Products include the propulsion condition monitoring service, Wärtsilä 3C

Keeping up with the maintenance schedule of a ship, let alone a fleet of ships, can be a task in itself. Wärtsilä aims to make that process easier with the release of its Propulsion Condition Monitoring Service (PCMS), which is designed to provide customers with real-time data and advanced analytics on the condition of a ship’s propulsion equipment.
Normally, the condition of a vessel is assessed from extensive inspections and functional tests, requiring the operator to station the v ssel at a dry dock for these services, Wärtsilä said. With the PCMS, the operator can apply for thruster condition monitoring, which allows an operator to eliminate the need for visual internal inspections.
This also eliminates the need to enter a dry dock for periodical inspections of the ship’s propulsion equipment, with the necessary paperwork coming from Wärtsilä, the company said. PCMS allows ship operators to prevent damage, lower life-cycle costs and limit their vessel’s environmental impact by keeping the propulsion systems operating at a high efficiency, according to Wärtsilä.
The PCMS measures vibrations, hydraulic pressures, the lubrication oil temperature, oil water saturation and oil contamination, which helps the system monitor gears, bearings, propeller and other propulsion machinery components. It gathers nautical parameters, such as vessel speed, rate of turn and draught, from the vessel’s automation system and all operational parameters from the propulsion control system. It also measures vibrations on the inside of the thrusters using sensors located next to the gears and bearings. The data is processed, stored and sent to Wärtsilä for further analysis.
A PCMS advisory monitor, which acts as the operator interface, is included in the onboard equipment. It is installed on the bridge or in the engine control room, allowing the operator to monitor the operation condition of the vessel’s propulsion machinery. The advisory monitor gathers and provides data from all the PCMS cabinets on the vessel and then transmits it daily to Wärtsilä Propulsion Services for analysis. In the event of irregularities, the system notifies the owner as well as a Wärtsilä propulsion specialist, who is ISO certified in vibration analysis, said the company.
The specialist will write a service recommendation for the irregularity. A ship operator with the PCMS receives a monthly report prepared by propulsion specialists. The report outlines the PCMS’s findings and recommendations from that month, including a list of irregularities that have occurred, the condition of the propulsion equipment and the operational profiles of the equipment and the vessel. The PCMS is available for several propulsion systems and is not restricted to Wärtsilä equipment. Those systems include steerable thrusters, transverse thrusters, controllable pitch propellers, electric pods, water jets and gearboxes, Wärtsilä said.
The standard scope of supply for each unit installed onboard a vessel includes one PCMS cabinet, three to six accelerometers, one inductive proximity sensor, one oil measurement unit, one temperature transmitter, two to four pressure transmitters, a torque management system, an advisory monitor with software, a product guide and an operating manual. Wärtsilä has also launched its communication and control center Wärtsilä 3C which integrates a vessel’s controls and alarms into one interface. It provides route planning, optimal engine configuration and decision support, all designed to reduce fuel consumption and emissions, according to Wärtsilä.
Owners of the Wärtsilä 3C can remotely optimize their assets and achieve real-time fleet management because the system is supported by the company’s global service network. The company’s Land and Sea Academy’s training facilities provide instructions on all the ship’s operating systems through the global network, Wärtsilä said. The communications and control center complies with all major classification societies and notations, and has modularized components and a customized design suitable for all vessel types. Raytheon Anschütz, a provider of advanced maritime navigational systems, supplied the navigation technology used in the Wärtsilä 3C.
