DEME Group Building the World's First LNG-Powered Dredges

摘要

The DEME Group of Belgium has ordered three liquefied natural gas (LNG)-powered trailing suction hopper dredges, to be built by Royal IHC. They will be the first LNG-powered dredges in the world. Dredges running on LNG will produce 25 percent less carbon dioxide emissions than those running on diesel, with practically no sulfur and particle emissions, complying automatically with international emission regulations. The first order, for two dredges, was placed with Royal IHC in April 2015. They are the 10,500 cubic yard (8,000 cubic meter) capacity Scheldt River, an Antigoon class hopper dredge, and the 4,500 cubic yard (3,500 cubic meter) Minerva, a new generation hopper dredge that will replace the Orwell class.
