Dry-Type Transformers: Specification, Installation, and Operational Impacts in a Marine Environment

Dry-type transformers are typically selected for steel vessels but are now virtually required for mobile vessels and platforms looking for American Bureau of Shipping (ABS) classification.

In this article, the pertinent publications and rulings as well as standards will be reviewed. This change will affect studies and specifications for all future projects seeking ABS classification.
