The sequential method of ballast water replacement at sea during the ship voyage is commonly used on board the ships. However, the successive emptying and filling of ballast tanks causes the occurrence of hazards to ship’s safety. The article presents the calculation results of ship roll motions, pitch motions, slamming and emergence of propeller during ballast replacement at different sea states. It has been shown at which stages of ballast replacement specific hazards arise and how they could be avoided or minimized, especially under severe weather conditions.
