VULKAN Couplings at MARINTEC 2013

VULKAN Couplings’ focus at the product and service presentation at MARINTEC 2013 in Shanghai shall be on specially integrated drive solutions for suction dredgers and offshore ships.

The couplings manufacturer, which has its head office in Herne, Germany, has been supplying drive components for many years, primarily to the high-growth markets in Brazil and China.

The most recent example of a successful project in Asia was the supply of one of the largest suction dredgers in the world – the Inai Kenanga, which belongs to Inai Kiara SDN BHD, the Malaysian shipping company. VULKAN Couplings has supplied six clutches for the gearboxes of the powerful sand pumps – these clutches are the largest that the company has ever manufactured.

For the two Siemens/Flender 3-gear sand pump gearboxes of GJZ 2250 type, the couplings specialist based in Herne manufactured a total of six MESLU clutches in cooperation with its Chinese subsidiary, WUXI VULKAN; each one of these were of size 540 for shifting to the first gear and there were two smaller MESLU 330 for shifting to the second and third gears.

As a holistic solutions provider for the Inai Kenanga, and apart from the MESLU clutches, VULKAN Couplings is also supplying all highly flexible couplings for both the main as well as the suction pump operation, while RATO S 582Z have been installed for the drive operation; highly flexible RATO R 473Z provide the necessary torsional vibration damping and misaligment compensation in the pump system on the front side.

At this year’s MARINTEC, VULKAN Couplings will be showcasing a MESLU 24 in combination with the highly elastic CRR2320.

For several years there has been an increased commitment on the part of VULKAN towards the segment of the offshore oil and gas industry and this has ensured that the couplings have become particularly well-known in the field of supplying equipment to offshore vessels (FPSO, drilling, semi submersibles, oil-drilling vessels, jack-up rigs and shuttle tankers), and offshore suppliers (such as anchor handling and towing tugs, diving and ROV, oil spill recovery vessels, pipe laying vessels, tug boats and heavy lifting vessels).

VULKAN Couplings will be presenting the entire product portfolio at MARINTEC 2013 for these demanding diesel-electric high-power and high-performance drives: The highly flexible couplings of the RATO series in combination with elastic mounts provide the optimal reduction in vibrations and damping of the propeller excitation.

The company has designed the VULKARDAN G especially for generators and Z-type drives. The coupling can be deployed for both the SAE engine range (size 54-62) and also for the non-SAE engine range (size 84). The torque range of this coupling is 8.0 kNm to 63.00 kNm.

This coupling has been developed for rigidly mounted systems, in which it is possible to dismantle the elastomer without shifting the units connected. As a result of the element design the coupling provides excellent values for power loss in the coupling.

By using a new type of elastomer with proper torsional rigidity CTdyn, the system is also tuned optimally with regard to torsional vibration, so that harmful resonant frequencies are eliminated from the operating speed range and impact on the engine control is prevented.

The experts at WUXI VULKAN shall be welcoming visitors to the MARINTEC in the German pavilion.
