We needed a partner with the experience and in-house expertise to deliver a lightweight, reliable, and environmentally friendly solution, and Wärtsilä Shaft Line Solutions met these requirements.



    Merchant vessels are primarily used for transporting cargo or passengers and range from tankers through containers to bulk carriers. All require robust and reliable equipment capable of withstanding harsh conditions for extended periods of time. With modern operational demands in mind, we deliver hard-wearing, regulatory compliant shaft line solutions designed to meet the demands of our merchant customers.

    Cruise and ferry

    Cruise ships and ferries operate worldwide and make up a large proportion of the tourism industry. Because these passenger vessels spend a considerable time on the water, they require long lasting, robust and regulatory compliant vessel equipment they can rely on. Our shaft line solutions bring maximum operational and environmental efficiency, reliability and high performance so that customers can reduce downtime and focus on the task at hand.

    Cruise ship

    From surveying the seas to safeguarding key trade routes, today’s navies are deployed in operations of varying scope and complexity and require ever more efficient vessels to meet modern military demands. As a leading equipment supplier with manufacturing facilities around the world, we have the means to equip navies with advanced noise reducing, shock resistant, fully integrated solutions capable of performing in the harshest, most demanding environments.

    Offshore and special vessels

    From offshore installation vessels to technically complex research ships and dredgers, we have the skills to overcome a number of marine and offshore market challenges. Years of experience in the marine industry allow Wärtsilä to offer a complete range of propulsion shaft line components designed to operate with minimum disruption and maximum efficiency, even in the harshest of environments.

    Yachts and fishing vessels

    Today, vessel owners and operators are looking for advanced solutions capable of lasting longer, preventing expensive emergency dockings and downtime in harbour, and eliminating leakages and associated costs. At the same time, they need products and spare parts on demand. We deliver both: designing and manufacturing a range of high specification shaft line products in house and offering around-the-clock expert services above and below the water.
