Ship Design and Economics – Solar v/s Diesel
A tool to design the vessel from hull form/offsets as starting to check stability, resistance estimation, propeller design. Once we have powering we can size the system and work out the economics comparing a solar electric with diesel.
Barge Economics
The NW-5 Inland Barge Economic Calculator models a 2000-tonne cargo barge on the 320 km Talcher–Paradip/Dhamra route over 28 years. It compares diesel vs battery-swap electric propulsion across TCO, NPV, payback, sensitivity, and emissions — with every assumption visible and key inputs adjustable.
Solar + Grid CO2 Electrification
Does electrifying a ferry actually cut emissions? It depends on what charges the battery. This calculator takes your grid’s carbon intensity and solar share, then shows the resulting CO₂ reduction ratio — and the break-even point where electrification truly starts paying off.
