Wärtsilä Power Management System

Wärtsilä PMS “When blackout is not an option”

The Power Management System controls power generation and power distribution onboard the ship, to secure enough available power for propulsion and manoeuvring.  A complete Wärtsilä solution, including PMS, ensures an optimal tuned system that will reduce the risk of bad performance and blackouts.

PMS from Wärtsilä contains all standard functions like load dependant start/stop, load sharing, synchronising, load shedding etc. The system has several advanced options that will reduce distribution losses, increase the energy availability and save space and installation costs. For use in the offshore market, Wärtsilä PMS has passed stringent tests like Hardware-in-loop (HIL) tests from third party verification companies.

Wärtsilä PMS is fully integrated in WIAS.

    Design Criteria

    Wärtsilä automation systems are designed to provide a high level of safety, economy, reliability and availability through the whole life-cycle of a vessel.

    The design is based on use of Commercial off-the-shelf (COTS) components and a high level of standardization. This reduces building costs, secures high availability of spare parts and keeps maintenance costs down. As process stations, Programmable Logic Controllers (PLCs) are used, while Personal Computers (PCs) contain the graphical user interface and storage of historical alarm and trend data.

    The number of, and configuration/topology of the automation system varies from delivery to delivery, and depends on ship type and size, as well as customer requirements.

    Reduce lifecycle costs

    Wärtsilä automation products enable our customers to operate their vessels more efficient and safe. The operator stations are designed for optimal, user-friendly operation and functionality. The system is integrated with Wärtsilä engines and propulsion products, to achieve the best lifetime efficiency and reliability in the market.


    •         Reduced interfaces (Wärtsilä products have standard interfaces)
    •         Save cabling (due to plugged interfaces on communication)
    •         Easy cable termination (due to spring terminations)
    •         Wärtsilä is the single point of contact

    Operation & Maintenance

    •         Reduced lifecycle cost (due to optimum monitoring and alarm handling of Wärtsilä products)
    •         Reliability - redundant system
    •         Spare Parts available world-wide
    •         Performance monitoring
    •         User-friendly operation
    •         Interface available to Condition Based Maintenance System
    •         24/7 Global Services

    Wärtsilä Ecometer – When fuel waste is not an option

    The Ecometer function in WIAS estimates fuel consumption and assist the operator on how to operate the vessel the optimal way, to save fuel. The Ecometer is developed for Diesel Electric propulsion, and based on Wärtsiläs expert knowledge on diesel electric propulsion systems, and propeller and hull design. Using information from PMS, propeller curves and hull design as well as data from ECDIS it is possible to plan the route based on upon minimum fuel consumption.

    Fuel consumption reports can be generated for the different operating profiles (like steaming, DP and harbor). Saving fuel reduces operating costs and saves the environment.

    • WSD 1000
      “We wanted to ‘Asianise’ the design to make it more suitable for Asia Pacific. Through consultation with our customer Bumi Armada, which has extensive experience in the Asian trade, and Wärtsilä, whom we have been working closely with for over a decade, we decided on the WSD 1000.”
      Leong Seng Keat, CEO, Nam Cheong Holdings
