Trinity - Managed Vessels TSV-1 PREVAIL The Navy's first Training Support Vessel: TSV-1 PREVAIL Easily adaptable, the US Government-owned, civilian-crewed TSV-1 PREVAIL is multi-tasked to perform a wide array of military training missions, including OPSEC Monitoring, Threat Simulation, EW Services, MIO Training Support, Cryptologic Training and Mine Laying/Retrieval Operations.  PREVAIL's capacity for simulated warfare training has been continuously enhanced to integrate the latest developments in advancing technology, including improved Threat Simulation capabilities and Multi-drone Launch/Retrieval. TSV-1 PREVAIL is the first of a new designation of "Training Support Vessel" created by the US Navy to coordinate training missions involving carrier battle groups and other fleet-related duties.  TSV-1 PREVAIL replaces the R/V GOSPORT which was retired in 2003 and which had been under contract to Trinity for over 7 years. TSV-1 PREVAIL is 224 feet in length with a beam of 43 feet.  Her documented displacement is 2285 tons.  PREVAIL is an 11 knot, twin screw, diesel-electric vessel with a crew complement of 12 persons and berthing for total of 39 persons. The Dredge Atchafalaya... was the forerunner of a class of small split-hull trailing arm hopper dredges that have proven efficiency in accomplishing various types of dredging projects. Constructed in 1980, the "Chaf" is 197 feet in length and carries a crew of 15 persons.  Atchafalaya is operated by B+B Dredging Company with whom Trinity has successfully contracted for marine personnel management since 1988.  For Deck Officer licensing purposes, Dredge Atchafalaya is USCG-inspected and is rated at less than 1600 gross tons; however employment aboard requires an "Oceans" or "Any Waters" endorsement for licensed personnel.   M/V ATCHAFALAYA Dredge Columbia The Dredge Columbia... originally saw service during WWII as a US Navy LST. Converted to a trailing arm hopper dredge, Columbia has been employed exclusively in the service of the US Corps of Engineers in the waters of the US Gulf, Atlantic Coast and Great Lakes. She is a workhorse and her crew of 16 keeps her digging steadily 24 hrs per day, 7 days per week.  Operated by B+B Dredging Company, the Columbia has carried professional Trinity crew personnel for over 16 years of uninterrupted dredging operations.  Columbia requires licensing for "Unlimited Tonnage" upon "Oceans" or "Any Waters".  Engineering licenses must include endorsement for at least 3000 shaft horsepower.  Propulsion is through a pair of EMD 12 cylinder diesel engines.  The main dredge pump is powered by an EMD 16 cylinder diesel engine.
