Inland, river barges are often of relatively low draught and narrow to facilitate movement through confined waterways. Barges may transported individually or strapped together in groups depending upon the power of the vessels and sea or waterway conditions such as width and depth of the waterway. For these barges, tugboats, towboats or tenders are used to tow or push the transport barges to and from the dredging and disposal sites. Some barges may be self-propelled, but in many cases they are not. Sometimes the barges are unloaded using hydraulic pumps or mechanical equipment. The barges then transport the material to a designated area, where material is unloaded from the barges by being released through the bottom either through cable or hydraulically operated doors, or in the case of split-hulled barges by splitting the barge longitudinally. Dredged material is loaded onto barges moored close to the dredger. Our next-level cyber security services leverage decades of expertise across the maritime industry, including smart ships, networks, telecommunications, ship design, and safety and security of ship operations. As a result, ship owners and managers must understand that cyber security is integral to safety management in shipping and offshore operations.īureau Veritas takes cyber security seriously, identifying it as a key challenge for shipping. Sophisticated-and often successful-cyber-attacks are a reality worldwide. At the same time, digitalization also poses new problems for the shipping industry. Intelligent data and r eal-time, connected equipmen t have made a world of difference for dredger operations.
