Digital & Modular Shaft Line Systems

Wärtsilä’s FuTube is a modular shaft line equipment package launched in early 2024, combining stern tubes (EvoTube), bearings (IntelliSafe), seals (Airguard), and monitoring systems to improve reliability, reduce maintenance, and simplify installation.

It is designed to support both newbuild and retrofit projects, though individual module availability depends on Wärtsilä’s specifications, drawings, and class approvals.”
