Tridentis was just awarded a contract through our GSA Professional Engineering Service Contract to provide Marine Engineering Services for the NOAA Ship Thomas Jefferson. The Thomas Jefferson, whose home port is Norfolk, VA is a hydrographic survey vessel that was built by Halter Marine in 1991. This ship is currently a part of a fleet of NOAA survey vessels. The primary mission is to collect and process the data needed to maintain and update nautical charts along the U.S East Coast, Gulf of Mexico, Puerto Rico and the U.S. Virgin Islands.
Our responsibilities include performing the naval architecture and marine engineering services for the design to upgrade the grey water and sewage system to reduce effluent discharge and potable water use. We will provide NOAA with alternatives for upgrading their grey water system by performing numerous feasibility and concept studies. Once an alternative is chosen, our team will prepare a detailed specification and develop design drawings of the new system.read more

We are excited to announce that we will be supporting the United States Coast Guard on the Service Life Extension Program (SLEP) for the USCG Barque Eagle. The Barque Eagle is the tall ship training vessel for the USCG Academy. This vessel was built at the Blohm + Voss Shipyard in Hamburg, Germany in 1936. At the close of WW2 this ship was taken by the U.S. from the Germans as a war reparation. The Eagle’s datasheet can be found here.
Tridentis will be performing naval architecture and marine engineering services to extend the service life of this vessel. This is a multiyear program including a tremendous amount of engineering work. Some of the services we will be providing include:
- Developing an approach to update the anchor windlass with a logistically supportable unit.
- Recapitalizing the entire refrigeration plant with a logistically supportable system. Replacing all of the reefer boxes with a standard Coast Guard configuration.
- Consolidating the compressed air system and redesigning the system to USCG CFR standards for engine starting.
