IR-OPTiTRIM - CFD based Trim Optimization tool for Fuel Saving.
IMO 2020 Sulphur cap- Financial Burden
With forthcoming regulation of IMO 2020 Sulphur Cap, Ship owners, Charter parties and operators will be facing steep increase in Capex through Scrubber investments or OPEX through 0.5% sulfur fuels (bunker prices approximately 40% or $200 above the HFO prices). In such situation industry is in need of trustworthy solutions to save on fuel bills. Trim optimization is cheapest measure; which can bring around 5% saving on fuel bills.
IRCLASS developed this simple user-friendly instant tool to calculate fuel saving trim at any speed and draft. It is a standby tool and doesn’t need any integration with other systems.
Uniqueness wrt Market tools – use of CFD
Most of the market-based tools are based on Empirical or Parametric formulas which doesn't give realistic and trust-able results. Parametric formulas don’t consider different motions of ship hull and subsequent resistance values responsible for varying fuel consumption. With advancement of Computational fluid dynamics and Cloud Server technologies, it’s now possible to perform Full scale Computer simulations of ship within lesser time and cheaper rates.
What We need from You?
Voyage data helps to reduce number of simulations as well to decide on various speeds.
Other Applications of this tool
Project under working:
VLCC chosen for case study completes around 6-voyages a year from Gulf to East China.
With optimum trim, vessel showed saving of around 3.27% bunker at 12knots operational speed which amounts to $90,000 a year assuming HSFO at $350/ton. With IMO 2020 complied 0.5% Sulphur fuel, the saving will be more than the above i.e. $1,30,000.
Same way with your ship voyage data and subsequent CFD simulations we can find out possible saving scenarios and optimum trims.
