IHC Systems aims to help contractors stay ahead of the curve by retrofitting and renovating control and automation systems aboard dredgers We've seen a steady evolution since the 1960s - and it's not ended yet - from those simple beginnings when the dredge pump's vacuum was the sum of 'instrumentation and automation', an IHC spokesman told DPC."Things stepped up with the introduction of velocity, density and other instrumentation, as well as the wholesale application of electromagnetic control of hydraulic installations. It then moved on in the 1970s with the emergence of on board mainframe and microcomputers, through the robust and reliable freely programmable logic controller (PLC) of the mid-1980s, into the full communicating PLC/SCADA/ touchscreen combination that is the current hardware standard."
