Description

Wärtsilä Shaft Line Solutions brings together several shaft line technologies aimed at improving vessel efficiency, performance and availability.

Products

  • EvoTube®: shaft line technology suitable for both oil- and water-lubricated systems, with a compact, simplified design and low risk profile
  • 10-Years Airguard Seal: stern tube seal based on Wärtsilä Airguard, using a constant flow of compressed air into the void space to prevent oil leaking outboard or seawater entering the stern tube; ten years of operation without replacing seal rings and lifetime cost savings of up to 59% compared with conventional seals
  • IntelliSafe®: self-regulating bearing that is more robust against unfavourable operating conditions and significantly extends bearing life
  • Shaft Line Monitoring Equipment: real-time monitoring of shaft line condition with simultaneous sampling of all input channels, deviation detection and logging for preventive maintenance
