Eight Cat marine engines re-power US Army dredge

摘要

The US Army Corps of Engineers operates two hopper dredges on the west coast of the USA to keep shipping channels open. The largest and most modern of these is the Essayons, built by Bath Iron Works in Bath, Maine, in 1982. Its aging power plant has recently been replaced by eight Cat marine engines totalling more than 15 000kW.rnThe 106.7M long Essayons is based in Portland, Oregon. Its annual schedule includes work in harbours between Alaska and California, as well as Hawaii.
