• VESSEL PERFORMAMCE OF ONE VESSEL IS LOWER THAN THE OTHER IN TERMS OF SLIP, SPEED AND FUEL CONSUMPTION
• PROPELLER BLADES TRIMMED
• RESULT: THE LIGHT RUNNING MARGIN INCREASED AND THE OPTIMUM FUEL CONSUMTPION AND SPEED WAS ACHEIVED

CASE STUDY 3:TRIM & DRAFT OPTIMIZATION
The trim and/or draft of the ship affects the hull resistance and hence the fuel consumption. By actively planning cargo loading and thereby optimizing the trim and draft, one can save fuel and reduce the emissions accordingly.
Trim vs Speed table for a Post Panamax vessel built at Oshima Yard
Red Cells – Indicate Trims which are unfavorable to the vessel’s speed and ME consumption (More than 2.0 % rise in BHP needed for same speed)
Yellow Cells – Indicate Trims with an increase below 2% in Fuel consumption
Green Cells - Indicate trims which are favorable for speed vs ME consumption characteristics
