“…In addition to that, there needs to be continued effort on working with the evaluation tools to allow for many different hullforms to be created and evaluated in a more automated process. An immediate effort is to expand the modeling and simulation environment to include not only ASSET and RSDE but also the Smart Ship System Design (S3D) tool, which has been undergoing extensive development and upgrades to support this type of broad trade space exploration for the latest electric ship technologies [11] [12]. There is also ongoing effort in using templates to aid in design space exploration [10].…”

With the advent of new technologies for electric ships, there is a need for a robust methodology to quantitatively evaluate their impact on the performance of a ship, while accounting for the uncertain nature of their parameters. To that end, this paper gives an overview of the Technology Identification, Evaluation, and Selection, or TIES, methodology as applied a 10kton surface combatant. This case study highlights the ability of TIES to aid in a broad exploration of the design space, by giving designers key tools that allow them to show in a traceable manner the tradeoffs involved in infusing technologies and making other design choices, as well as which designs best meet different sets of Figures of Merit. This ultimately allows decision-makers to determine what technologies or design choices to invest in to yield a ship with the performance parameters that will best serve the needs of its stakeholders.

“…The need for high current density direct current (dc) power cables based on high-temperature superconductors, such as RE-Ba 2 Cu 3 O 7−δ (REBCO) coated conductors, has been growing rapidly in recent years. Several applications that require delivery of 1-10 MW of electric power in confined spaces using dc power cables are naval ships [1,2], electric aircraft [3,4] and potentially within datacenters [5,6]. These applications often require cooling with high-pressure at a current exceeding 4 kA that was cooled with pressurized helium gas and operated at 65 K-70 K [13].…”

High-temperature superconducting (HTS) direct current (dc) power cable systems, capable of delivering power exceeding 10 MW while being cooled with cryogenic helium gas, have been developed for applications on naval electric ships, electric aircraft and in data centers. Current injection from room temperature into the superconducting power cable causes by far the greatest heat load to the cryogenic system. Efficient current leads with integrated helium gas heat exchangers were developed to inject current exceeding 1 kA from room temperature into superconducting Conductor on Round Core (CORC®) power cable, without the need for liquid nitrogen precooling. A 2-meter long, single-pole CORC® power cable system including current leads was cooled using a Stirling cryocooler with closed-loop helium gas circulation system. The turnkey power cable system allowed cool down from room temperature to its operating temperature of 60 – 70 K within 5 hours, after which continuous operation at 1.2 kA was demonstrated. The successful development and demonstration of a CORC® power cable with current leads containing integrated helium gas heat exchangers enables widespread implementation of HTS MW-class, high current density superconducting dc power cables in many applications with constrained space that require a power dense solution.

Modern design processes such as set-based design and TIES (Technology Identification, Evaluation and Selection) depend on the ability to explore a large design space rather than attempting to optimize a single design. In this paper, we investigate methods for expanding the design space that can be explored using the S3D (Smart Ship System Design) software environment. We then detail the most recent advancements in the templating process, with the goal of automated system assembly and evaluation using pre-designed system segments called templates.
