Port Call & Route Logistics Assessment

Vizhinjam Advantage: Natural 20m depth eliminates lightering requirements for 15.2m deep-draft megamax vessels, saving ~2.4 days port turnaround.

Stability & Ballast Protocol: 36,960 MT sea water intake necessary to compensate for 92,400 MT container discharge and maintain metacentric height (GM).

Hydrodynamic Fuel Efficiency: Draft reduction from 15.2m to 9.6m reduces wetted surface area, cutting corridor drag power demand by ~21.4%.
