Econavis Launches Fuel Savings Calculator

EcoNavis has launched a new online savings calculator to help shipowners and operators make an initial assessment of the fuel-saving potential of an Eco Boss Cap retrofit.

Available on the EcoNavis website (econavis.co.uk), the Eco Boss Cap Savings Estimator allows users to enter basic vessel information – ship type, dimensions, engine power and fuel price – to generate an indicative estimate of annual fuel and cost savings from the novel propeller hub. The tool is intended as a first-stage screening assessment before a full vessel-specific optimization study.

The Eco Boss Cap Savings Estimator draws on indicative modeling across a range of common vessel archetypes, including bulk carriers, tankers and container ships. Across these vessel types, indicative efficiency improvements are in the range of 2.7% to nearly 4%, depending on vessel size, propulsion characteristics and stern configuration.

For example, a 35,000dwt handysize bulk carrier operating a 6000kW main engine for around 250 days per year could reduce annual fuel consumption by about 138t, equivalent to about US$142,968 per year at a VLSFO price of US$1036/mt.

A Panamax bulk carrier could reduce fuel consumption by about 266t per year, equivalent to US$275,576 per year on the same basis. For an 8,000 TEU
