Container Vessel Sees 30% Diesel Fuel Savings with Nanotech Coatings
Industrial Nanotech, Inc. (Industrial Nanotech) Monday said that their patented Nansulate High Heat temperature control coating (TCC), which has been used in a recent case study to insulate and prevent corrosion on the heavy fuel oil (HFO) system of a 3,725 TEU container ship, has delivered a 30 percent reduction in the amount of diesel fuel required to heat the vessel's HFO system.
"A savings of 30 percent in diesel fuel costs for the HFO systems aboard container ships, cruise ships, and other vessel types and with such a short payback period is significant," said Francesca Crolley, V.P. Business Development for Industrial Nanotech.
"Additionally, that savings doesn't reflect the benefit of reduced replacement and maintenance costs from protecting the HFO system from corrosion."
In addition to reducing diesel fuel use by about 360 liters per 24 hours, the TCC is said to likewise reduce operators' costs, as well as reduce the associated pollution and carbon emissions.
"Besides the positive impact this has on the bottom line of the vessel operators and potential reduced shipping costs, it also means great things for the reduction of carbon emissions and running more sustainable ocean voyages," said Crolley.
"If we use the well-to-wheel fuel emissions factor for diesel oil of 2.9kg CO2/liter, that is a savings each 24 hours of sailing of 1,044 kg of CO2 emissions. For a 21 day voyage, that's a reduction for one vessel of 21,924 kg (24 tonnes) of emissions."
Six Coats of the Nansulate High Heat TCC is reported to have been applied to the vessel's HFO tanks and tubular system for a total cost of $16,100.
Industrial Nanotech says the return on investment for the coating's application was achieved in 95 days of sailing.
In September, Calnetix Technologies, LLC. (Calnetix) announced the release of a white paper on its newly developed "Hydrocurrent" waste heat recovery system that could provide estimated bunker savings of 200 tonnes per year.
