Marine History

The history of Tony Demaria Electric goes back to when Anthony Demaria, Sr. was in the Navy during World War II. One of Anthony Sr.’s jobs during the war was to maintain electric generators along the coast of Florida to provide power to radar installations.
This knowledge assisted Anthony Sr. as he went to sea after the war, attaining his Chief Engineer’s License. After 10 years of working aboard various sea-going crafts, he went to work for Seaboard Electric performing shipboard electrical work. In 1977, he started his own electrical business, catering entirely to the Marine Industry.

Anthony Sr.’s four (4) sons and two (2) son-in-laws joined the business over the years, and it was expanded to work at sea terminals and heavy industrial facilities. At 88 years of age, Anthony Sr. still comes to work. Anthony Jr. operates Tony Demaria Electric (TDE). The other brothers operate Demaria Motor Services, a large motor rewind, repair and machine shop, and DCI which performs testing and construction. All the family works together with their different electrical businesses and have substantial involvement in the marine industry.

Today’s ships have large complex electrical systems that must be very reliable for operations, safety and environmental concerns. Refrigerated containers on freighters, bow thrusters and electrical propulsion have resulted in requiring medium voltage generating capacity of 50 Megawatts and beyond.

Some interesting recent projects by TDE are:

  1. A large tanker had saltwater intrusion and flooded one of their main medium-voltage generators. TDE was brought in to assess the damage and determine what could be done to get them back on line quickly. We steam cleaned the generator and then built a temporary insulated house around the generator to bake out the moisture. After drying and testing the windings, the generator was put back in service. The customer was very pleased that this could be done at such a short time with minimum expense.
  2. A tug boat had some battery cells burst, causing an extensive electrical fire. TDE worked 7 days a week, 12 hours a day. All damaged wires were replaced. The generators and electric propulsion motors were cleaned and tested, and the system was put back on line.
  3. A foreign freighter had a diesel fuel line burst, causing an extensive fire that burnt a majority of the wiring in the engine room and destroyed all electrical drawings. TDE successfully re-wired the engine room, cleaned and tested the generators, and put everything back into service. This took several months, and the customer was pleased that the task was performed along side of the dock without having to go into a shipyard.
