On board the Vestvind, the existing anti-heeling system was replaced by a Hoppe Anti-Heeling System to meet increased demands for operational safety, precision, and ease of operation.

The main challenge was a highly complex tank configuration, consisting of three tank pairs and additional extension tanks at both ends of the vessel, resulting in a total of five tanks per side. The system is connected via a central pipe manifold with DN500 and DN350 lines. At the same time, the operational concept was deliberately designed for manual operation, with a maximum of two pumps running simultaneously and one pump in standby.

The Hoppe Anti-Heeling System was engineered specifically to match these conditions. Three frequency-controlled H300 pumps with zero-flow capability provide fast, stable, and finely adjustable heeling compensation, even under rapidly changing load conditions. The hydraulic layout ensures efficient and smooth ballast transfer between tank pairs and extension tanks, avoiding pressure surges and ensuring predictable system behavior.

A key advantage of the system is its clear and intuitive operating philosophy. Despite the complexity of the tank and piping arrangement, the system remains easy and safe to operate for the crew. Longitudinal pump piping and a well-defined separation between operating and standby pumps significantly enhance system availability while reducing the risk of operator error.

With the Hoppe Anti-Heeling System, the Vestvind now benefits from:

• significantly improved heeling stability
• optimal utilization of the installed pump equipment
• high operational reliability with reduced system complexity
• a future-proof solution for demanding tank configurations

This project demonstrates how tailor-made Hoppe system solutions deliver measurable improvements in efficiency, safety, and operability—even for highly complex vessel designs.
