Wärtsilä unveils shaft monitoring system

Wärtsilä has introduced its new Sea-Master system, used to monitor the condition of tail shaft equipment by employing digital technology to monitor shaft bearings and seals.

{mprestriction ids="1,2"}The system collects real-time data from the tail shaft of the vessel, providing information about the operational health of the tail shaft equipment. The new system can be applied to open and closed loop water-lubricated stern tubes as well as closed loop oil-lubricated stern tubes, using digital technology coupled with composite components and existing seals.

Wärtsilä Sea-Master also provides early warning for the detection of rising failure issues with system alarms for critical path components, including bearing temperatures and lubrication rates. The company says that the system is approved by relevant classification societies and is available for all vessel segments and ship types as well as for new build and retrofit applications.

“We used our existing condition monitoring technology to develop this new system and service, which applies proven data analysis methodology to deliver not only information but careful expert analysis and performance-enhancing recommendations as well,” said Matthew Bignell, sales development manager, Wärtsilä Seals & Bearings.

“Our customers get a window into the operational health of their tail shaft and gain knowledge about, for instance, the wear rates of the equipment. This allows for more accurate maintenance planning and reduces unforeseen risks.”

"Our goal is to help our customers optimise their operations by providing safe, reliable and environmentally sound solutions that ensure the health of their equipment. This goal also steers our product development and digital initiatives. Wärtsilä Sea-Master is a good example of the advances offered by digitalisation to the maintenance of propulsion technology.”

Pilot vessels with the Sea-Master system are already in operation, and a number of retrofit programmes are planned starting from September 2016.{/mprestriction}
