Wärtsilä Shaft Line Solutions

Contact: Chris Rowlands

Wärtsilä Shaft Line Solutions specialises in designing, manufacturing and servicing marine shaft line solutions for a wide range of vessels. With a network of professionals, service centres and workshops around the world, we can support ship owners and operators throughout the whole lifespan of a vessel. As an original equipment provider and full system integrator with a team of field service engineers and specialist diving technicians, we can custom engineer shaft line products to specific requirements and service equipment above and below the water. Through our Wärtsilä Shaft Line Repair Services (SLRS), we can provide rapid upgrades and overhauls of marine shaft lines and equipment. Having full control of the product and service process—from design to installation— makes it possible for an entire propulsion system to be fully supported by one supplier. Our expertise extends beyond shaft line products and services to risk management and regulatory environments. We keep up-to-date with the latest legislation to ensure our products comply with global shipping standards, including International Organisation for Standardisation (ISO). We’re equally well-versed in technological trends. Through advanced data analysis; remote guidance, using our Augmented Reality (AR) goggles; and underwater drone technology, we’re harnessing the possibilities of digitalisation and helping to make Wärtsilä’s wider corporate vision for a digitally connected Smart Marine Ecosystem, a reality.
