact stability of the vessel has been calculated and it is confirmed that the statutory stability requirements, as included in the stability book approved by Class on behalf of the respective flag administration are complied with during all stages of the voyage. If it is not possible to comply, the Master should take whatever action is necessary in order to arrive at a condition that ensures the vessel is seaworthy throughout the voyage. Such action may include off loading cargo, ballasting the vessel or both.

It is good practice for Members to have clear written instructions for their Masters to cover such eventualities as stated above. It is also prudent for these instructions to cover the requirement for all stability issues to be adhered to and what action to take if they cannot be. Providing Masters know they have the backing of their operating company, there is less chance of errors being made and vessels putting to sea in an unseaworthy condition especially when pressure is brought to bear by shippers.

The aim of this booklet is to provide basic guidance to an important subject that is not always understood fully or clearly explained. A vessel’s stability and loading manual is the only authorised source of stability information for a vessel and the requirements therein must always be followed – this booklet is designed to help the reader understand this information.
