GyroMetric Proven in Extremes of Maritime use
The marine drive specification of a busy modern harbour tug and a luxury cruise liner could hardly be more different but the commercial consequences of a gearbox failure can be catastrophic in either case. GyroMetric electronic monitoring systems have been proven to provide advanced protection and increased reliability for both situations.
More than 23 ships afloat from tugs to cruise liners are fitted with Gyrometric drive monitoring systems. The monitoring systems are tested to IACS (International Association of Classification Societies) and classified by the American Bureau of Shipping.
Gyrometric marine monitoring systems are sold exclusively via Vulkan www.vulkan.com.
CASE STUDY: Tugs for G&H Towing of Galvaston, USA
The design and build contract for the monitoring system was commissioned by German based marine coupling specialist Vulkan. Measuring 24.4 metres in length, with a breadth of 11.7 metres and a draught of 5.12 metres, the Z-Tech-class tugs are designed primarily for operation in major ports and marine terminals.
During sea trials, the tugs achieved an average speed of 12.3 knots and bollard pulls of 61.1 tonnes. The design of the Z-Tech tug emphasises safe and capable ship-handling operations with large ships, particularly those with extreme flares. The design also offers omni-directional performance capability, with similar ahead and astern speeds and bollard pulls.
For the Gyrometric drive monitoring systems of the Schottel Z drives special programs were written so that torque overloads, such as those caused by propeller obstruction, can be detected and acted upon automatically in less than one tenth of a second.
Gyrometric advanced monitoring systems are also capable of keeping a continuous check of torsional vibrations, which are used to check optimal engine firing and well as the condition of the drive components. The systems may also be used to monitor the centre of rotation of the shafts to high degrees of accuracy, in order to warn of bearing problems and shaft misalignment.
