Systems integration

Wärtsilä SAM Electronics is one of the leading providers of complete electrical and electronic system packages for vessels – we deliver turnkey solutions. The turnkey solutions business unit offers extensive systems integration competence, and acts as an EPC contractor for complete electrical packages – typically in close partnership with the shipyard.

Your benefit is our systems engineering competence, creating smarter solutions with less cost and a shorter installation time. Combining this service with taking overall responsibility for a detailed electrical systems design, our focus is on optimizing the entire onboard system. In this role, we are also responsible for interfacing with all the shipyard’s sub-contractors.


    Design and planning

    The success of a project depends to a large degree on professional project management and monitoring. Therefore, we ensure that the overall project management is assigned to an experienced project manager, supported by a dedicated project team with full responsibility for the successful completion of the contract.

    The design has to comply with all the requirements applicable to the vessel in order to achieve the contracted performance, and to provide the desired functionalities. Therefore, close cooperation with the shipyard and its sub-contractors is essential in creating the optimal design. We have extensive in-house know-how and the experience needed to successfully coordinate and interface all electrical systems and sub-systems to achieve the technical goal.

    Engineering and consulting

    The engineering work requires understanding of the electrical system’s role as part of the vessel’s overall system. Although engineering is normally included in the electrical system design, in special cases engineering can be offered as part of a package or as a stand-alone service. Consulting or assistance in specification preparations is also offered.

    Basic Design

    • Power distribution concept
    • Preliminary short circuit calculation
    • Preliminary load balance
    • Concepts for technical rooms
    • Cable way routing

      Cruise and Ferries

      Passenger vessels range in size from small river ferries to giant cruise ships. The various needs of each ship depend on its type, the ship’s owner and operator, and on the passenger and crew requirements. To provide the appropriate safety, reliability and comfort, the design and development of the exact equipment and systems needed demand specialized capabilities.

      Wärtsilä SAM Electronics serves passenger vessels with a broad scope that covers everything from highly sophisticated and proven system installations, to standardized solutions and individual products for retrofit applications. Our proven expertise is based on intensive involvement in many different projects.


      We have delivered numerous projects requiring customized solutions for smaller sport fishing and sailing yachts, as well as for some of the world´s largest and most complex yachts. We are among the world’s leading suppliers, most notably in the Megayacht segment with vessels of 160 metres or more in length. The unique demands of our projects keep us at the cutting edge of yacht systems technology.

      Our delivery scope includes diesel-electric propulsion, power supply, automation, navigation and dynamic positioning, communication, entertainment, special light and sound outfits, as well as safety and security systems, cable networks and complete installations. Our worldwide network of subsidiaries and partners enables us to provide an efficient, fast, and reliable service to our customers.


      Shipping is already a relatively eco-friendly means of transport. However, further environmental protection measures are necessary and under the motto “Green Shipping”, the maritime industry is taking positive steps towards reducing CO2 emissions and pollution from ships. Nevertheless, new regulations and rising fuel costs are putting pressure on shipping companies.

      We develop innovative state-of-the-art technologies aimed at reducing emissions and operating costs. Our Wärtsilä SAMCon shore connection provides shoreside emissions-free electrical power for vessels while their main and auxiliary engines are disconnected. Our shaft alternators are also becoming more and more popular, since they represent an economic and environmentally-friendly solution for electrical power onboard ships at sea.

      Special Vessels

      Special vessels, such as dredgers, tugboats, pilot boats, rescue boats, cable laying ships, scientific research vessels, survey vessels, icebreakers, and  offshore wind farm installation vessels, are designed primarily to perform specific tasks. They typically have a high demand for onboard technologies, e.g. applications requiring a high power supply, reliable propulsion systems, as well as specific monitoring and control solutions.

      Wärtsilä SAM Electronics provides innovative and custom-made solutions for all types of vessels. We take responsibility for the integration of complete electrical and electronic packages, including turnkey solutions. Achieving customer satisfaction is central to all our work.


      Dredging vessels are designed for excavation activities usually carried out at least partly underwater. They operate in shallow or fresh water areas with the purpose of excavating bottom sediments and disposing of them at a different location, mostly to keep waterways navigable. To perform these tasks, dredgers are equipped with various devices that are specific to dredging operations.

      We provide customized solutions for power generation and distribution, as well as electric drives. The product scope for dredger applications also includes dredger control technology, which permits control of the entire dredging process.


      Wärtsilä SAM Electronics provides navies and shipyards worldwide with turnkey electrical platform solutions, including the following capabilities:

      • Complete project design, development, production and management
      • Power supply, distribution and conversion equipment, as well as switchgear systems and components
      • Special equipment and complete lighting systems
      • Installation work for complex cable systems
      • Degaussing and cathodic corrosion protection systems
      • Navigation systems
      • Integrated logistics support
