Ballast tanks control a ship's stability, trim, and draft by taking in or discharging water. This adjusts the vessel's weight distribution and center of gravity, ensuring safe navigation under different loading conditions.
Ballast tanks are typically constructed from marine-grade steel and protected with anti-corrosion coatings. The specific material grade and coating system must be confirmed with the manufacturer for the intended application.
Key parameters include design pressure (0.5–2.5 MPa), test pressure (1.5–3.8 MPa), capacity (100–5000 m³), filling/discharge rate (500–5000 m³/h), corrosion allowance (1.0–3.0 mm), plate thickness (10–25 mm), operating temperature (-10–50 °C), coating system (2–3 coats), cathodic protection potential (-850 to -1100 mV), and weight (50–500 t). These are reference ranges and must be verified for each model.
Regular inspections, coating maintenance, and checks of the cathodic protection system are essential. Hydrostatic testing at 1.5 times the design pressure is performed to verify structural integrity. All maintenance and testing should follow the manufacturer's guidelines and relevant standards.
