Managing Human Factors (HF) in the design of control centres (CC) has become increasingly important in large-scale petroleum projects, because of the impact it has on safety and efficient operations. Integrated Operations (IO) and the "e-field of the future" introduce new ways of working, allowing for virtual teams but raise new risk management issues. In 2006, 22 persons, representing different sectors and actors in the industry were asked about their experiences with ISO 11064. ISO 11064 is the standard "Ergonomic design of control centres" and provides guidance on how to handle HF during design of CC.

This paper presents the present status; summarizing experiences made when applying ISO 11064 in Norwegian petroleum projects and suggest areas of improvements. The purpose of the study has been to assess and improve the standard's usefulness for the purpose of reducing the risks introduced by bad design, and to create new guidelines where such are found necessary.

Results indicate that ISO 11064 contributes positively to structuring and legitimating the HF work. The interdisciplinary approach has proved to be an effective HF risk management tool. Applying the standard gives safer operations; this will reduce risk and allow for increased operative efficiency. However, the study also indicates possibilities of improvement of ISO 11064 in areas such as scope of the standard, organizational issues, work procedures, competence in design and operations, exception handling in a virtual organization, communication to the engineering team and documentation of design results. Thus, additional guidelines and techniques are necessary when designing and managing HF in modern CC.

Several improvements to ISO 11064 are suggested. In particular, a goal-based approach can ensure the standard's future applicability, while accommodating technological changes. A survey is planned to follow up on the results to elaborate the findings in the study.

1. Introduction

"HF (ergonomics) is the scientific discipline concerned with the understanding of interactions among human and other elements of a system, and the profession that applies theory, principles, data and methods to design in order to optimize human well-being and overall system performance"[1]. The main objective of this exploratory study is to map experiences from applying ISO 11064 to CC design in full scale industrial projects, e.g. construction of new offshore installations (oil platforms, FPSOs) and onshore process installations as well as major CC modifications of the same.
