Energy-Efficient Naval Ships of the Future [PDF]

Proceedings OCEANS '83, 1983
The U.S. Navy selected gas turbine propulsion for its most recent classes of cruisers, destroyers, and frigates because of weight, space, and performance advantages, and the ease of automation, of marine gas turbines. These plants, although currently less efficient than diesels and steam plants during certain operating modes, offer the long-range ...

Research on Evaporation Characteristics and Safe Storage Duration of Marine Liquid Hydrogen Storage Tanks Under the Coupling Effect of Heat Leakage and Sloshing

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Liquid hydrogen, a zero‐carbon and high–energy‐density fuel, is a promising option for future oceangoing vessels. During maritime transportation, onboard cryogenic tanks are exposed to ambient heat leakage and ship‐induced roll motion, which can trigger sloshing and fundamentally modify the coupled thermo‐fluid processes governing boil‐off and
