Aluminum Ballast Tank Anodes
Available to the specified alloy, dimensions, net mass, attachment details, inspection scope and approved project drawing.
Aluminum and zinc sacrificial anodes supplied for ballast tanks, seawater compartments, newbuild vessels and drydock replacement projects.
Tank area, coating condition, ballast and empty cycles, water salinity and temperature, ventilation, mounting and hydrogen-management requirements must be reviewed in the approved CP design.

Ballast tanks alternate between wet, dry and partially filled conditions, and their coating condition changes during service. Anode quantity, alloy, mass, location and mounting therefore require an approved calculation using tank area, coating breakdown, water conditions, operating cycle, current demand, design life and applicable vessel or class requirements.
Final construction follows the approved drawing, alloy specification, mass, attachment and quality plan.

Use project-specific values. A generic catalogue value is not a substitute for the approved cathodic-protection calculation or purchase specification.
| Tank data | Tank type, count, wetted surface area, internal geometry, access and location. |
|---|---|
| Coating condition | Coating system, age, breakdown factor and repair or newbuild status. |
| Operating cycle | Ballast frequency, fill duration, empty periods, salinity and temperature range. |
| Anode | Specified aluminum or zinc alloy, shape, net mass, dimensions and quantity. |
| Mounting and safety | Weld-on or bolt-on details, insert, clearance, paint interface, ventilation and hydrogen review. |
| Documents | Approved layout, alloy and inspection records, marking, packing, ITP and class documents by order scope. |
Application labels help route the inquiry; the final anode selection still requires engineering inputs.
Manufacturing review should confirm alloy charge control, mould and core arrangement, insert preparation, casting condition, dimensions, net mass, electrical continuity, marking and packing.
Inspection and document scope must be agreed in the purchase order. Any potential, capacity, efficiency or service-life statement should identify the governing test or calculation conditions.
Provide tank count and surface area, coating system and breakdown, water salinity and temperature, ballast cycle, approved current demand, alloy and model, net mass, mounting layout, target life, vessel and class details, quantity and delivery date.
HELE reviews manufacturability and supply scope. Final cathodic-protection design responsibility must be defined by the project parties.
