Pier 91 Cruise Ship Terminal Study: Ships moored at Pier 91 experienced problems connecting to shore power and had to remain on ship power while in port, which is in violation of several local ordinances for clean air. Our assessments determined that an issue with the voltage regulation at the transformers leading to the ships was causing the problem. We worked with the cruise lines at the terminal to identify the need for a new transformer that could provide the required voltage regulation to serve the cruise ships. This project was part of six-year on-call contract for the Utility.
