Advances in High Temperature Superconductors (HTS) are enabling a new class of synchronous rotating machines (Super motors and Super generators) that can generically be categorized as Super machines. Compared to the conventional machines of equivalent rating, these Super machines are less expensive, lighter, more compact and efficient. The field windings are made with HTS conductor material which operates at 35-40 K and can be cooled with inexpensive cryocoolers. These advanced machines are attractive for use and at present they offer significant developments in ship propulsion techniques. In many modern ships, propulsion systems are so large and heavy that they force the rest of the ship to be constructed around them. Large ship propulsion system could be made more compact and lighter by application of High Temperature Superconductor (HTS) technology, thus providing relief from this constraint. HTS machine technology is maturing rapidly and marine ship drive applications are expected to benefit greatly from these advances. This paper discusses the application of HTS machines in ship propulsion. On the basis of experience with recent HTS ship propulsion, it can be concluded that the superconducting rotating machines will deliver superior performance both during steady-state and transient modes of operations. HTS rotating machines will be more compact, lighter, and more efficient than the conventional machines. Naval architects can now begin to translate these propulsion system improvements into increased profitability for ship owners and operators. This progress has been achieved due to the recent progress in key enabling technologies, such as HTS wire and cooling systems. Their small size and weight will translate to lower cost. HTS windings operating at an easily attainable temperature level (~35K), and cooled with low cost and dependable off-the-shelf refrigerators, will result in the fielding of highly reliable superconducting machines. The key technologies essential for the successful development of commercially-viable superconductor machines have been proven and are now sufficiently robust, as well as cost-effective. HTS rotating machines for electrical grid stabilization, industrial and ship applications are just now becoming commercially available and can be expected to become increasingly widespread over the next several years

The advent of high-temperature superconductivity
created the opportunity for quantum leap in the
technology of large electric machines. HTS-based
motors and generators will be smaller, lighter, more
efficient, and less expensive to manufacture,
operate than conventional machines. The potentially
significant cost, size, weight and efficiency benefits of
superconducting machines will change the dynamics of
electrical machinery industry,This unique situation
leads to reduced manufacturing costs.
The initial use for HTS motors will likely in
transportation applications, particularly naval and
commercial ship (marine) electric propulsion, where
critical size and weight savings will provide key
benefit by increasing ship design flexibility. Electric
drive has already penetrated the cruise ship segment of
the market because of its marked advantages over
competing mechanical systems. The increased power
density and operating efficiency as well as other
benefits of HTS based marine propulsion systems will
significantly further expand the attractiveness of
electric propulsion systems, HTS motors are ideal for
use in pumps, fans, compressors, blowers, and belt
drives deployed by utility and industrial customers,
particularly those requiring continuous operation.
These motors will suitable for large process
industries such as steel milling, pulp and paper
processing, mining,chemical, oil and gas refining,
offshore drilling, and other heavy-duty applications.
