sWOIS - Wärtsilä Operator interface system

A smarter way to operate your power plant

The rapid development of computer hardware and operating systems creates obsolescence and availability challenges for power plant operators. In addition, increasing amount of cyber threats is a growing issue. By utilising a virtualised sWOIS built on server hardware and implementing cyber security controls, you can prolong the lifecycle of your HMI systems and mitigate cyber security threats.

Why update your old WOIS/WISE systems?
As power plants age and the control system becomes obsolete, upgrading your control systems to modern modular systems can help improve availability and performance, extend the plant lifecycle and ensure better support. Modern systems improve flexibility by enabling the sharing of process data for remote monitoring and analysis. Up-to-date control systems also help ensure that you can follow grid requirements.
