Finnish specialist in azimuth propulsion systems Steerprop has signed a five-year contract with Norway’s Siem Offshore.

Under the contract, Siem will use the Steerprop Care Premium propulsion monitoring system on all three 5,500 dwt Platform Supply Vessels (PSVs). Siem Pride, Siem Symphony, and Siem Thiima. The vessels, equipped with Steerprop propulsion units, operate in Norwegian and Australian waters.

Steerprop Care is designed to improve a vessel’s uptime by continuously monitoring the health of the main propulsion system, revealing any changes in behavior that may indicate upcoming maintenance needs.

“Machine learning guides our predictive maintenance experts to focus on the right metrics at the right time, revealing consequent changes in propulsion system behavior,” says Jarkko Sirrola, PDM Manager at Steerprop. “With this information, our team can work more efficiently and we are able to provide equipment condition information so far in advance that our client can plan for upcoming maintenance as efficiently as possible.”

Sirrola says the new contract with Siem Offshore is an example of the marine industry’s growing interest in streamlining maintenance processes through online monitoring services.

“The new level of predictive maintenance will ultimately lead to improved vessel availability, increased safety and optimized maintenance based on actual propulsion system requirements,” he said. “It also helps to extend overhaul intervals, optimize spare parts consumption and avoid unplanned maintenance.”

“We were interested in Steerprop Care Premium because it offers comfort in using vessels and streamlines the onboard maintenance process,” explains Aaron Barbetti, maritime manager at Siem Offshore in Australia. “The experience so far matches our expectations, and we hope to see long-term dividends with Steerprop.”


The basic version of Steerprop Care is called Standalone and gives the crew on board basic information about the status of the propulsion system. It has been included in every Steeprop propulsion unit delivery since 2019.

The online versions, Steerprop Care Plus and Premium, offer more advanced measurement capabilities, and if there is a development that could cause future disruptions to a vessel, Steerprop’s predictive maintenance team will notify the crew and provide a remote assistance if needed. Steerprop Care Plus and Premium are also available as a retrofit.
