EcoNavis has introduced a new online savings calculator aimed at helping shipowners and operators estimate the potential fuel savings of installing its Eco Boss Cap technology.
The tool, unveiled by the propulsion technology specialist this week, uses basic vessel data such as ship type, dimensions and power to provide an initial estimate of annual savings across a range of fuel price scenarios. According to the company, the calculator is intended as a first-stage commercial guide before owners commission a more detailed vessel-specific optimisation study.
Its launch comes at a moment when marine fuel economics have shifted sharply. Since the outbreak of the US/Israel-Iran conflict, bunker prices have surged, putting additional pressure on operating costs across the shipping industry. EcoNavis said average bunker prices have risen by more than 150%, while the price of very low sulphur fuel oil in Singapore had climbed 160% by mid-month to around $1,100 per tonne.
That backdrop has made even relatively modest efficiency improvements more valuable. EcoNavis founder and chief executive Dr Batuhan Aktas said shipowners are now confronting a mix of fuel-price volatility and growing regulatory pressure. He noted that when higher bunker prices are combined with carbon costs, small gains in efficiency can quickly translate into meaningful commercial returns.
The Eco Boss Cap is marketed as a lower-cost option compared with many other propeller boss caps currently available. The company says the system can generally be fitted within only a few hours, often during a routine docking, and that typical efficiency gains range between 2% and 4%.
With fuel prices rising so sharply, EcoNavis argues that payback periods for such retrofits are becoming even shorter, strengthening the commercial case for owners to examine efficiency upgrades more closely.
