“…The temporality of the work situation is an important factor in understanding the relationship between representations of work and situated practice. In some types of work, such as the work of control room operators described here, the petroleum processing plant operators described by Kongsvik et al (2015) or infrastructure technicians described in Almklov and Antonsen (2014), creatively situating planned activities in a temporally unfolding situation is a core task. In all these settings, the workers deal with unique situational contingencies.…”

“…This is also precisely what enables the continuous improvement of the Safety Management System (SMS), improve situational awareness of operational managers and, consequently, the safety culture related to this singular major accident hazard. These combination leads to improved decisionmaking processes which are, as demonstrated by Kongsvik et al (2015), a central component of the management of safety-critical operations;…”

Accident Precursor Probabilistic Method (APPM) for modeling and assessing risk of offshore drilling blowouts – A theoretical micro-scale application

This paper proposes and explains the application of an accident precursor probabilistic method (APPM) that aims to overcome the usual limitations of existing quantitative risk analyses (QRA), with a focus on offshore drilling blowouts. This limitation is implicit in generic QRAs that do not appropriately reflect the specificities of the rig and its environment, without considering systems arrangements, risk influencing factors (RIF) or current operational conditions. The proposed method is divided into three pillars: (i) a guideline for modeling the blowout probability considering specific conditions or well, rig, safety barriers and risk influencing factors (RIF) objectives; (ii) a proposed axiom combined with a scoring system to quantify the RIF into the QRA; and (iii) a risk based plan framework, to allow risk update and sequential learning during the operational phase. The APPM is based on a Bayesian Network (BN) mathematical framework. It allows the pre-defined axiom to be entered into a conditional probability table (CPT). This approach, combined with the assessment of the company's safety management system, allows the incorporation of RIF into the QRA. The developed APPM is applied to a theoretical micro-scale calculation. The result demonstrates its suitability for addressing common aspects inherent to the blowout phenomenon, including uncertainty, dependability between variables (common cause factors and redundant failures), and dynamism due to planned or unplanned operational changes in systems, drilling parameters and current conditions of RIF. Limitations of the APPM are also identified, and suggestions are made for future work on this topic.

Situated Practice and Safety as Objects of Management

This chapter focuses on the relationship between representations of work (rules, procedures, models, specifications, plans) and work as a situated practice, performed by real people in always unique contexts. Empirically, it is organized around two main examples, the first one being a discussion of the compartmentalization of safety seen in shipping and the railway sector. It shows how safety, as an object of management, has become decoupled from practice, and how current discourses about safety disempower practitioners and subordinate their perspectives to more "theoretical" positions. The second is based on a study of control room operators in a space research operations setting. Here safety in the sense of avoiding harm to people is not the main concern; rather it is the reliability and robustness of an experiment on the International Space Station that is at stake. This example serves as a starting point for discussing how the research and theory on industrial safety should address the different temporalities of different work situations. It also helps to discuss the role of rules and procedures to support safety, reliability and resilience within the field of safety science. Finally, some propositions about the relationship between situated practice and the management of safety are provided: how invisible aspects of situated work might be important for safety yet hard to manage, how procedures and rules might be integrated parts of situated work as much as representations of it and how different temporalities of work situations should be included in the theorizing of safety and resilience.
