“…Due to demanding range requirements, the most commonly studied solutions are hybrid electric marine propulsion systems, which combine mostly diesel internal combustion engines (ICEs) and electric motors (EMs). The integrated electric propulsion concept, consisting of diesel (turbine)-EMs mechanically connected to the propeller shaft with no electric energy storage, has been used in high-level ships since 2004, when the ocean liner RMS Queen Mary 2 was launched [8]- [10]. Conversely, serial hybrid and parallel hybrid propulsion systems are provided with electric energy-storage capabilities [11]- [14].…”

“…Liquid cooling techniques have been extensively applied in the construction of central station utility generators, and could be incorporated into electric propulsion machines. [ 5 ] Potential power-dense electrical machines combine with arrangement flexibility and acoustic benefits to promote electric drive. The following is an evaluation of the effect of incorporating contrarotation into an electric drive submarine.…”

This paper addresses certain issues relating to the viability of contrarotating (CR) electric drive for attack submarines. Topics include CR propulsion's potential benefits, electric drive advantages, and combining contrarotation with electric drive engine room concepts. CR propellers provide propulsive coefficient (PC) increases compared to open-type and performanceenhanced single p r e pellers. The maximum submarine propulsion plant power capacity could therefore be reduced with this PC increase, potentially resulting in a smaller, lighter propulsion plant. This paper concludes, however, that contrarotation shows no propulsion plant weight savings against electric drive attack submarines with performance enhanced single propeller designs. Weight improvements in the power generation plant and certain steam plant and electric plant systems are offset by weight increases from the additional shafting and bearing requirements for the CR shaft. Contrarotation is currently more advantageous for nonnuclear ships, where significant fuel savings are achievable with its higher PC.

During the last five years the Naval Sea Systems Command (NAVSEA) has been studying, developing and revising design alternatives for a major class of mid‐mix surface combatants that will be operating in the surface fleet well into the 21st century. Early tasking directed that design alternatives be investigated to consider innovations, technology developments and cost reduction items while still basing the design on low risk technology. In order to fulfill these directives, comprehensive hull mechanical and electrical (HM & E) technology surveys were conducted. The purpose of these surveys was to identify and assess potential technology developments that could yield acquisition or operational cost reductions or provide significant performance improvements. R & D programs as well as developing technologies in the private sector were reviewed. Numerous trade‐off and design studies were conducted to evaluate concepts. Several of the concepts and developmental systems were incorporated into two different concept design baseline alternatives and presented to higher authority. After initial acceptance of one of the concept design alternatives the subsequent design evolved away from the more innovative concepts to a more conservative design. Many of the concepts initially incorporated into the concept design alternatives are reviewed. However, questions arise such as what risk (if any) is acceptable in the HM & E area for a new major class of ships? What can the designer do to ensure that technological developments affecting HM & E subsystems are exploited to the fullest, yet still minimize risk in the design? An attempt is made to address these questions through the design example presented.
