Anti-Vibration / Driveline Yacht / Superyacht Applications

Aquadrive Anti-Vibration System

Aquadrive is a proven refit solution designed to reduce driveline vibration in yachts and superyachts. The system aims to manage loads on the engine and shaft line, reduce noise/vibration transmission, and help protect the gearbox and shaft line. With proper engineering planning, it can provide improved comfort, extended component life, and lower maintenance costs.

Product Overview

In traditional shaft arrangements, engine thrust and vibrations can be undesirably transmitted to the gearbox, shaft line, and vessel structure. The Aquadrive approach aims to isolate thrust forces in the driveline and manage shaft line misalignment with greater tolerance. As a result, guest/crew comfort can be improved while critical drivetrain components may be subjected to less stress.

Reducing Noise and Vibration Transmission

Reducing structural noise and vibration transmission improves cabin comfort and cruising quality.

Gearbox and Shaft Line Protection

Isolating thrust forces can help reduce loads on the gearbox and shaft line.

Practical Application for Refit Projects

For time-critical revisions, a fast and non-invasive installation approach can be preferred with proper planning.

How Does It Work?

The Aquadrive system approach is based on two key principles: management of thrust forces and tolerance of misalignment. The thrust bearing safely transfers thrust forces in the driveline to the hull structure, while the CV shaft connection can provide a more flexible operating range for angular and axial misalignments. This configuration aims to reduce the transmission of vibrations into the structure.

Component Function
Thrust Bearing Controls the thrust force and transfers it to the hull structure from the appropriate point; helps reduce thrust load on the gearbox.
CV Shaft Aims to reduce vibration transmission by managing angular/axial shaft line misalignments with greater tolerance.
Gearbox Adapter Plate / Connections Creates suitable mounting and geometry with the existing drivetrain components; facilitates integration in refit projects.
Flexible Engine Mounts Optional Vibration isolation can be supported with suitable mount selection; system performance should be evaluated as a whole.

Key Benefits

  • Improved comfort: Vibration and noise levels felt in cabins can be reduced.
  • Protection: The gearbox and shaft line may be less affected by thrust forces.
  • Longer service life: Lower stress on drivetrain components can help reduce maintenance requirements.
  • Refit compatibility: A solution approach that can be applied without requiring major structural modifications.
  • Maintenance cost: Total cost of ownership can be reduced through proper alignment and load management.

Final benefits may vary depending on the vessel hull type, engine/gearbox selection, shaft geometry, and installation quality. For the most accurate result, a project-based technical assessment is recommended.

Application Areas

The Aquadrive anti-vibration system stands out especially in refit projects and vessels with high comfort expectations. A suitable solution is configured after reviewing the existing shaft line architecture, engine mounts, and gearbox connection details.

  • Superyacht and motor yacht projects: Low noise/vibration targets for guest comfort.
  • Refit & revision: Practical integration approach for time-critical schedules.
  • Misalignment issues: Shaft lines where angular/axial misalignments need to be managed with greater tolerance.
  • Drivetrain protection: Applications where the goal is to reduce loads that stress the gearbox/shaft line.

Frequently Asked Questions

Does the Aquadrive system deliver the same result on every vessel?
No. The result is directly related to the hull structure, shaft line geometry, engine/gearbox selection, and installation quality. Therefore, a project-based technical assessment is required.
Does installation require major structural modifications?
In most refit scenarios, the goal is to achieve integration with minimum intervention. However, the final installation plan is determined according to the vessel’s existing infrastructure.
What information do I need for a quick quotation?
Vessel length, engine/gearbox information, shaft diameter, and a short description of the current issue vibration/noise are generally sufficient for initial matching. Adding photos/videos speeds up the process.
