This work discusses the implementation of a Unique Ships Grid design that utilizes Energy Storage. This Unique Ships Grid is used to enhance the efficiency of a Construction Single-Hull River Tender previously discussed and assessed by the Army Corps of Engineers and the United States Coast Guard (USCG). This Grid Design is shown to be both in compliance with applicable regulations and reliable due to built-in redundancy. Compliance with regulations and redundancy are both prized by the Maritime Community and the USCG. An applicable Heuristic Design Methodology is provided in conjunction with the Unique Ships Grid. This Design Methodology can be used with a simple load analysis and results in a Load Center breakdown and the sizing of Cables, Generators, Inverter, and required Energy Storage. This design process is shown to provide an inherent margin for growth and safety. This design process is quick and results in values necessary to do a cost analysis, environmental impact survey, and stability analysis (Ship Stability not Electrical Stability). / Master of Science / This work discusses a unique way to power the electric equipment onboard a small ship by using lithium-ion batteries or another safe form of energy storage. The goal of this shipboard power system is to reduce emissions and wear and tear on a small ship. This work demonstrates that the shipboard power system adheres to U.S. Code and is reliable due to inherent redundancy. Reliability and adherence to U.S. Code are necessary for a system to be adopted for maritime applications. The power system is implemented at the level of the controls system and partially relies on conventional methods, such as diesel generators, for powering shipboard electric equipment. This partial reliance on conventional methods for ships power provides for an easy way for industry to transition to more renewable sources of energy. Additionally, this power system is provided with guidance on how to design and customize the system for many applications. The guidance provided on the design methodology is simple, can be easily implemented, and is shown to provide estimates for the power system that provide for reliability and redundancy. The design methodology can be implemented very early in the construction of a ship and provides valuable information needed when building this unique power system.
