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 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), Scenario Analysis of key scenarios 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 when the CRIOP® analysis should be performed. This version of CRIOP® was developed in 2003 and 2004, with minor adjustment done in 2008.
