Description of the data
datacite.resourceType

Data is provided in 6 files, named parametric_analysis_1 to parametric_analysis_6. Assumptions: Only metallic cylindrical tanks are considered No fuel consumption is taken into account. Convective heat transfer coefficient between the vapor ammonia and the tank wall is taken equal to 800 Wm-2K-1 Convective heat transfer coefficient between the liquid ammonia and the tank wall is taken equal to 1500 Wm-2K-1 Thermal conductivity of PU is taken equal to 0.024Wm-1K-1 Thermal conductivity of stone wool is taken equal to 0.004Wm-1K-1 Thermal conductivity of tank wall is taken equal to 52Wm-1K-1

Abstract of the dataset
dc.description.abstract

This dataset was generated using a Simulink model developed as part of a digital platform to support the conceptual design of ships utilizing ammonia. The model simulates a metallic tank filled with ammonia under an initial predefined pressure and liquid volume fraction, analyzing its boil-off rate and holding time.

Project abstract
opara.project.description

Waterborne transport currently accounts for a quarter of the European Union’s (EU) greenhouse gas (GHG) emissions and this figure continues to rise as demand grows. European Green Deal Strategy seeks for a 90% reduction in emissions by 2050 through the introduction of more sustainable, affordable, accessible, healthier and cleaner alternatives. Analyzing the air emissions caused at a mode level, waterborne transport occupies by far the largest part of cargo transport, and accounts for 13% of GHG emissions in the EU. A drastic course of action will need to be deployed so as emissions from waterborne transport start to decline. The NH3CRAFT project develops a next generation sustainable, commercially attractive and safe technology for high-volume storage and transportation of ammonia as fuel on-board ships. The process will be realized by developing new design methodology that will offer the feasibility of 1,000 cubic meter storage of ammonia (NH3) in liquid form at a pressure of 10 bar and demonstrating it on a 31,000 deadweight ton multi-purpose vessel. In addition, for ensuring the wider applicability and refinement of the developed methodology, five (5) different type of vessels and corresponding fuel-storage tanks concepts will be studied and documented.
