DNV has announced a ‘new and more user-friendly version’ of its standard for offshore integrated software dependent systems (ISDS) a.k.a. OS-D203. ISDS is an offshore standard (DNV-OS-D203) and guideline document (DNV-RP-D201) for verification and classification of systems using ‘extensive software control.’ The new version updates the original 2009 publication that has been applied by oil companies, equipment suppliers and rig owners. The standard covers system and software quality assurance processes and provides a framework for assessing reliability, availability, maintainability and safety of such systems. The 100 page document contains plethoric definitions of terms, tables and other minutiae such that one wonders what the earlier less ‘user friendly’ version might have been like. According to the standard’s Wikipedia page, the qualification process, which starts at the requirements specification stage of a new project, is performed ‘in collaboration with DNV specialists.’
System integrators and suppliers are evaluated to ensure they have the prerequisites for delivering good quality software. The process is tracked through ‘systematic reviews, inspections, and testing.’ Knut Ording, manager of DNV’s new systems and software reliability unit said, ‘The revision means that yards, owners and suppliers may now more easily determine the scope and efforts related to implementing ISDS.’
