A second series of cavitation tests have confirmed EcoMarine Innovations’ Holy Boss Cap(HBC) propeller hub improves fuel efficiency by up to 5% at full scale, as shipowners and propeller manufacturers vie for licensing agreements.
Full scale CFD simulation of a ship operating at a design speed of 16.46 knots and turning a controllable pitch propeller with four different boss-cap models, found the Holy Boss Cap the more efficient solution, outperforming existing hubs by a factor of 2.5 or more.
Test results mean that the simple-to-manufacture and install propeller hub can be retrofitted to large ocean-going ships as a way of contributing to shipowner ESG goals to reduce carbon emissions.
According to Dr. Aktas, EcoMarine Innovations is currently in negotiations with several propeller manufacturers for licensing opportunities and has also held meetings with a Turkish ship operator. A pilot installation on a Kamsarmax vessel is planned in the second half of 2024.
A key differentiating aspect of the Holy Boss Cap is the emphasis on cost-effectiveness and ease of manufacturing. Unlike conventional propeller boss cap fins(PBCF) which are complex and expensive to produce, the Holy Boss Cap offers a simpler and more economical solution without compromising on efficiency or performance. Its design allows for significant reductions in fuel consumption and emissions, addressing urgent needs within the maritime industry for sustainability and compliance with international environmental regulations.
Ship maintenance costs can also be reduced as propeller hub vortex cavitation is the primary source of rudder cavitation and damage.
In addition to the reduced fuel consumption and carbon emissions, another positive environmental benefit of the HBC is that it reduces underwater radiated noise and vibration levels, which impacts the migratory, mating and feeding habits of marine mammals.
