BALLAST WATER MANAGEMENT — FROM TANK TO SEA

BALLAST WATER MANAGEMENT — FROM TANK TO SEA

Ballast water is essential for ship stability, trim and safe operation, but it can also transport marine organisms between different regions. Proper ballast water management helps reduce the transfer of potentially harmful aquatic organisms and supports protection of the marine environment.

This infographic covers:

Ballast Water System — Sea chest, ballast pump, ballast lines and ballast tanks
Ballast Water Management System (BWMS) — Treatment equipment used to manage ballast water
Ballast Operations — Intake, treatment/management, storage and discharge
Ballast Water Exchange — An established management method when applicable
Documentation — Ballast Water Management Plan, Ballast Water Record Book and relevant documents
Operational Practices — Proper operation, maintenance, record keeping and compliance
Environmental Protection — Responsible ballast management helps protect marine ecosystems

A useful educational resource for deck officers, marine engineers, cadets, seafarers and maritime students.

️ Important: Ballast water requirements depend on the applicable regulations, vessel, voyage and port conditions. Always follow the vessel’s approved Ballast Water Management Plan, BWMS operating instructions and applicable requirements.
