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'', , and ) 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.
