Demand for advanced propeller retrofits and energy-saving devices (ESDs) has nearly quadrupled since 2020 to enhance energy efficiency to meet tightening emissions regulations.
However, according to a new report from British class society Lloyd’s Register (LR), while high-efficiency propellers can deliver fuel savings of between 3-10%, and popular devices such as rudder bulbs can achieve 3.5% reductions, only 1.74% of the global fleet currently features the rudder bulb, the most popular device, with the report making a strong case for retrofitting, giving clients an idea of payback times for their investments (see below).
The orderbook tells a different story, with 8.42% of vessels on order choosing to install ESDs. The proportion of vessels on the orderbook fitted with a particular device is between two and six times higher than for those vessels already in service.

CMISA posted an articleNEW FUEL-SAVING PROPELLER BOSS CAP see more
EcoNavis Solutions has secured its first commercial contract for the novel Eco Boss Cap, a proprietary energy-saving propeller hub cap introduced to the market last year.
The fuel-saving, emissions-reducing hub will be retrofitted to a general cargo carrier operated by a Thailand-based ship manager. EcoNavis has received two POs from the company, which is evaluating further installations across five more vessels.
Retrofit work to 177m long vessel’s 5m diameter propeller is scheduled for mid-August at an undisclosed Chinese shipyard, close to Shanghai. EcoNavis engineers will supervise the installation and early operation of the device, with sea trials expected shortly after the retrofit.
When commissioned, the installation will mark the first full-scale deployment of the Eco Boss Cap, a conically shaped propeller hub featuring a patented arrangement of internal chambers and holes designed to reduce fuel consumption, emissions, and propeller-induced hub vortex cavitation.
