CRIOP

CRIOP is a human factors-based risk analysis developed by SINTEF. A CRIOP analysis is performed to verify and validate whether a control centre can safely and efficiently handle all situations.

CRIOP assesses risks in terms of the consequences of human failure. The method comes from the offshore industry and can be used for virtually all workplaces where complex tasks are carried out in organizations with safety-critical processes.

As a human factors specialist, Intergo performed a CRIOP risk analysis for an offshore crane cabin. This CRIOP analysis was a requirement of the client to the crane manufacturer.

Approach

A CRIOP analysis is performed in sessions with a project team with representatives of all stakeholders and consists of two main components:

  • A review performed with a checklist, based on standards, industry standards and best practices;
  • A scenario-based risk analysis.

As usual for application in the design phase, the CRIOP analysis was carried out for the components:

  • Layout (crane cabin layout),
  • Working Environment (environmental factors for the crane cabin),
  • Control and safety systems, man-machine interfaces (safety and control systems, and crane cabin interaction design).

CRIOP assumes an iterative design process. The CRIOP analysis was applied during the preparatory phase, the preliminary design and the detailed design. This is to ensure proper implementation of the generally qualitatively formulated requirements from the underlying standards and industry standards, including:

  • ISO 11064,
  • NORSOK S-002 and I-002,
  • YA-711 EEMUA.

Results

Implementation of the CRIOP risk analysis resulted in significant improvements in the design of the crane cabin. For example, an improved version of the front and roof window, resulting in a better view for the crane operator. In addition, joint implementation of the CRIOP analysis has brought the various departments and the end user closer together.

At the start of the assignment, the analysis was seen as an obligation imposed by the client. Gradually, more attention was given to each other and people from the different departments and representatives of the end-user were thinking constructively together in terms of solutions. The project has therefore not only resulted in product improvements, but also in team building and support for the design.
