    IMCA working on impact of PLCs on SAT diving systems

    Publications // May 20, 2010

    A new generation of diving support vessels (DSVs) is providing challenges for inspectors. The International Marine Contractors Association (IMCA) recognises that certain newbuild DSVs, some of which are on, or shortly due to come onto, the market, have diving systems using programmable logic control (PLC) technology to control applications of their saturation diving systems.
     
    “The introduction of these new control systems could have a significant impact on the application of ‘Diving Equipment Systems Inspection Guidance Note (DESIGN) for Saturation (Bell) Diving Systems’ (IMCA D 024),” explains Jane Bugler, IMCA’s Technical Director.
     
    “We have engaged consultants to help take this issue forward and to help produce IMCA guidance for use by both contractor and client members. This may result in an additional section to IMCA D 024 or the issue of specific guidance for the inspection of such systems.”
     
    In 2009 IMCA issued a warning of its concerns over PLCs in marine operations when publishing a safety flash following a tragic accident suffered by a member company which resulted in four fatalities and four injuries.
     
    A full list of all IMCA documentation and publications is available on their website at www.imca-int.com/documents and is available from IMCA at 52 Grosvenor Gardens, London SW1W 0AR, UK. Tel: +44 (0)20 7824 5520; Fax: +44 (0)20 7824 5521; publications@imca-int.com.
