USNS Pathfinder
Résumé
USNS Pathfinder (T-AGS 60) is a United States Navy oceanographic survey ship, and the lead vessel of her class. Her mission is to collect acoustical, biological, physical, and geophysical surveys of the world's oceans. This data has many uses, but a primary focus is characterizing the ocean environment in order to improve the U.S. Navy's undersea warfare capabilities.
Halter Marine, Inc. won the contract to build Pathfinder and a second ship of her class in January 1991. The contract price for the two ships was $140 million. Pathfinders keel was laid down on August 18, 1992. The ship was built at Halter Marine's Moss Point, Mississippi shipyard. She was launched on October 7, 1993 and christened by Beverly Nelson, wife of Stewart B. Nelson, the Senior Advisor to the Oceanographer of the Navy.
Her hull is constructed of welded steel plates. She is long, with a beam of , and a draft of . Her full-load displacement is . Her economic cruising speed is , driven by a diesel-electric propulsion system. The system is powered by four diesel generators. These, in turn, drive two General Electric electric motors. Two Wärtsilä LIPS z-drives are driven by the motors, providing both propulsion and steering for the ship. She has a bow thruster to improve maneuverability. The z-drives and bow thruster can be linked in a dynamic positioning system to keep the ship on-station while working. Pathfinder has an unrefueled range of .
The ship has three cranes and five winches to lower and retrieve various instruments. Her instrumentation includes a Kongsburg EM122 multibeam echosounder, and towed sonar arrays. She can also carry a survey launch for work in shallow water.
The ship has a unionized, United States Coast Guard-licensed, civilian crew. Pathfinders research and science missions are conducted by various naval and civilian personnel who change with the ship's changing missions. The ship can accommodate 28 crew and 27 scientists.
The ship is owned by the United States Navy, and managed by the Military Sealift Command, on behalf of the Naval Oceanographic Office.
