TL;DR: In this paper, the experimental results of towing tank tests in calm water on a single-step hull model are presented, and the same flow conditions are analyzed via Reynolds Averaged Navier-Stokes (RANS) and Large Eddy Simulations (LES), with different moving mesh techniques (overset/chimera and morphing grid), performed at different model speeds.

TL;DR: In this article, the authors proposed a statistical approach based on a multiple linear regression and allowed for both pointwise and interval predictions of the fuel consumption, which can be used to alert management for possible change in ship performance in all those situations where the actual fuel consumption lies outside the prediction interval.

TL;DR: This procedure can be used both to alert technical management of a shipping company for anomalous fuel consumption and to quantify the fuel consumption reduction connected with any specific policy adopted to improve energy efficiency.

TL;DR: A statistical framework and automatic reporting system for fuel consumption monitoring that addresses the MRV requirements needed to comply with the regulations and is shown to be capable of supporting fault detection as well as verifying CO2 savings achieved after energy efficiency initiatives.

TL;DR: In this article, the hydrodynamic forces of single-stepped planing hulls were evaluated by an analytical method and compared against towing tank tests using the 2D + T theory, the pressure distribution over the wedge section entering the water and the normal forces acting on the twoD sections have been computed.
