Wartsila, the Finnish engineering group, says it will launch its Sea-Master system to monitor shaft bearings and seals at the SMM trade show in Hamburg 6 to 9 September. The system collects real time data from the tail shaft of the vessel, providing real time information about its operational health. The system can be used in all vessel types and it can be retrofitted in existing vessels as well as used in newbuildings, the company said.
