Superior performance, High-speed engine compatible & Environmental performance

Tugs & pushboats

The marine industry is increasingly turning to more advanced solutions as the cost of available technology decreases, and its reliability is substantiated. The environmental and economic viability of these complex solutions typically results from an integrated approach, encompassing vessel design, equipment selection, and on-site support for the shipyard and owner.

No other company in the world can match Wärtsilä’s extensive portfolio of products, systems and solutions for tugs from 700kw to the largest in the market. We serve Conventional, LNG and Hybrid tug vessels with complete power and propulsion systems, electrical and automation technology, a range of environmental solutions and much more, all of which are tailored to suit your operational needs. We are also able to provide a range of environmental ship designs where we are able to fully integrate these products and systems to ensure greater efficiency and lower operating costs. Furthermore, our Smart Vessel Technology provides cutting edge solutions for our customers needs. 


Tugs 207th birthday! While Wärtsilä was established in 1834 the first tug was invented in 1810 making tugs over 207 years old”


    The bollard pull is the leading requirement for tugs, and Wartsila's WST Thrusters will give you the edge.

    There are two main tug types: those with their propulsion aft and towing point near amidships, i.e. conventional ones, or those with their towing point aft and propulsion forward of amidships, i.e. tractor tugs. Tugs with azimuthing propulsion, either Z-drive or cycloidal, have effectively displaced single or twin screw tugs.


    Wärtsilä has an important role in meeting the world’s increased demand for energy in a sustainable way. This is the cornerstone of our commitment to sustainability. Climate change and scarcity of natural resources call for innovative and creative solutions.

    Emission Reduction

    The Wärtsilä LNG & hybrid systems are designed and integrated to optimise the overall operation of the vessel. The system ensures fuel savings and reduced maintenance costs, in addition to substantial reductions in emissions. By increasing the power redundancy, the system allows the engine to operate closer to its optimum design point where it has highest efficiency and least emissions. This will result in reduced maintenance need and increased system performance. Rapid response from the battery system are also among the benefits offered.


    LNG fuelled tug

    Wärtsilä dual-fuel (DF) engines provide the flexibility to select the most suitable fuel according to availability, price and local environmental restrictions. The flexibility of the dual-fuel engine technology also ensures a high level of operational security since the switch from gas to diesel can be made at any time without loss of speed or power.

    The Wärtsilä LNGPac is a complete fuel gas handling system for LNG fuelled ships. It includes the bunkering station, the LNG tank and related process equipment, as well as the control and monitoring system.  Since they typically operate in or close to harbours, tugs are particularly affected by environmental regulations, and the need for compliance is an increasing concern for tug owners and operators. As a technological enabler our responsibility is to develop such products and solutions that allow our customers to develop their own business in a sustainable way.

    Business White Paper: Wärtsilä HY TUG propulsion system

    With regulatory compliance becoming more and more of a global issue, Wärtsilä is launching new propulsion systems for tugs emphasising environmental sustainability. The systems have been developed utilising the company’s strong competences in hybrid propulsion technology. Since tugs typically operate in or close to harbours, they are particularly affected by environmental considerations, and the need to reduce emissions is an increasing concern for tug owners and operators.

    System integration enables further efficiency improvements, while customers benefit from having proven solutions from a single supplier. With lifecycle support, yards can better optimise their building schedules and owners get proven solutions that are easier to manage. This enables full integration of the overall system for greater efficiency, while also reducing possible scheduling risks for the owner and shipyard. 

    Hybrid Tug

    The variety of missions and skills required to crew a tug mean it is a demanding and critical role in ports and coastal areas across the globe. To meet these demands we know a tug needs to be reliable, efficient and above all safe in every operating profile.
    Our systems and solutions fit tugs from 700kw to the largest in the market. With the need to have flexibility and sustainable solutions we are able to deliver highly efficient conventional or LNG and hybrid tug vessels with complete power and propulsion systems, electrical and automation technology, a range of environmental solutions and much more, all of which are tailored to suit your operational needs. Our smart marine solutions are also bringing new technologies to increase efficiency and reduce costs in a safety conscious environment from smart navigation between missions to situational awareness for safety Wärtsilä is the partner you can rely on to pull it's weight.
    Our deep cooperation with Wärtsilä will also ensure additional potential achievements during the vessel’s lifecycle.
