Yara Marine Technologies has signed a contract with Algoma Central Corporation, a Canadian shipping company, to install its FuelOpt propulsion optimisation technology onboard a further eight bulk carriers, following a successful trial onboard the 'Algoma Conveyor' in April 2021.

David Belisle, Vessel Performance Manager, Algoma Central Corporation, said: “At Algoma, we were looking for a solution to improve overall operational efficiency. FuelOpt allows us to maximise the benefits of pitch/rpm regulation possible on our vessels equipped with controllable pitch propellers. Having seen the results achieved in such a short time with the Algoma Conveyor, we have decided to carry our collaboration forward by equipping eight more bulk carriers with the FuelOpt system.”

Belisle acknowledged that this installation offers the additional benefit of allowing Algoma to comply with the IMO’s incoming EEXI framework – a significant concern for many ship operators at this time.

“Our FuelOpt system has had the proven functionality to limit shaft power since 2013 and provides a log of the propulsion data. Therefore, according to our understanding of IMO’s EEXI guidelines, the FuelOpt technology is already meeting ShaPoLi requirements,” said Mikael Laurin, MD Vessel Optimisation, Yara Marine Technologies.

The technology can safely limit shaft power output (ShaPoLi) by allowing ship operators to set an upper limit to shaft power output without any modification to the existing machinery. This allows them to align daily operations with stipulations in the EEXI requirements. The use of ShaPoLi can also be overridden in an emergency, enabling the crew to access to the engine’s full power. Yara Marine is working proactively to obtain class approval as soon as possible.

The FuelOpt system can be installed on newbuildings or retrofitted. It functions regardless of the type of fuel or multiple fuel sources used and is compatible with any type of propeller or engine. As a result, it is forward compatible with upcoming vessel upgrades.

Allowing for direct control of speed, fuel consumption, engine power, or a combination thereof via an intuitive panel on the bridge, the system dynamically controls the vessel propulsion based on the commands set. The system, therefore, adapts propulsive power to changing environmental conditions and erases variations in speed and power, leading to increased efficiency via fuel savings and emissions reduction.

For vessels with a controllable pitch propeller, such as Algoma’s bulk carriers, FuelOpt allows additional efficiency gains through dynamic pitch/rpm optimisation. It regulates propeller pitch and engine rpm separately to operate the engine and propeller at optimal conditions, optimising energy use by achieving the maximum amount of propeller thrust with a minimum amount of power spent.

As proven by the installation onboard the Algoma Conveyor, operating in the Great Lakes – St. Lawrence Seaway, FuelOpt’s use is not restricted to deep-sea operations. This is evident from its use by operators mostly doing shorter line sea voyages such as UECC, Color Line, Bohai Ferry, and Viking Lines.
