Q and A Amendment No.3 RFP 693JF726R000016-URN Vessel Design Challenge.pdf

This document is Amendment No. 3 to a federal solicitation addressing clarifying questions regarding the URN-Vessel Design Challenge (Solicitation No. 693JF726R000016).

The amendment responds to two questions regarding the scope and methodology of the challenge. MARAD confirms that the challenge is primarily focused on design-stage studies in which fuel efficiency and Underway Replenishment (URN) benefits are predicted through fluid dynamic modeling. The agency emphasizes that the goal is to demonstrate, through modeling approaches, the benefits achievable through systematic design integration of technologies with input from naval architects, shipyards, and technology suppliers, with no limitation on the type of modeling techniques employed. Additionally, MARAD clarifies that this is a design-stage challenge that does not include an expectation of direct measurement, meaning submissions should rely on analytical and computational methods rather than physical testing or measurements.
