VULKAN composite shafts consist of wound carbon fibre or glass fibre composite materials and are much lighter than comparable steel shafts. The "MARIMAR XIX" supply ship benefits enormously from the use of VULKAN composite shafts: Thanks to the reduction in weight achieved with them, the authorised speed of the ship can be guaranteed. VULKAN composite shafts have a high critical bending speed, which means that intermediate bearings are usually not necessary, even for long shafts. METAFLEX couplings with composite intermediate shafts are largely homokinetic and thus free of the usual second order reaction forces of a cardan shaft, they are free of play, independent of rotation direction and simple to install.
Further Benefit: The complete solution provider VULKAN not only worked to adapt the drive optimally to torsional vibration conditions in the "MARIMAR XIX", but also to protect people and equipment from disruptive engine vibrations. As well as noise for crew and passengers, which can be damaging to health in the long term, these vibrations can also cause serious damage to the drive system. Elastic mounts by VULKAN insulate structure-borne noise in a highly efficient manner and thus prevent both damaging vibrations and unnecessary noise.
