Interschalt Maritime Systems has unveiled its new TROP trim optimisation software to reduce ship fuel consumption.
Since the 1990s, German shipowners have used models in towing tests to determine the trim that produced the lowest resistance as a ship moved through water.
Trim optimisation has been used for testing vessels’ fuel consumption, which showed a slightly lower forward draft yielded the ideal trim.
Based on these tests, the company has included the new TROP trim optimisation module into its MACS3 loading computer system, which helps in filling the tanks to achieve the ideal trim and measuring stability and strength.
Interschalt software developer Bernhard Finke said that currently towing tests can be realistically and economically simulated with the software.
"The user can now even automatically determine the best ballast distribution necessary to save the greatest amount of fuel."
The TROP system can also take into account safety regulations regarding stability and strength while making its calculations.
The new software helps in achieving fuel savings of 2%-3% on ships of 7,500teu capacity operating at a speed of 20 knots, according to Interschalt.
Interschalt claims that if bunker fuel price is around $600 per tonne, a vessel can save around $1,500 to $2,200 per day.
