IMCA Advisory on Use of Equipment Controlled by PLC's
The International Marine Contractors Association (IMCA) advises on safe use of Programmable Logic Controllers (PLC's). Programmable Logic Controllers (PLCs) are widely used in a variety of small and large pieces of equipment on marine construction vessels, for example, cranes, winches, handling systems, dive systems and power management systems. The International Marine Contractors Association (IMCA) has issued a PLC information note to help ensure that operation and failure modes are understood, and highlighting the importance of carrying out an FMEA (failure modes and effects analysis) and testing the components and complete systems.
