Abstract :
Dry-type transformers are typically selected for steel vessels but are now virtually required for mobile vessels and platforms seeking ABS classification. A recent ruling by the ABS and renewed enforcement will require the use of dry-type transformers in areas not exposed to the marine environment. The pertinent publications and rulings will be reviewed as well as standards. This change will affect studies and specification for all future projects seeking ABS classification. Dry-type transformers are almost always required for installation, operations, and maintenance in marine applications. Higher quality dry-type transformers are available which can withstand severe testing and operational environments. Improved characteristics such as self-extinguishing and complete elimination of liquids necessitate a review of IEEE maintenance requirements. Regulatory requirements, reduced fluid handling, and simplicity of operations make dry-type transformers the typical choice for floating hull applications.
