Wärtsilä Linesafe

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.

Baltic Yachts



    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 are responsible for transporting passengers and make up a large proportion of the tourism industry. Because passenger ships spend a considerable time at sea, they require shaft line equipment they can rely on. Our products bring maximum efficiency, reliability and performance, so that customers can reduce downtime in drydock 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.

    In our position as a leading equipment supplier with manufacturing facilities around the world, we have the means to create fully integrated shaft line solutions for navies. We deliver advanced noise reducing, shock resistant solutions capable of performing in the harshest marine environments and in the most demanding operating conditions.

    Vessel owners and operators are looking for more advanced solutions which can provide value for money by lasting longer, preventing expensive emergency dockings and downtime in harbour, and avoiding leakages and associated costs. At the same time, owners also need fast delivery of seals and bearings products and spare parts. Wärtsilä Shaft Line Solutions' portfolio is designed to improve lifecycle cost management, with a range of custom engineered shaft line products which can provide long service life to owners and operators.
