WITH MANY SUPERYACHT NEW BUILDS EXCEEDING 80M IN LENGTH STABILISATION CONTROL IS EVEN MORE CRITICAL. GYROMARINE LOOKS AT LARGE CAPACITY CONTROLLER MOMENT GYROSCOPES

GyroMarine designs and produces gyroscopic stabilisers made for the marine industry, specialising in the megayachting, military and offshore sectors for vessels with a length exceeding 50 meters. Headquartered in Tuscany, Rosignano (Livorno), the company is part of an industrial group with decades of experience in mechanical design, engineering and production.

A passion for research and innovation drives the multi-disciplinary, international GyroMarine team, overseeing every production phase in-house, from design to final testing and installation. All activities are conducted with the support of the company’s global industrial subsidiaries.

The organisation benefits from a vast pool of expertise and experience, from marine product design to production and support activities for large offshore engineering and undersea projects, and from the chemical industry to the commercial aerospace and energy sectors.

The multi disciplinary approach and capability is reflected in every activity, from design to production up to and including after-installation support services. The company’s solid financial stability ensures the implementation and support of ongoing projects through to completion and installation.

Experience has shown that active drive is essential to effectively meet the stabilisation demands of large vessels. The solution is the innovative Active Drive new technology developed by GyroMarine. This ensures a level of comfort and safety unequalled by other available technologies.

A gyroscope, which is subjected to roll motion, will develop a natural precession torque that will tend to naturally drive the gyroscope to move in its gimbals. Movement of the gyroscope rotor assembly within its frame is referred to as Precession. The natural driving torque depends on the gyroscope’s angular momentum (how big and fast the rotor is spinning), the ship’s roll rate and the instantaneous orientation of the rotor assembly.

The natural precession driving torque is immediate; but it must overcome the friction and inertia of the rotor assembly; inclusive of its drive and brake mechanism, before movement will commence.

GyroMarine gyroscopes can be located anywhere on the ship with equal effect. This includes offset from centreline or offset about centre of gravity; vertically or longitudinally. GyroMarine manufactures a range of gyroscopes with stabilising capacities from 150,000 Nms to 1,500,000 Nms of angular momentum.

The GyroMarine Active Drive Gyroscope is designed and installed to guarantee optimal usability. The operator interface is intuitive and allows direct, continuous monitoring of all the variables of interest (energy consumed, temperature, roll and pitch). It’s simplicity is also reflected in the sophisticated, minimalist elegance of the device itself, that can be integrated seamlessly into the most prestigious of naval architecture design projects.

All these features make GyroMarine’s Active Drive Gyroscope the effective solution to the stabilisation demands of large vessels available in the marketplace.
