The Ultimate Project:

THE SHIP Inai Kenanga            

THE SHIPYARD Inai Kiara SDN BHD, Malaysia

THE CHALLENGE One of the largest suction dredgers in the world, Inai Kenanga, is to be launched by Inai Kiara SDN BHD, the Malaysian shipping company. VULKAN Couplings has supplied six MESLU clutches for the shift gearboxes of the powerful sand pumps - these couplings are the largest that the company has ever built.

THE CUSTOMER Centro Experimental Aramar / Iperó, Brazil

THE CHALLENGE The Brazilian government is currently planning the construction of a fleet of six submarines with nuclear propulsion. The planned nuclear submarine however remains the most ambitious projects: with six thousand tons and 96.6 meters in length, the construction will take up to eleven years.

VULKAN Couplings fits the supply ship for the Brazilian offshore industry with composite shafts




In cooperation with local subsidiary VULKAN do Brasil in Itatiba VULKAN Couplings has fitted the drive of the Brazilian offshore supply ship "MARIMAR XIX" of the Brazilian shipyard INACE with composite shafts, highly flexible couplings and elastic mounts.

The powerful drive of the "MARIMAR XIX" is supplied by Sotreq, the biggest Caterpillar dealer in Brazil. The two Caterpillar type C32 Acert engines each have a power of 1450 BHP at 2100 rpm.

THE SHIP Elisabeth Knutsen / Tanker

THE SHIPYARD Remontowa / Danzig

THE CHALLENGE The 265 m long crude oil tanker, with a tonnage of 71,850 GT (dead weight: 124,758 tons), was at the Remontowa shipyard in Danzig for retrofitting, among other things. The four torsionally flexible main drive couplings were replaced thereafter following 100,000 hours of operation.


First DUAL FUEL Electric-driven LNG Carrier
The electric drive with four stroke dual fuel ENGINES

"The dual-fuel-electric machinery concept is far ahead of the competition in terms of evironmental friendliness, reliability, redundancy, maintainability, fuel flexibility, as well as economy and safety," said Mikael Mäkinen, group vice president, Wärtsilä Ship Power. "The recent introduction of heavy fuel oil (HFO) as fuel for the engines´s diesel-mode further enhances fuel flexibility and provides ship operators the highest degree if control over operating costs under fluctuating gas and liquid prices."

THE CHALLENGE The centrepiece of Pavana lll includes sixteen 18-cylinder Wärtsilä V46 engines with a total electrical power of 267.4 MW. The engines have been installed in two separate halls for the sake of safety, but can be monitored from a single control room that is equipped with the latest monitoring equipment and technology provided by Wärtsilä.


VULKAN ESPAÑOLA is supplying highly elastic elastomer couplings for the new oceangoing tugs

THE SHIP Bylgia and Kolga

THE SHIPYARD Astilleros Armón / Pontevedra

THE CHALLENGE For both ocean-going tugs with the hull numbers V-085 and V-086, built at the Spanish shipyard Astilleros Armón for the Heerema shipping company (the Netherlands), VULKAN ESPAÑOLA, a subsidiary of the globally active VULKAN Group, has delivered highly flexible couplings for the main drives, PTO gearboxes and generators. 

Flexible Couplings for floating Disneyland


THE SHIP Disney Dream and Disney Fantasy (Cruise Ships)

THE SHIPYARD Meyer/Papenburg

THE CHALLENGE In August 2009, at the Meyer Werft GmbH shipyard in Papenburg, Germany, the Disney Cruise Line laid down the keel during a festive ceremony. VULKAN Couplings has received the contract to equip the four MAN engines of the cruise ship with RATO S couplings. Another ocean giant, the Disney Fantasy, which has been part of the fleet since 2012, also cruises using the RATO elastomer couplings.
