Tianjin Waterway Bureau (TWB), a unit of China Harbours Engineering Corp. (CHEC), has taken delivery of two new Ellicott® Series 6870 "Super-Dragon®" dredges. The dredges, named "JIN HANG JUN 221" & "JIN HANG JUN 222", are 28" (711 mm) dredges with a combined total installed HP of 13,744 (10,248 KW). Their initial application is maintenance dredging in Tianjin Port.
TWB bought the dredges from Weeks Marine of the USA, who is using a third Ellicott® Series 6870 "Super-Dragon®" for its own fleet. In its initial project, a clean-up job for the U.S. Army Corps of Engineers on the Delaware River, the dredge, the "Weeks #312", produced 1500 yd3/hr on 15,000 ft (4572 m) of pipe. Weeks says that in ideal conditions they expect the dredge to produce 2200 yd3/hr.
