Nansulate® Heat Shield High Heat Temperature Control Coating (TCC) was applied to the tubular system and tanks of the HFO system for insulation and to prevent corrosion under insulation.
The coating reduced the diesel fuel used to heat the HFO system by 30%, reducing the daily diesel fuel use by 360 liters per 24 hours, which equates to more than 7,500 liters of diesel fuel saved during a typical 21 day round trip Asia/US/Asia journey, equivalent to approximately $3,525 USD or more in cost savings.
The project was undertaken on a 3,725 TEU container vessel. The High Heat insulating and anti-corrosion coating was applied to the HFO tanks and tubular system at a coverage of 6-coats, totaling a 200 micron dry film thickness. The cost of application and materials used to insulate the HFO tanks and tubular systems was $16,100 USD. The return on investment was achieved after 95 days of sailing.
Reduction of Carbon Emissions:
If we use the well-to-wheel emissions factor for diesel oil of 2.9kg CO2/liter, that is a savings each 24 hours of sailing of 1,044kg of CO2 emissions.
For a 21 day voyage, thats a reduction for one vessel of 21,924kg (24 tons) of emissions.
