Propulsion Dynamics’ new service allows ‘sneak peak’ at vessel’s fuel efficiency

28 Aug 2018

Hull and propeller performance monitoring technology firm Propulsion Dynamics has introduced a new product, Inferred Fuel Performance, which allows a ‘sneak peak’ of a vessel’s expected performance based simply on its type.

Latest reports suggest global shipping fuel costs to rise by $24 billion in 2020 when the new International Maritime Organization (IMO) 0.5% global sulphur cap on fuel takes effect.

The increased cost has resulted in a heightened interest by charterers on the fuel efficiency of their ships, say Propulsion Dynamics.

“Inferred Fuel Performance takes vetting to a new level. It allows the chartering department to have a clear insight of the likely fuel performance of a vessel, based on our database of performance analysis, before chartering-in a vessel,” explains Daniel Kane, Vice President of Propulsion Dynamics’ CASPER® Service.

“Through the ship’s unique IMO number we are able to locate ships of similar dimensions in our CASPER® database, we then take the hydrodynamic correction factors for those ships with similar dimensions and estimate clean ship performance found from trials.

“By considering such factors as the age of the ship, time out of dock, [AIS-based] service patterns and prior hull/propeller treatments – in dock and in water maintenance if available – we are able to assign a likely added resistance to the ship.

“This added resistance factor allows us to create likely fuel performance curves corrected for multiple sea states, draft and speed regimes.”

The process is simplified as there is no sea trial or noon reports required to infer the fuel performance of a vessel.

“Inferred Fuel Performance is part of our commitment to providing not just shipowners and ship managers but charterers too with the tools they need to make big data, analysis-driven decisions based on real-time ship performance information, to further optimize operations and improve energy efficiency,” states Kane.
