Updates & Upgrades

Upgrading from an FCM to an ECM provides more precise control of the fin movement, which directly improves system efficiency and reduces wear on both the fin bearings. Beyond smoother operation, the ECM offers advanced connectivity and diagnostic capabilities that significantly enhance troubleshooting and maintenance.

Through the ECM interface, local alarms and system alerts can be viewed in real time, allowing technicians to identify and address issues quickly. If a fault condition is detected that could compromise safety such as excessive fin angle, loss of position feedback, or communication failure with the hull unit the ECM automatically triggers protective control logic. This includes isolating the affected system to prevent further damage.

A sea trial is required following installation to induce a controlled roll and properly calibrate operational parameters, ensuring the system performs optimally under real conditions.

This “Fin Wagging Device” – This is a handheld stabilizer fin movement controller that allows the engineer to grease the hull unit and tapered pin adjustment safely by moving the fin locally in a controlled manner. It ensures the movement of tiller is even during maintenance. There are four pre-set fin speeds and an intuitive interface.

The auto greaser is a dedicated pump that automatically lubricates the system, significantly reducing manual maintenance requirements and ensuring consistent performance. Unlike manual greasing, the auto greaser operates while the system is running, maintaining precise lubrication intervals that prevent both under- and over-greasing. This continuous, measured delivery helps extend component life, reduce bearing wear, and improve overall system reliability.

A minor adjustment to the control box will always be necessary to properly integrate the auto greaser with the existing system controls.

Quantum offers many solutions to minimize onboard noise and vibration:

• Anti-vibration mounts and footings for HPU unit
• Add hydraulic suppressors/dampeners
• Add sound shields to the HPU unit

For yachting applications, Quantum strongly recommends the use of tapered pins. This is a precision-engineered design that of the cylinder pins to eliminate any play within the cylinder bearings. This upgrade removes knocking noises and improves overall system stability and performance. During scheduled service visits, this upgrade is offered to bring any stabilizer system up to current Quantum standards.

For vessels equipped with one-way acting centering cylinders that reinforce the system during shutdown and astern maneuvering, an upgrade is available to actively retract the centering cylinders during stabilizer operation. This enhancement eliminates the need for the fins to push the cylinders back into position, resulting in a quieter, smoother, and safer system with reduced mechanical stress and improved overall performance.

Installing nitrogen gauges on the accumulators provides a clear and immediate indication of system pressure, improving both safety and troubleshooting. During operation, the gauges display real-time hydraulic pressure levels, allowing technicians to verify proper system function. When the system is shut down, the gauges show the nitrogen pre-charge level, making it easy to detect pressure loss or imbalance before it becomes a safety concern. This upgrade enhances system reliability and simplifies maintenance diagnostics.

Quantum’s patented Dynamic Load Control (DLC) system is designed to smooth hydraulic and electrical loads by intelligently distributing power demand between pumps during stabilizer operation. This upgrade reduces horsepower spikes, minimizes strain on the generators and hydraulic components, and enhances overall system efficiency. The result is a quieter, more stable system with improved reliability and reduced wear on key equipment, especially under variable roll conditions.
