The high-powered tug Spartan joined the Seabulk fleet, featuring a fully integrated hybrid propulsion plant from Berg Propulsion. The tug is already operational at Port Arthur following delivery by Master Boat Builders, and the Robert Allan-designed RApport 3000 vessel is the first of two 90-ton bollard pull tugs using the Berg package, with the second due in service in Q3 2022.
In addition to Berg MTA 628 azimuthing thrusters, Berg VS3 variable frequency drives with motors, and its own hybrid control system, Berg’s design, supply, and integration includes the switchboard with full power management plus control of the tug’s twin Caterpillar 3512E EPA Tier 4 (2,550 hp) main engines and its gensets - two CAT C18’s and one C7.1.
