RTC 10 was originally built at SENESCO in 1999 for service as an acid barge but the owner never took delivery. After several years laid up at SENESCO, Reinauer Transportation decided to convert it for use as an oil barge. The RTC 10 will carry Category D and below cargoes in the Greater Boston area. JMS performed the engineering and plan review to modify the barge for oil service and submit the relevant drawings for USCG approval. The original barge had one cargo tank with two non-tight bulkheads (one longitudinal, one transverse). JMS drafted plans to close the openings and make four cargo tanks. In addition, as-built scantlings were evaluated against ABS Rules. Most structure was adequate; additional vertical stiffeners were required to be added on the centerline longitudinal bulkhead. While SENESCO specified desired equipment, JMS performed a plan review and edited draft drawings for submittal to USCG. Cargo pumps are powered by two hydraulic power units. The electrical system is minimized to strictly navigation lighting powered by a 120 VAC connection to the pushing vessel.
