Vessel Ballasting

Ballasting or de-ballasting is the process of taking in or discharging seawater from a vessel to maintain its trim, stability, and structural integrity, whether at port or at sea. Ballast water is stored in dedicated ballast tanks, which are equipped with piping systems and high-capacity pumps to carry out the operation efficiently.

Ontech’s purpose-built ballasting pumps are designed to optimise performance, improve operational efficiency, and ensure safe and reliable handling of ballast water
