What Does She Look Like?
Validation of Concept Design
Does the idea make sense?
How does it compare against a diesel-driven vessel?
What does the software do?Accepts input data about a given design, a ferry
route, and a ridership model
Computes Capital Cost Estimate (CapEx) Based on the Ship’s Main Characteristics
Computes Operating Costs Estimate (Opex) Based on the Planned Activities of the Ship
Computes Ticket Price Estimate (Tariff) to Cover Expenses and Meet Client’s Economical Expectations
Why is this useful?
For Design
For Operations
For Procurement
