Abstract
CRIOP is a methodology used to verify and validate the ability of a control centre to safely and efficiently handle all modes of operations including start up, normal operations, maintenance and revision maintenance, process disturbances, safety critical situations and shut down. The methodology can be applied to central control rooms, emergency control-rooms, drillers' cabins, cranes, ship bridges and other types of cabins, both onshore and offshore. The key elements of CRIOP are checklists covering relevant areas in design of a Control Centre (CC) i.e. “work as imagined”, scenario analysis of key scenarios exploring “work as done” and a learning arena where the workforce with operating experience, designers and management can meet and evaluate the optimal CC. A CRIOP analysis is initiated by a preparation and organisation phase, to identify stakeholders, gather necessary documentation, establish analysis group, and decide timing. This version of CRIOP was developed based on user requirements, experiences of use in actual projects and best practices from 2003, 2004, 2008, 2011, 2024 and 2025.
