History

SS Petersburg was part of the Ready Reserve Force. She was scrapped in June 2022. Previously, she was berthed in the Suisun Bay Reserve fleet, Benicia, California; prior to that she had served ten years at the island of Guam. In June 2006, the ship participated in exercise Valiant Shield. The ship occasionally left berth in the ready reserve fleet to participate in active and operational training and exercises.

Originally built in 1963, the Petersburg was one in a fleet of five tankers fitted with an offshore petroleum discharge system. She could carry up to 225,000 barrels of JP8 fuel.

Offshore Petroleum Distribution System (OPDS) provides a semipermanent, all-weather facility for bulk transfer of refined bulk petroleum (e.g., JP5 and JP8) directly from an offshore tanker to a beach termination unit (BTU) located immediately inland from the high-water mark. POL then is either transported inland or stored in the beach support area. Major OPDS components are: the OPDS tanker with booster pumps and spread mooring winches, a recoverable single-anchor leg mooring (SALM) to accommodate four tankers up to 70,000 DWT, ship to SALM hose lines, up to four miles of six-inch (internal diameter) conduit for pumping to the beach, and two BTUs to interface with the shoreside systems.

Three of the tankers (SS Petersburg, SS Chesapeake, and SS Mount Washington) contained a crane and stowage cradles for five OPDS utility boats (OUBs) (modified LCM-6s). OUB-equipped tankers carried adequate SLWT outfitting to equip one SLWT as a towtug and one SLWT as a lay repair boat carry one complete tanker terminal, and were equipped with five OUBs to deploy it. These tankers also had a maximum 59 LT capacity crane to load/offload the five OUBs carried on board.
